Sick Leave 
 
Summary 
Full-time federal civilian employees receive 13 days of sick leave each year, and may carry over 
an unlimited amount of unused sick leave from year to year. At the time of retirement, employees 
in the Civil Service Retirement System (CSRS) (those hired before 1984) receive credit in the 
computation of their civil service retirement annuities for any unused sick leave they have at the 
time of retirement. Until October 2009, employees in the Federal Employees Retirement System 
(FERS) (those hired after 1983 and others who transferred to FERS) generally received no credit 
for unused sick leave at the time of retirement. As a result, some believed that FERS employees 
would use more of their sick leave as they approach retirement (resulting in productivity losses) 
than their CSRS counterparts. The conference report for the legislation creating FERS in 1986 
urged the Office of Personnel Management (OPM) to examine this issue. FERS employees 
comprise an increasing percentage of the federal workforce, and by 2014 virtually all federal 
employees are expected to be in FERS. 
In 2004, CRS obtained data indicating that FERS retirees and FERS employees in that group who 
were eligible to retire or approaching eligibility used substantially more sick leave and had much 
lower sick leave balances than comparable CSRS retirees and employees. In 2006, OPM similarly 
concluded that FERS employees who were eligible to retire or were nearing eligibility used more 
sick leave than their CSRS counterparts, but concluded that to make sick leave creditable under 
FERS would cost several times more than the potential productivity savings. In April 2008, the 
Treasury Inspector General for Tax Administration concluded that the lack of compensation for 
unused sick leave was causing FERS employees in the Internal Revenue Service to use more sick 
leave than their CSRS counterparts. 
In the 111th Congress, Representative Jim Moran introduced H.R. 958, which would permit 
retiring FERS employees to receive service credit for unused sick leave. Similar provisions were 
added to legislation providing the Food and Drug Administration with certain authority to 
regulate tobacco (H.R. 1256), but those provisions were not included in the final legislation (P.L. 
111-31). The House-passed version of the 2010 Department of Defense authorization legislation 
(H.R. 2647) contained the FERS sick leave provisions, but the Senate-passed version (S. 1390) 
did not. Conferees agreed to include the sick leave provisions in the final legislation, but to phase 
in the service credit over four years (with 50% credit for unused sick leave until the end of 2013, 
and 100% credit starting in 2014). The House agreed to the conference report (H.Rept. 111-288) 
on October 8, 2009, and the Senate agreed on October 22, 2009. The President signed the 
legislation on October 28, 2009 (P.L. 111-84). The amount of increase in an employee’s annuity 
varies substantially based on the employee’s high-three average salary and sick leave balance at 
the time of retirement, and whether they retire before or after January 1, 2014. 
According to a 2004 study, all but a few state governments provided some type of compensation 
to employees for unused sick leave at retirement, usually either as cash payments, service credit 
in the computation of annuities, or payment of health or life insurance premiums. The states 
generally limited these payments in some way (e.g., capping the number of hours of sick leave 
payable). 
This report will not be updated.

Sick Leave 
 
Introduction 
Pensions for nearly all federal civilian employees are provided through one of two retirement 
programs—the Civil Service Retirement System (CSRS) or the Federal Employees Retirement 
System (FERS).1 Most federal civilian workers hired before January 1, 1984, are covered by 
CSRS, whereas those hired after that date are covered by FERS (as are employees who 
voluntarily switched from CSRS to FERS during “open seasons” held in 1987 and 1998). 
CSRS and FERS are similar in several respects. In both retirement systems, employees’ annuities 
are a function of age, length of federal service, and final average pay.2 The normal retirement age 
(without reduction of annuity) under both CSRS and FERS is 55 for employees born before 1948 
who have at least 30 years of service.3 Both retirement systems also allow normal retirement at 
age 60 for employees with 20 or more years of service, and 62 for employees with at least five 
years of service. Also, employees in both systems receive 13 days (104 hours) of sick leave each 
year, and may carry over an unlimited amount of unused sick leave from year to year. Therefore, 
an employee who carries over an average of nine days (72 hours) of sick leave each year during a 
30-year career would accumulate 2,160 hours of unused sick leave by the time he or she is 
eligible to retire. 
Until October 2009, one of the many ways in which CSRS and FERS differed was in how 
accumulated sick leave was accounted for at the time of retirement. 4 In the CSRS system, retiring 
employees receive service credit in the computation of their annuities for any unused sick leave 
they had at the time of retirement. For example, a retiring CSRS employee with 30 years of 
service and one year (2,087 hours) of accumulated sick leave would be considered to have 31 
years of service for purposes of annuity computation.5 In sharp contrast, FERS retirees generally 
received no service credit or other type of compensation for their accumulated sick leave.6 As a 
result, some observers suggested that FERS employees would be on sick leave more frequently 
than CSRS employees, particularly as they approach retirement age, thereby resulting in reduced 
productivity, increased personnel costs, or both. Reports of FERS employees actually carrying out 
this “use it or lose it” behavior periodically appeared in press articles.7 
                                                             
1 Although the federal government has many different retirement plans, CSRS and FERS are by far the largest. In this 
report, “federal civilian employees” refers to those in the CSRS or FERS plans. For a more thorough discussion of 
these two plans, see CRS Report 98-810, 
Federal Employees’ Retirement System: Benefits and Financing, by Patrick 
Purcell. 
2 FERS annuities are generally smaller than in CSRS because they are only one component of the system. A more 
detailed description of the two systems is provided later in this report. 
3 The FERS normal retirement age increases for employees born in 1948 or later, and eventually reaches age 57 for 
employees born in 1970 or later. 
4 As discussed later in this report, a provision in the Department of Defense Authorization Act for 2010 (P.L. 111-84, 
October 28, 2009) changed this element of FERS.  
5 The congressionally mandated number of hours in a work year is 2,087. Only full years and months are counted in the 
annuity computation. For example, if a full-time employee worked 30 years and had 835 hours (four months and 24 
days) of accumulated sick leave at the time of retirement, the employee would be credited with 30 years and four 
months of service; the 24 additional days would be dropped. 
6 FERS employees who transferred from CSRS receive credit for sick leave balances at the time of the transfer or at the 
time of retirement, whichever is smaller.

leave,”

Sick Leave 
 
To discourage this phenomenon from occurring, some observers advocated changing FERS to 
provide some kind of value for unused sick leave (e.g., allowing full or partial service credit to be 
used in annuity calculations, or providing full or partial lump-sum cash payments for such 
leave).8 For example, in April 2006, a coalition of federal management groups (the Federal 
Managers Association, the Senior Executives Association, the Federal Aviation Administration 
Managers Association, the National Council of Social Security Management Associations, and 
the Professional Managers Association) called for a change in federal sick leave policy (e.g., 
allowing FERS employees to apply a portion of their unused leave toward post-retirement health 
care policies).9 Others, however, believed that the CSRS sick leave benefit is excessively 
generous, and that FERS should not replicate that generosity. Opponents of a policy change (and 
even some proponents) also pointed out that use of sick leave for unauthorized reasons is 
inappropriate, and that FERS employees knew (or should have known) about this policy when 
they agreed to the terms of employment.10 
This report provides data that CRS obtained on sick leave usage rates by many employees and 
recent retirees in the CSRS and FERS retirement systems in 2003 and 2004. It also discusses a 
study of federal sick leave use in 2005 and 2006 by the Office of Personnel Management (OPM), 
and provides information on unused sick leave policies in private sector and other public sector 
organizations (e.g., state governments). Finally, it discusses the enactment of changes to the 
FERS sick leave policy. First, though, the report provides some background information on CSRS 
and FERS trends and federal sick leave policies in general. 
Background 
As 
Figure 1 below shows, because all new federal employees for more than 20 years have been 
put in FERS, the number of FERS employees in the federal workforce has increased substantially, 
whereas the number of CSRS employees has declined. By September 1996, more federal 
employees were in FERS (818,650) than in CSRS (809,098). As of September 2007, nearly 1.3 
million federal employees were in FERS, compared with about 335,000 in CSRS. At the rate of 
decline in the CSRS population since 1990, by about 2014 virtually all federal employees are 
expected to be in FERS. 
                                                             
8 For example, in testimony before the Senate Committee on Governmental Affairs on February 4, 2004, the President 
of the National League of Postmasters said, “We also need to address the issue of sick leave for FERS employees. 
Currently, they get no credit for unused sick leave at retirement. We need to change this rule so they could sell back 
sick leave or get credit at retirement.” 
9 Deborah Funk and Stephen Losey, “Sick Leave abuse: Managers prescribe cure for use-or-lose rules,” 
Federal Times, 
April 17, 2006, p. 1. 
10 For example, in the “Sick Leave and FERS” article mentioned above, 56% of the respondents to an unscientific 
survey said it was not ethical for a federal employee to use sick leave without having an authorized medical reason for 
using the leave. One respondent said “If you were hired under FERS, then you should go by the rules, and the CSRS 
rules are not your concern.”

Figure 2 shows the number of employees who were eligible to retire (“retirement eligibles”) in 
both the CSRS and FERS retirement systems from September 2000 until September 2007. 
Although the number of CSRS retirement eligibles at the end of this period still exceeded the 
number of FERS eligibles, the difference between the two retirement systems has been steadily 
narrowing in recent years.

Sick Leave 
 
Federal Sick Leave 
Sick leave benefits provide paid time off while an employee temporarily cannot work due to a 
non-work-related illness or injury. As noted previously, all federal civilian employees receive four 
hours of sick leave each biweekly pay period, for a total of 104 hours (13 days) each year. 
Employees must request sick leave within such time limits as their agencies may require, and 
agencies may grant sick leave only when supported by evidence they consider administratively 
acceptable. For absences in excess of three days, or for a lesser period when determined 
necessary by the agency, an agency may require a medical certificate or other administratively 
acceptable evidence before approving sick leave requests. 
The federal sick leave program has been expanded several times, allowing the benefit to be used 
for purposes other than personal medical attention. For example: 
•  the Federal Employees Family Friendly Leave Act of 1994 (P.L. 103-388) 
permitted employees to use up to 13 days of sick leave each year to provide 
medical or personal care to a family member, or to make arrangements for or to 
attend the funeral of a family member.11 
•  the Treasury-Postal Service Appropriations Act for FY1995 (P.L. 103-329) 
permitted the use of sick leave to pursue activities related to the adoption of a 
child. 
•  in 2000, the federal sick leave program was again expanded, allowing employees 
to use up to 12 weeks of sick leave per year to care for family members with a 
serious health condition.12 
According to OPM, federal sick-leave usage rates increased during this period—from an average 
of 8.59 days of sick leave used per year in 1994 to 9.52 days in 2001. One possible explanation 
for this overall increase in sick leave use could be the changes in policy that allowed additional 
uses for sick leave. As explained more fully later in this report, though, another possible 
explanation could be the increasing number of FERS employees who were approaching 
retirement eligibility. 
From time to time, Congress attempts to broaden or otherwise change federal sick leave policy 
even further. For example, in the 110th Congress, one of the provisions in H.R. 2200 proposed 
exempting federal employees who are undergoing medical treatment for a combat-related 
disability sustained while a member of the armed forces from the requirement in the federal leave 
sharing program that they exhaust their annual and sick leave before using any transferred leave. 
A provision in S. 1649 in the 110th Congress would have required OPM to establish a program to 
allow federal employees serving as caregivers to dependents of members of the armed forces 
deployed overseas to use their sick leave in the same manner as annual leave is used. (Note: A 
                                                             
11 The act guaranteed full-time employees the use of five days (40 hours) of sick leave each year to care for family 
members or for bereavement purposes. Employees wanting to use more than five days had been required to maintain a 
sick leave balance of at least 80 hours. However, in 2006, OPM issued final regulations that removed this requirement.

balance of at least 80 hours. However, in 2006, OPM issued final regulations that removed this requirement. See U.S.

Sick Leave 
 
subsequent “Legislative Developments” section of this report discusses a broader proposed 
change in federal sick leave policy.) 
CSRS and Sick Leave 
The Civil Service Retirement Act of 1920 (P.L. 66-215) created CSRS to provide pension benefits 
to federal employees. CSRS is a “defined benefit” retirement plan in that the benefit is paid as a 
lifelong annuity based on years of service and average salary in the last few years of employment. 
CSRS employees accrue benefits equal to 1.5% of their highest three consecutive years of base 
pay (often called the employee’s “high-three” pay) for their first five years of service, 1.75% of 
their “high-three” pay for each year in years 6 through 10, and 2% of their “high-three” pay for 
each subsequent year. Therefore, a CSRS employee who retires with 30 years of service would 
receive an annuity equal to 56.25% of the employee’s “high-three” pay. CSRS annuities are 
adjusted annually for inflation and are financed by contributions from both employees and the 
government (although the CSRS system is currently not fully funded).13 
Until 1969, CSRS employees forfeited any unused sick leave at the time of their retirement. At 
that time, the Civil Service Commission (now OPM) estimated that about half of all retiring 
federal employees had zero sick leave balances, and the other half had an average of about 44 
days (352 hours) of sick leave that were forfeited at retirement. Also, a House Post Office and 
Civil Service Committee report noted that retiring employees used an average of 40 days (320 
hours) of sick leave during their last year of employment.14 
In 1969, Congress enacted legislation (P.L. 91-93) to permit CSRS employees to receive service 
credit for unused sick leave in the computation of their retirement annuities. This change in policy 
made unused sick leave highly valuable. For example, as noted previously, an employee retiring 
with 30 years of service and a year of unused sick leave would get credit for 31 years of service 
for purposes of annuity computation. If this employee’s “high-three” salary was $50,000, the 
additional year of service would increase his or her pre-tax retirement annuity by 2%, or $1,000 
per year. Therefore, even before indexing for inflation, if the employee received the annuity for 
20 years, the unused sick leave would be worth about $20,000. To pay for this and other changes 
in the retirement system, the law increased employee and agency contributions to the civil service 
retirement fund from 6.5% to 7.0% of pay. 
This change in policy was expected to reduce federal employees’ use of sick leave and to grant 
limited recognition to those who prudently utilized their sick leave. In 1986, the General 
Accounting Office (GAO, now the Government Accountability Office) examined the 
implementation of this change in policy, and reported that employees who retired in 1984 and 
1985 had significantly higher sick leave balances than employees who retired in 1968, before the 
law was changed.15 Specifically, the average sick leave balances for employees who retired in 
1984 and 1985 were 38% and 46% higher, respectively, than the estimated average balance of

Federal Workforce: Retirement Credit Has Contributed to Reduced Sick 
Leave Usage, GAO/GGD-86-77BR, June 1986. 
15 GAO/GGD-86-77BR. Specifically, GAO reported that retirees in 1968 had an average of 642 hours of unused sick 
leave. Retirees in 1984 averaged 884 hours and retirees in 1985 averaged 940 hours—about 38% and 46% higher, 
respectively, than the average retirees’ leave balance in 1968.

1968 retirees. GAO concluded that the changes made in 1969 had “contributed to reducing the 
overall usage of sick leave and increasing the unused sick leave balances of retiring federal 
employees.” 
FERS and Sick Leave 
The Federal Employees’ Retirement System Act of 1986 (P.L. 99-335) created FERS with three 
basic elements—(1) Social Security, (2) a FERS basic annuity, and (3) a thrift savings plan (TSP). 
•  The Social Security component is based on wages earned while a federal 
employee. Employees may begin receiving reduced Social Security benefits at 
age 62, but may receive a portion of that amount in the form of a FERS 
supplement as early as age 55. 
•  The FERS basic annuity is a defined benefit plan in which employees retiring 
below age 62 accrue benefits at the rate of 1% of their “high-three” average pay 
per year of service. Therefore, a FERS employee retiring at age 58 with 30 years 
of service will accrue a pension benefit equal to 30% of his or her “high-three” 
average pay.16 Like CSRS, FERS annuities are funded by contributions from 
employees and the government, but (unlike CSRS) FERS benefits must be pre-
funded according to their full actuarial costs. FERS annuitants over age 62 
receive annual cost-of-living adjustments, but those adjustments may be less than 
the amount of inflation.17 
•  The TSP is patterned after the “401(k)” savings plans available in the private 
sector, and encourages employees to save for retirement by making contributions 
“pre-tax” and by making interest earned on these contributions non-taxable until 
they are withdrawn. The government contributes 1% of pay for all FERS 
participants, and provides whole or partial matches for up to 5% of pay 
contributed by FERS employees. The maximum annual employee contribution is 
$16,500.18 
In contrast to the approach taken with regard to CSRS employees in 1969, Congress did not 
authorize FERS employees to receive service credit for unused sick leave (except for leave 
carried into the system by employees who transferred to FERS from CSRS).19 The legislative 
history for the 1986 act creating FERS does not explain why Congress took this approach. 
However, in the conference report for the act, the conferees noted that FERS employees’ unused 
sick leave generally could not be used in the computation of their annuities, and urged OPM to 
examine sick leave usage by FERS employees. The conferees went on to say that they were 
“concerned that without an incentive to save sick leave, the use of sick leave may substantially 
                                                             
16 FERS employees who have at least 20 years of service and who work until at least age 62 earn 1.1% for each year of 
service. Therefore, an employee who retires at age 62 with 30 years of service will accrue a pension benefit equal to 
33% of his or her “high-three” average pay. 
17 For example, if the amount of inflation is more than 3%, the annuitant would receive an adjustment equal to the 
amount of inflation minus 1 percentage point. 
18 Employees age 50 and older can also make catch-up contributions of up to $5,500 per year. CSRS employees can 
contribute to the TSP, but they receive no government matching contribution. 
19 Retiring employees who transferred to FERS receive service credit for the amount of unused sick leave they had at 
the time of transfer or the time of retirement, whichever is less.

increase.”20 OPM did not conduct this study until 2006, and the study is described and analyzed 
later in this report. OPM representatives told CRS that their office had not conducted the study 
previously because the agency’s Central Personnel Data File does not contain data that would 
allow comparison of sick leave usage rates or sick leave balances by employees in different 
retirement plans.21 
Indications of Greater Sick Leave Use by FERS Employees 
There have been indications for some time that FERS employees may be using sick leave more 
often than their CSRS counterparts, particularly as they approach retirement. As noted previously, 
average sick-leave usage rates for all federal employees increased by more than 10% from 1994 
to 2001 (rising from 8.59 days per year in 1994 to 9.52 days per year in 2001). One possible 
explanation for this increase is the additional uses for sick leave that were allowed during that 
period (e.g., to care for sick family members or to adopt a child). However, another explanation 
could be the increasing numbers of FERS employees in the federal workforce and the fact that 
they received no benefit for accrued sick leave at retirement. The percentage of full-time, 
permanent federal civilian employees in FERS increased from about 46% in 1994 to about 62% 
in 2001.22 
Also, a May 2004 survey suggested that FERS employees were more likely to use sick leave as 
they approach retirement than their CSRS counterparts. FPMI Solutions, Inc., a human resources 
services, staffing, and training company primarily for federal agencies, conducted an unscientific 
online poll of its subscribers (current and retired federal employees) regarding sick leave usage. 
Of the more than 2,300 participants in the poll, 51% said they were under CSRS and 49% said 
they were under FERS. Although both groups of participants said they were strongly in favor of 
sick leave conservation, the groups diverged regarding sick leave use in the last year before 
retirement. Whereas nearly 85% of CSRS employees and retirees said they would or did conserve 
as much sick leave as possible, more than 75% of FERS employees and retirees said they planned 
to use as much sick leave as possible during their last year before retirement. One respondent said 
that there was “a huge incentive for CSRS and offset employees to conserve sick leave and a very 
large disincentive for FERS employees to do the same.”23 Another respondent said that this 
incentive structure caused “a lot of productivity to go down the drain.” However, other 
respondents said that, this incentive structure notwithstanding, the use of sick leave when not sick 
was morally “the wrong thing to do.” 
A more scientific study of sick leave use within the Bureau of Prisons from 1994 through 2003 
indicated that FERS employees in the agency were, in fact, using more sick leave than those in 
CSRS, even when controlling other possible factors (e.g., race, gender, education, age, and sick

22 These percentages include employees in federal retirement systems other than FERS or CSRS (e.g., employees in the 
foreign service retirement system). 
23 CSRS “offset” retirement generally applies to employees who had a break in service that exceeded one year and 
ended after 1983, and had five years of creditable civilian service on January 1, 1987. When these employees become 
eligible for Social Security benefits, their annuities will be offset by the value of the Social Security Benefit earned 
during CSRS offset service.

leave balances of employees).24 The authors concluded that the study’s findings “strongly suggest 
that the apparent difference between the incentive systems in the CSRS and FERS systems 
regarding the use of sick leave is translated into actual differences in behaviors of CSRS and 
FERS employees.”25 
FERS Employees Use More Sick Leave Than Their 
CSRS Counterparts 
Although OPM’s Central Personnel Data File does not contain data on sick leave usage rates by 
employees in different retirement systems, those data are available from each federal agency or, 
more centrally, through organizations that administer payroll functions for multiple federal 
agencies. For example, the Defense Finance and Accounting Service (DFAS) administers payroll 
functions for nearly 700,000 civilian employees in the Department of Defense and the Executive 
Office of the President. 
In 2004, CRS requested data from DFAS on sick leave usage rates and sick leave balances for 
employees and retirees in the agencies they service. We focused on full-time, permanent 
employees in General Schedule (GS) and Wage Grade (WG) (or equivalent) pay systems, which 
included more than 500,000 employees in CSRS and FERS—about one-third of the full-time 
permanent workforce outside of the Postal Service, intelligence agencies, and law enforcement.26 
Our data request was essentially in two parts. First, for employees who did not retire during the 
one-year period from June 1, 2003, through May 29, 2004, we requested the average number of 
sick leave days used during that period and average sick leave balances as of the end of that 
period for the following categories: 
•  employees in CSRS and (separately) employees in FERS who were “eligible to 
retire” without penalty as of June 1, 2003 (i.e., at least 55 years of age and with at 
least 30 years of service, or at least 60 years of age and 20 years of service, or 62 
years of age and 10 years of service).27 
•  employees in CSRS and (separately) employees in FERS who were eligible to 
retire and “almost eligible to retire” (defined as being within two years of 
retirement eligibility in terms of any combination of age or service—e.g., an 
employee who is 53 with 30 years of service or 55 with 28 years of service, or an 
employee who is 58 with 20 years of service or 60 with 18 years of service). 
•  employees in CSRS and (separately) employees in FERS who were eligible to 
retire and “nearing eligibility to retire” (defined as being within five years of 
retirement eligibility in terms of any combination of age or service—e.g., an

employee who is 55 with 20 years of service or 60 with 15 years of service). 
Second, for employees who retired during the June 1, 2003, through May 29, 2004, period, we 
asked for the average number of sick leave days used per pay period when they were working and 
their average sick leave balance as of their date of retirement. 
Differences in Sick Leave Usage and Balances 
The Defense Manpower Data Center acted as DFAS’s agent to generate the sick leave 
information that we requested.28 As 
Table 1 shows, the data indicated that FERS employees in the 
agencies that DFAS supports who were eligible to retire or approaching eligibility generally used 
more sick leave than their CSRS counterparts during the one-year period ending May 29, 2004. 
The differences between the two groups were greatest for GS employees as they approached or 
achieved retirement eligibility. For example, whereas FERS employees in the GS pay system who 
were either eligible to retire or were within five years of retirement eligibility used only slightly 
more sick leave during the year than comparable CSRS employees (89 hours versus 85 hours, 
respectively), FERS employees who were eligible to retire or within two years of eligibility used 
25% more sick leave than their CSRS counterparts (105 hours versus 84 hours, respectively). 
FERS employees who were eligible to retire used nearly 35% more sick leave than comparable 
CSRS employees (119 hours versus 89 hours, respectively). FERS employees in the WG pay 
system who were eligible to retire or were within two years of eligibility also used somewhat 
more sick leave than their CSRS counterparts (e.g., 139 hours versus 127 hours in the “eligible to 
retire” category), but the differences between FERS and CSRS employees were not as significant 
as in the GS pay system.29

information requirements of the Office of the Under Secretary of Defense for Personnel & Readiness and other 
members of the Department’s manpower, personnel, and training communities. 
29 The number of WG employees in each of these categories was also significantly smaller than the number of GS 
employees. For example, there were more than 33,000 CSRS employees in the GS system who were eligible to retire, 
compared to about 5,500 WG employees in that category.

Differences between CSRS and FERS employees were even more pronounced when considering 
their average sick leave balances as of May 2004. As 
Table 2 shows, FERS employees’ sick leave 
balances in all three retirement eligibility categories were only about half as large as their CSRS 
counterparts (and in some cases were less than half as large). The differences between FERS and 
CSRS employees were about the same in both the GS and WG pay systems.

As 
Table 3 shows, for employees who retired from June 2003 through May 2004, FERS retirees’ 
sick leave balances at the time of retirement were significantly smaller than the sick leave 
balances of CSRS retirees. CSRS retirees (particularly within the GS pay system) also had lower 
average days of sick leave used per pay period prior to their retirement than their FERS 
counterparts.

Some (and perhaps most) of the differences in leave balances between employees in CSRS and 
FERS may be due to differences in length of service rather than their retirement systems. For 
example, the DFAS data indicated that CSRS employees who were eligible to retire had an 
average of nearly 34 years of service, compared with nearly 24 years of service for FERS 
employees. Similarly, CSRS employees who retired averaged nearly 32 years of service, 
compared with nearly 24 years of service for employees in FERS. However, differences in 
longevity between these groups do not explain why FERS employees’ use of sick leave and FERS 
retirees’ use of sick leave just before retirement was greater than their CSRS counterparts.

OPM’s 2006 Study of Sick Leave Usage 
In May 2006, CRS contacted DFAS in an attempt to obtain more recent data on federal 
employees’ sick leave usage rates. OPM responded to CRS, indicating that it was conducting its 
own study in response to a request from a Member of Congress (who had reminded OPM that 
Congress had urged the agency to conduct such a study in 1986). In October 2006, OPM reported 
to the Member of Congress on the results of the study, and the Member’s office shared those 
results with CRS. The overall design of the study was similar to the design that CRS used in its 
2004 study, but the data covered more employees. Specifically, OPM obtained sick leave use data 
on full-time permanent, non-Postal Service employees from the four major federal payroll 
providers: DFAS (the organization providing data to CRS in 2004), the Department of the 
Interior’s National Business Center, the Department of Agriculture’s National Finance Center, and 
the General Services Administration’s National Payroll System. The study focused on the amount 
of sick leave used by three groups of FERS and CSRS employees between April 2005 and March 
2006: (1) those already eligible to retire without penalty; (2) those “nearly eligible” to retire (i.e., 
within two years of being eligible); and (3) all other employees. OPM also examined sick leave 
use by FERS and CSRS employees who had retired during this period. 
Some of the OPM study’s results appear similar to the results of the earlier CRS study. As 
Table 4 below shows, the OPM study indicated that FERS employees who were eligible to retire used an 
average of 20.2 more hours of sick leave per year from April 2005 through March 2006 than their 
CSRS counterparts. (As described in 
Table 1 above, the CRS study indicated that white-collar 
FERS employees who were eligible to retire used 30 hours more sick leave per year in 2003 and 
2004 than their CSRS counterparts; blue-collar FERS employees who were retirement eligible 
used about 12 hours more sick leave per year than similar blue-collar CSRS employees.) Among 
employees who were within two years of retirement eligibility, OPM reported that FERS 
employees used an average of 13.5 more hours of sick leave per year than CSRS employees. (In 
the CRS study, the FERS-CSRS difference for employees eligible and nearly eligible to retire was 
21 hours for white-collar employees, and five hours for blue-collar employees.) OPM reported 
that there were only minor differences in leave usage rates between other FERS and CSRS 
employees.

However, in one area the results of the OPM study differed substantially from the CRS study. 
Among employees who had retired between April 2005 and March 2006, the OPM study 
indicated that FERS employees used an average of 3.3 hours 
less sick leave per year than 
employees who were in CSRS (22.8 hours per pay period for FERS compared with 26.1 hours per

pay period for CSRS).30 (In contrast, the CRS study indicated that white-collar employees in 
FERS who retired in 2003 and 2004 used 2.5 
more hours of sick leave per pay period than their 
CSRS counterparts. For blue-collar workers the FERS-CSRS difference was 0.2 hours more per 
pay period.) 
OPM said it did not believe that the higher rate of sick leave use by FERS employees who were 
eligible and nearly eligible to retire was solely attributable to the fact that they do not receive 
retirement credit for unused sick leave. The agency said other possible explanations included 
demographic differences between employees in the two retirement systems and the increased 
number of ways that sick leave can be used. Nevertheless, using what it characterized as “the 
unproven assumption that the entire difference in sick leave usage ... is solely attributable to the 
fact that FERS employees do not receive retirement credit for unused sick leave,” OPM estimated 
that the lost productivity caused by increased use of sick leave by FERS employees who were 
eligible or nearly eligible to retire cost the federal government $68 million during the April 2005 
through March 2006 period. OPM estimated that providing FERS employees with service credit 
for unused sick leave would increase costs to the retirement fund by about $180 million annually, 
and would increase the retirement fund liability by about $2 billion, amortization of which would 
require annual payments of about $137 million over 40 years. In total, OPM said “to pay for 
future costs and to amortize the cost of benefits based upon past service would have an annual 
cost of about $317 million.” Therefore, OPM concluded that “to make sick leave creditable under 
FERS would cost several times more than the potential savings.” 
Analysis of the OPM Study 
Several elements of the OPM study could have affected OPM’s conclusions.31 First, the reasons 
that OPM suggested as alternative explanations to why FERS employees are using more sick 
leave than CSRS employees can be questioned. OPM said one such reason could be the 
differences in the demographic characteristics of employees in the two retirement systems (e.g., 
age differences between FERS and CSRS employees). However, these hypothesized effects can 
be tested statistically, and the results of such tests in one federal organization do not appear to 
support OPM’s conclusions. As noted earlier in this report, a 2005 study of employees at the 
Federal Bureau of Prisons concluded that demographic differences between FERS and CSRS 
employees could not explain differences in sick leave use rates between employees in the two 
retirement systems.32 Instead, the authors concluded that differences in sick leave use were 
directly attributable to differences in how unused sick leave is treated in the two retirement 
systems. Another reason that OPM said could cause the FERS-CSRS difference in sick leave use 
was the increased number of ways that sick leave can be used (e.g., for adoption of a child or to 
care for a sick family member, up to specified limits). However, this seems an unlikely 
explanation for FERS-CSRS differences in leave usage within the same time period, particularly 
since both FERS and CSRS employees could use their sick leave for all of these purposes. 
                                                             
30 It is not clear how OPM determined an annual rate of sick leave usage for employees who retired in the first few 
months of this one-year period. 
31 CRS raised these and other issues with officials in both the OPM pay group that did the study and OPM’s office of 
congressional relations in October 2006. CRS also requested the leave usage data that OPM used in its study to verify 
the results of the study. Despite this and several other subsequent inquiries, as of March 2008, CRS has not received a 
response from OPM.

Among Correctional Workers.”

Sick Leave 
 
Second, at least some of the data that OPM used in the study appear to be of questionable validity. 
For example, OPM said that CSRS employees who had retired between April 2005 and March 
2006 used 26.1 hours of sick leave per pay period, while FERS employees who retired during this 
period used 22.8 hours per pay period. Because each federal pay period is 80 hours, OPM’s data 
suggest that CSRS retirees were on sick leave nearly one-third of the time that they worked 
during their last year of service, and FERS retirees were on sick leave nearly as much. While 
these levels of sick leave use are possible, the levels seem unusually high (i.e., nearly 600 to 700 
hours per year on an annual basis), and are about three times higher than the DFAS data that were 
provided to CRS just two years earlier. Also, the OPM data indicated that CSRS employees (who 
receive significant value for their unused sick leave) used more sick leave per pay period than 
FERS employees (who receive nothing for unused sick leave)—again, counter to what the DFAS 
data indicated in the CRS study, and counter to what one would expect given the current incentive 
structure. 
Also, OPM did not explain in any detail how it arrived at its estimates of the cost of lost 
productivity, or its estimate of the cost of providing FERS employees with service credit for their 
unused sick leave balances. For the lost productivity estimate, OPM said that it was a function of 
the number of FERS employees eligible or nearly eligible to retire times the employees’ average 
salary times the difference in the number of hours of sick leave used. OPM identified the number 
of employees in each retirement system who were eligible or nearly eligible to retire, as well as 
the average differences in sick leave use for each group, but did not indicate what value(s) it used 
for the average salary of these employees. Based on its $68 million productivity cost estimate and 
knowing the other variables, though, it appears OPM assumed an average salary of nearly $54 per 
hour, or about $112,000 per year. However, OPM data on the federal workforce as a whole in 
March 2006 indicate that the average salary for full-time, permanent employees was less than 
$66,000 per year (or less than $32 per hour). For such employees who were ages 50 to 54 with 25 
to 29 years of service (i.e., those close to retirement eligibility), the average salary was less than 
$77,000 per year (or less than $37 per hour). Therefore, assuming all other factors in the equation 
stayed the same (number of FERS employees eligible and nearly eligible to retire, and leave 
usage patterns for employees in those groups), OPM’s estimate of the annual cost of lost 
productivity for these FERS employees may be accurate. 
Finally, and most notably, the only policy option that OPM appears to have considered in its study 
was to give FERS employees full service credit for unused sick leave—an option that was 
characterized by one retirement expert as the “most obvious—and most expensive” option.33 
However, as the discussion of non-federal sick leave policies earlier in this report makes clear, a 
number of other, less expensive policy options are potentially available to encourage FERS 
employees to save their sick leave, including partial service credit, lump sum payments for a 
portion of unused sick leave (based on either the cash value of the sick leave or the value of the 
service credit), or applying all or a portion of the value of an employee’s sick leave balance to the 
cost of the employee’s retirement health care premium. Had OPM considered these other options, 
its conclusions regarding the economic feasibility of providing value for unused sick leave may 
have been different. Different approaches and formulas might be tested with focus groups of 
federal employees to determine which method yields the greatest incentive at the least cost to the 
government.

Sick Leave 
 
On the other hand, and as suggested earlier, a completely different way to reduce sick leave use 
by FERS (and CSRS) employees is to impose more stringent management policies and controls 
on the use of sick leave. Or, perhaps some combination of “carrot” and “stick” approaches could 
be tried. The first step, though, may be to have OPM or some other entity conduct a 
comprehensive, transparent, and methodologically defensible study of federal sick leave usage 
trends, with defensible estimates of the costs associated with various policy options that Congress 
could consider. 
Treasury Inspector General Report 
On April 24, 2008, the Treasury Inspector General for Tax Administration (TIGTA) issued a 
report concluding that Internal Revenue Service (IRS) employees in FERS were more likely to 
use sick leave than CSRS employees, especially as they approached retirement.34 TIGTA said it 
believed that “the lack of compensation for unused sick leave at retirement has contributed to the 
higher amount of sick leave used by FERS employees,” and recommended that the IRS Chief 
Human Capital Officer ensure that all IRS managers receive training on leave policies to increase 
awareness of sick leave abuse and improve sick leave administration. The Chief Human Capital 
Officer agreed with the findings, but questioned how training would resolve the issue of increased 
sick leave use by FERS employees. Overall, TIGTA reported that 97,000 IRS employees took 
more than 15 million hours of sick leave in 2005 and 2006, costing IRS $450 million in salary 
plus lost productivity. 
Sick Leave Policies in Other Organizations 
According to the Bureau of Labor Statistics (BLS), 57% of workers in private industry received 
paid sick leave in March 2007.35 That figure rose to 68% for full-time workers, and to 80% for 
employees in management, professional, and related occupations. On the other hand, only 39% of 
employees in service occupations had access to paid sick leave in 2007, and only 23% of part-
time workers. Large employers were more likely to offer sick leave; 67% of employers with at 
least 100 workers offered the benefit, compared with 48% of employers with fewer than 100 
workers. Other studies have indicated that the absence of sick leave can have a wide range of 
negative effects on family members and coworkers.36 
Other BLS data indicated that 53% of full-time employees with paid sick leave in medium and 
large private establishments in 1997 were allowed to carry over unused sick leave from year to 
year.37 Seventeen percent were allowed to obtain cash in exchange for unused sick days at the end

of the year. Where a cash-in provision was provided, roughly half (9%) also had a provision in 
their plan allowing leave to be carried over from year to year. For 36% of employees, neither 
carrying over nor cashing in of unused sick leave was allowed; any leave not used in the year it 
was earned was forfeited. 
BLS data indicate that all (100%) full-time employees in state and local government were 
provided sick leave in 1998.38 These employees generally received a fixed number of days per 
year, most commonly between 10 days and 15 days. State and local employees with sick leave 
were much more likely than their private sector counterparts to be able to carry over unused sick 
leave from year to year (94% versus 53% in medium and large private sector establishments), 
with about 12% of state and local employees able to both carry over sick leave and receive cash 
payments (compared to 9% in medium-to-large private sector firms). Only 3% of state and local 
employees forfeited any unused sick leave at the end of the leave year (compared to 36% in the 
private sector). 
Unused Sick Leave 
The BLS data did not include specific information on how unused sick leave was treated at 
retirement in either the public or private sectors. However, some surveys of public sector 
organizations’ personnel policies did contain that information. For example, according to a 2002 
survey of 428 agency members of the International Personnel Management Association, 58% of 
the agencies cashed out sick leave at retirement, 45% offered cash for unused sick leave, 11% 
converted sick leave to vacation time, 9% converted sick leave to insurance at retirement, and 3% 
converted sick leave to disability insurance.39 In some cases, though, the agencies limited the 
amount of sick leave that employees could carry over from year to year or limited the amount 
payable at retirement.40 
Federal regulations sometimes provide compensation for unused sick leave at retirement for non-
federal employees. For example, employees in federal Fishery Management Councils may 
accumulate unused sick leave without limit (with Council approval), and “distributions of 
accumulated funds for unused sick leave may be made to employees upon his or her retirement, 
or to his or her estate upon his or her death, as established by the Council.”41 Police officers, 
firefighters, and teachers in the District of Columbia who retire on an immediate annuity receive 
service credit for unused sick leave.42

Sick Leave 
 
Sick Leave Policies in State Governments 
In one of the most comprehensive assessments of employee benefits in state governments, 
Workplace Economics, Inc., reported that as of January 1, 2004, most states provided their 
employees with a fixed number of sick days per year (most commonly between 12 and 15 days), 
but in several states the amount of sick leave accrual was tied to years of service, date of hire, or 
both. For example, in Hawaii, state employees hired before July 2, 2001, accrue 21 days of sick 
leave per year, but employees hired after that date accrue 15 days per year for the first nine years 
of employment and 21 days per year thereafter. Most states placed no limit on the amount of sick 
leave that could be accumulated; those that did (nine states) most often limited accumulated leave 
to between 90 and 150 days. 
The Workplace Economics, Inc., study also indicated that 45 states provided some form of 
compensation for unused sick leave at retirement.43 However, in May 2009, CRS determined that 
one additional state (Maine) also provided compensation for unused sick leave. These 46 states’ 
compensation plans generally fell into three categories: 
•  states that provided employees with a cash payment for some portion of their 
unused sick leave, 
•  states that provided service credit for the leave in the computation of retirement 
annuity, or 
•  states that used the unused sick leave to fund some type of health or life 
insurance for retirees. 
The type and amount of compensation provided varied substantially within these three categories, 
and in some cases the states provided employees with options across the categories (e.g., allowing 
employees to choose either service credit for annuities or health insurance payments), or provided 
more than one form of compensation. For example, in Nevada, employees were paid for unused 
sick leave of more than 30 days to a maximum of $8,000. In addition, Nevada state employees 
could receive compensation for 50% of the hours in a special sick leave account as either a lump 
sum payment, advanced payment of an insurance premium, or to purchase additional service 
credit.44 
Cash Payment Plans 
In 28 states, retirees were provided a cash payment for a portion of their unused sick leave. In 
each of these states, the size of the payment was limited in some way—for example, paying 
employees for a percentage of their final sick leave balance (most commonly 25% or 50%), 
capping the number of days or hours of sick leave payable or the size of the payment itself, or 
calculating the size of the payment based on a formula. In many cases, the states used a 
combination of these or other factors in determining the amount payable. For example: 
                                                             
43 The five states that the study said provided no compensation for unused sick leave were Alaska, Indiana, Maine, 
Oregon, and Vermont. In Vermont, though, a limited number of employees are covered by a retirement plan in which 
50% of unused sick leave is added to an employee’s average final compensation. Also, CRS determined in May 2009 
that Maine provides up to three months of service credit for unused sick leave at the time of retirement. 
44 After accruing 90 days of sick leave, Nevada state employees could carry over 50% of unused sick leave each year in 
a special account to be used for long-term illnesses.

Sick Leave 
 
•  In Virginia state employees were paid for 25% of their unused sick leave with the 
amount of the payment capped at $5,000. 
•  In New Hampshire employees were paid for 33% of their unused sick leave up to 
40 days. 
•  Arkansas used a combination of a formula and a cap on the size of the payment: 
employees with less than 50 days of unused sick leave on the date at retirement 
received no payment, employees with 50 to 59 days were paid for 50% of their 
sick days at 50% of their salary, with the scale gradually rising to where 
employees with 80 to 120 days of unused sick leave received payment for 80% of 
their sick days at 80% of their salary. The maximum payment for unused sick 
leave was $7,500. 
In some states, other limits were placed on whether and, if so, how much compensation would be 
provided to their employees for unused sick leave. For example, in Illinois, unused sick leave 
earned by state employees from January 1, 1984, through December 31, 1997, was paid at 50% of 
its value at separation. In Michigan, only retiring employees hired before October 1, 1980, were 
compensated; they received payment for 50% of their unused sick leave based on their last rate of 
pay. 
Service Credit Plans 
In 15 states, employees received service credit for unused sick leave in computing retirement 
benefits (as is currently done for CSRS employees in the federal government), but several states 
placed conditions or limits on the use of sick leave in this manner. For example, in Georgia, 
unused sick leave could be used to compute retirement benefits only if the combined balance of 
sick and annual leave at retirement totaled 120 hours. In Oklahoma, a maximum of one year 
service credit was allowed, but any credited service of six months or more was rounded up to a 
full year. In South Carolina, employees could convert up to 90 days of sick leave to retirement 
service credits, thereby adding up to 4.5 months of service time in calculating the size of their 
annuity. In Maine, retiring employees could receive up to three months of service credit for 
unused sick leave. 
Insurance Plans 
In seven states, the value of some portion of unused sick leave could be credited toward retiree 
health or life insurance premiums. For example, in Utah, retirees could use unused sick leave to 
purchase health insurance, with eight hours of sick leave equal to one month of individual 
coverage. As in the previous categories of compensation, states often placed limits on the use of 
sick leave in this manner. For example, in Idaho, half of the monetary value of unused sick leave 
earned since July 1, 1976, or 600 hours (whichever is smaller), could be used to pay the retiree’s 
premiums for group health programs.

Legislative Developments 
110th Congress 
On March 10, 2008, Representative Jim Moran introduced H.R. 5573, which would have 
compensated employees under FERS and the Foreign Service Retirement System for a portion of 
their unused sick leave at the time of retirement. Specifically, the legislation would have 
permitted employees45 who satisfied the age and service requirements for immediate or early 
retirement in those systems to receive a lump-sum payment equal to 15% of the hourly rate of 
their basic pay for each hour of unused sick leave balance over 500 hours, with the total payment 
capped at $10,000. For example, an employee with a salary of $75,000 (i.e., $35.90 per hour) and 
a sick leave balance of 1,250 hours at the time of retirement could have received about $4,000 for 
her unused sick leave in excess of 500 hours (i.e., 750 hours times $35.90 per hour times 0.15 = 
$4,039). The legislation indicated that the payment “shall be payable by the agency from which 
the employee was separated,” and “shall be considered pay for taxation purposes only” (e.g., not 
for purposes of calculating an employee’s “high three” average salary in determining her 
pension). H.R. 5573 was referred to the House Committee on Oversight and Government 
Reform’s Subcommittee on the Federal Workforce, Postal Service, and the District of Columbia, 
but saw no further action during the 110th Congress. 
Representatives from the Federal Managers Association supported the measure, saying it would 
discourage many federal employees from taking unnecessary sick days.46 The bill was also 
supported by the National Treasury Employees Union as “a reasonable and welcome step to 
correct some of the disparity in treatment for FERS retirees.”47 However, one FMA local 
president said the bill did not go far enough, and that “People are going to keep burning their 
leave until [Congress] provides a better program.”48 An OPM official reportedly remained 
cautious about whether differences in sick leave usage rates between FERS and CSRS employees 
would be addressed by the legislation.49 
On July 30, 2008, the House of Representatives passed the Family Smoking Prevention and 
Tobacco Control Act (H.R. 1108), and the legislation was referred to the Senate on August 1, 
2008. Section 407 of the bill, as amended, would have permitted FERS employees to receive 
service credit in the computation of their annuities for any unused sick leave they had at the time 
of retirement—just as CSRS employees are currently able to do (although FERS employees 
                                                             
45 The bill defines “employee” to mean an employee as defined in 5 U.S.C. 2105, and also includes employees of the 
U.S. Postal Service and the Postal Regulatory Commission, but does not include a congressional employee as defined 
in 5 U.S.C. 2107.

would have received only a 1% increase in their annuities for each additional year of service, not 
the 2% that CSRS employees receive). To phase in the program, those who retired in the first 
three years after the bill was enacted would have received credit for only 75% of their unused 
sick leave. Representative Moran reportedly said that the bill would cost $70 million in the first 
five years, and $337 million in the first 10 years.50 The Federal Managers Association and the 
National Treasury Employees Union expressed support for the bill.51 However, neither H.R. 1108 
nor the related Senate bill (S. 625, which did not contain the sick leave provision) was enacted 
before the end of the 110th Congress. 
111th Congress 
On February 10, 2009, Representative Moran introduced H.R. 958, which would permit FERS 
employees to receive service credit in the computation of their annuities for any unused sick leave 
they had at the time of retirement. Although similar in that respect to Section 407 of H.R. 1108 in 
the 110th Congress, H.R. 958 does not have the phase-in provision that was in the previous 
legislation. The proposed legislation, which was referred to the House Committee on Oversight 
and Government Reform, would apply to any FERS employee who retires under a basic or early 
retirement annuity after the date of enactment. Several federal employee organizations (e.g., the 
American Federation of Government Employees, Federally Employed Women, and the National 
Association of Active and Retired Federal Employees) immediately announced their support for 
the legislation.  
Similar provisions were included in H.R. 1256, the Family Smoking Prevention and Tobacco 
Control Act, which was introduced by Representative Henry Waxman on March 3, 2009, and was 
reported by both the House Committee on Energy and Commerce and the House Committee on 
Oversight and Government Reform on March 26, 2009. In the Energy and Commerce committee 
report on the legislation, the Congressional Budget Office estimated that an average of about 
three months would be added to employees’ length of service, which was estimated to increase 
the average retirement benefit by about $150 per year. As a result, aggregate spending was 
estimated to increase over the 2010 through 2019 period by about $600 million.52 On April 2, 
2009, H.R. 1256 was passed by the House and received in the Senate. The next day it was placed 
on the Senate legislative calendar. However, the FERS sick leave provisions were not included in 
the final legislation (P.L. 111-31).  
National Defense Authorization Act 
The House-passed version of the National Defense Authorization Act for FY2010 (H.R. 2647) 
contained the FERS sick leave provisions, but the Senate-passed version (S. 1390) did not. 
According to press accounts, on October 7, 2009, House and Senate conferees agreed to include 
the sick leave provisions in the final legislation, but to phase in the service credit over four years 
(with 50% credit for unused sick leave until December 31, 2013, and 100% credit starting on

January 1, 2014).53 On October 8, 2009, the House of Representatives agreed to the conference 
report (H.Rept. 111-288) to H.R. 2647, which contained the FERS sick leave provision in Section 
1901 of the General Provisions.54 The Senate agreed to the conference report on October 22, 
2009, and the President signed the legislation on October 28, 2009 (P.L. 111-84).  
Effects of the Change in Policy on FERS Annuities 
The amount of increased annuity that FERS employees will receive as a result of this change in 
policy depends on three factors: (1) the amount of unused sick leave they have at the time of 
retirement, (2) their “high-three” average salary at the time of retirement, and (3) whether they 
retire before or after January 1, 2014. 
Table 5 below provides estimates of the increase in annuity 
at various high-three average salaries for employees who retire before 2014. For example, a 
FERS employee with a high-three average salary of $80,000 and a sick leave balance at 
retirement of 1,000 hours would receive an increase in his or her annuity of about $192 per year.55 
With a FERS annuity of $24,000 per year ($80,000 times 0.1 times 30),56 the $192 represents an 
annuity increase of about 0.8%. Over a 20-year retirement, the 1,000 hours of unused sick leave 
represents at least $3,840 in additional income ($192 per year times 20 years).57

Notes: Service credit for unused sick leave is provided only for ful  months, but employees may add to their sick 
leave service credit through regular service to reach an additional month. For example, an employee with 500 
hours of sick leave would be eligible for two months and 26 days of service credit, but the employee could work 
an additional four days to reach three months. The estimates in the table assume employees will do so.

proportion that 1,000 hours is of a full work year of 2,087 hours) times 0.5 (the 50% credit for unused sick leave until

Table 6 provides estimates of the increase in annuity at various high-three average salaries for 
employees who retire after 2014. For example, a FERS employee with a high-three average salary 
of $80,000 and a sick leave balance at retirement of 1,000 hours would receive an increase in his 
or her annuity of about $383 per year.58 With a FERS annuity of $24,000 per year ($80,000 times 
0.1 times 30),59 the $383 represents an annuity increase of about 1.6%. Over a 20-year retirement, 
the 1,000 hours of unused sick leave represents at least $7,660 in additional income ($383 per 
year times 20 years).60

Appendix. State Sick Leave Policies 
Unless otherwise indicated, the following information on sick leave policies in state government 
is drawn from the 
2004 State Employee Benefits Survey, published by Workplace Economics, Inc. 
The data are as of January 1, 2004. Where more than one accrual rate or maximum accumulation 
is listed, the rate depends on length of service or other factors. An asterisk (*) indicates that there 
are additional or qualifying details in the survey. For example, in Colorado, employees are 
generally limited to 45 days maximum leave accumulation, but employees hired before July 1, 
1988, are limited to their accrual as of that date plus 45 days.
