Worker Adjustment and Retraining Notification (WARN) Act 
 
Summary 
Enacted by the 100th Congress, the Worker Adjustment and Retraining Notification (WARN) Act 
requires qualified employers that intend to carry out plant closings or mass layoffs to provide 60 
days’ notice to affected employees, states, and localities. The purpose of the notice to workers is 
to allow them to seek alternative employment, arrange for retraining, and otherwise adjust to 
employment loss. The purpose of notifying states and localities is to allow them to promptly 
provide services to the dislocated workers and otherwise prepare for changes in the local 
labor market. 
The WARN Act applies to employers with at least 100 or more full-time employees or 
equivalents. Federal, state, and local government employers are not subject to the act.  
Broadly speaking, there are three types of events that require notification under the WARN Act. 
Each of these events is limited to a single site of employment; employment losses by a single 
employer across multiple sites are not aggregated. Events that trigger the requirements of the 
WARN Act are 
•  a plant closing resulting in employment losses of at least 50 employees; 
•  a mass layoff of at least 50 employees where the employment loss consists of at 
least 33% of employment at the site; or 
•  a mass layoff with an employment loss of 500 or more at a single site of 
employment, regardless of its proportion of total employment at the site or if the 
employment loss is part of a plant closing. 
For the purposes of the WARN Act, an employment loss is defined as an involuntary termination, 
layoff exceeding six months, or a reduction in hours worked exceeding 50% for each of six 
consecutive months. In addition to the three events described above, an employer may also be 
subject to the WARN Act if it engages in several layoffs during a 90-day period that, in aggregate, 
meet the criteria of an applicable event. Short-term layoffs that are later extended to six months or 
more may also trigger WARN Act requirements. 
The act and accompanying regulations also specify situations in which an otherwise covered 
employer may be exempt from WARN Act requirements. Generally, these exceptions relate to 
unanticipated situations such as unforeseeable business circumstances or natural disasters. 
The WARN Act is enforced through the federal court system. While the Department of Labor is 
permitted to establish regulations related to the act and offer non-binding guidance to employers 
and workers, all penalties and settlements are administered through the courts.

Worker Adjustment and Retraining Notification (WARN) Act 
 
Background and Purpose 
The Worker Adjustment and Retraining Notification (WARN) Act requires qualified employers 
that intend to carry out plant closings or mass layoffs to provide 60 days’ advance notice to 
affected employees, states, and localities. There are several purposes to the WARN Act. Notices 
provide workers with time to seek alternative employment, arrange for retraining, and otherwise 
adjust to the prospect of employment loss. The act also provides notice to state dislocated worker 
units so that services can be provided promptly to the affected employees and to local 
governments so they can adjust to upcoming changes in their local labor market. 
Although “retraining” appears in its title, the WARN Act does not authorize or fund training 
activities. Workers affected by layoffs covered by the WARN Act may be eligible for training 
services under the dislocated worker provisions of the Workforce Investment Act (WIA) or, if 
their job loss is attributable to foreign competition, Trade Adjustment Assistance for Workers 
(TAA).1 
Legislative History 
Legislation related to the notification of workers prior to mass layoffs and plant closings was first 
introduced at the federal level in 1973.2 The issue proved to be contentious and more than a 
decade elapsed before Congress enacted the WARN Act (P.L. 100-379) in 1988 without President 
Ronald Reagan’s signature.3 The law became effective in February 1989. Except for some small 
changes to align the WARN Act with terminology changes elsewhere in law, the WARN Act has 
not been amended. 
Most recent proposals related to the WARN Act have proposed expanding the law’s breadth or 
otherwise increasing employer responsibilities. The most recent amendment to the act to come up 
for a vote was in the 110th Congress, when the House passed H.R. 3920, the Trade and 
Globalization Assistance Act of 2007.4 Among other labor provisions, the bill would have 
increased the notice period under the WARN Act from 60 to 90 days and required employers to 
inform the Secretary of Labor of their intended layoffs.

System, by David H. Bradley. For more information on TAA, see CRS Report R42012, Trade Adjustment Assistance 
for Workers, by Benjamin Collins. 
2 The Trade Act of 1974 (Title II, Section 283 of P.L. 93-618) asked firms that planned to move operations outside the 
United States to provide at least 60 days advance notice to employees likely to be adversely affected by their actions as 
well as to the Secretaries of Labor and Commerce.

S. 2527, 100th Congress, Worker Adjustment and Retraining Notification Act, P.L. 100-379, 100th Cong., 2nd sess., 
serial no. 101-K (Washington, DC: GPO, 1990). 
4 After passing the House, the bill was referred to the Senate Committee on Finance, where no action was taken.

Worker Adjustment and Retraining Notification (WARN) Act 
 
Provisions of the WARN Act 
The WARN Act requires covered employers to provide 60 calendar days’ notice prior to qualified 
employment losses of 50 or more.5 The key provisions of the act are described below and at Title 
29, Chapter 23 of the U.S. Code (29 U.S.C. 2101-2109). 
Covered Employers 
To be subject to the WARN Act, employers must have at least 100 full-time employees or 100 or 
more employees who work for at least a total of 4,000 hours per week (exclusive of overtime). 
Persons who are temporarily laid off or are on leave but have a reasonable expectation of being 
recalled are also covered and counted toward the employer-size threshold. The statute and 
regulations offer guidance on defining employers and determining if subsidiaries and independent 
contractors are separate from a parent company.6 
Federal, state, local, and federally recognized tribal governments are not subject to the WARN 
Act. However, public and quasi-public entities that engage in business and that function 
independently of those governments are covered if they meet the employer-size threshold. 
Covered Events 
Broadly speaking, there are three types of events that require notification under the WARN Act. 
Each of these events is limited to a single site of employment; employment losses by a single 
employer across multiple sites are not aggregated. Events that trigger the requirements of the 
WARN Act are 
•  a plant closing resulting in employment losses of at least 50 employees;7  
•  a mass layoff of at least 50 employees where the employment loss consists of at 
least 33% of employment at the site; or 
•  a mass layoff with an employment loss of 500 or more at a single site of 
employment, regardless of its proportion of total employment at the site or if the 
employment loss is part of a plant closing. 
For the purposes of the WARN Act, employment losses are defined as involuntary separations of 
workers exceeding six months or a reduction in hours worked of at least 50% during each month 
for a six-month period.8 Any employment losses during a 30-day period are considered a single 
event for the purposes of the WARN Act. 
                                                 
5 Some states have developed standards that are stricter than the federal WARN Act. These standards may increase the 
period of notice, cover smaller employers, or cover layoffs of fewer than 50 workers. 
6 For complete details on covered employers, see 29 U.S.C. §2101(a)(1) and 20 C.F.R. §639.3. For information on the 
treatment of subsidiaries and independent contractors, see 20 C.F.R. §639.3(a)(2). 
7 A plant closing is defined as the shutdown of a single site of employment or one or more facilities or operating units 
within a single site of employment. See 29 U.S.C. §2101(a)(2).

Worker Adjustment and Retraining Notification (WARN) Act 
 
There are also circumstances in which the WARN Act can be applied retroactively: 
•  If an employer announces layoffs that are for less than six months but otherwise 
meet the WARN Act criteria and then subsequently extends the layoffs past six 
months, the employer may be subject to WARN Act notification responsibilities. 
Unless the employer can establish that the layoff extension was due to 
circumstances that were unforeseeable at the time of the original layoff, the case 
is treated as if notice was required for the original layoff.9 
•  If an employer engages in a series of layoffs that are below WARN Act levels, 
they may be aggregated for up to 90 days unless the employer can establish that 
each layoff was due to distinct, unrelated events. In the case of smaller layoffs 
adding up to a WARN-required level, each employee must receive notice 60 days 
prior to his or her date of termination.10 
Covered Employees 
Employees covered by the statute include hourly and salaried employees, managers, and 
supervisors on the employer’s payroll. The law does not apply to an employer’s business partners, 
contract employees who have an employment relationship with and are paid by another employer, 
and self-employed individuals. 
Part-Time Employees 
Part-time employees are defined as persons who work on average fewer than 20 hours per week 
or who have been employed fewer than 6 of the 12 months preceding the date on which notice is 
required. Part-timers thus include recently hired employees working full-time hours and seasonal 
(part-year) workers. Although part-time employees are not counted toward the threshold for 
determining employer coverage under the law, they nonetheless are due advance notice from 
covered employers. 
Employees Not Entitled to Notice 
Employees who are counted toward the firm-size threshold but are not entitled to advance notice 
include U.S. workers who are located at an employer’s facility in a foreign country and 
individuals who are clearly told upon being hired that their employment is temporary (e.g., 
limited to the time it takes to complete a specific project). 
Notification Requirements 
Written notice of WARN events must be provided to each affected employee 60 calendar days 
prior to layoff.11 If the affected employees are covered by a collective bargaining agreement, 
notification can instead be issued through the employees’ bargaining representative.  
                                                 
9 See 29 U.S.C. §2102(c). 
10 See 29 U.S.C. §2102(d).

Worker Adjustment and Retraining Notification (WARN) Act 
 
In addition to the affected employees or their representative, an employer must notify the state 
entity responsible for carrying out rapid response activities12 and the chief elected official of the 
local government within which the layoffs are to occur.13 
The required content of the notifications varies somewhat depending on whether they are being 
issued to employees, union representatives, or government entities.14 All notifications must 
include (1) a description of the planned action and a statement as to whether the planned action is 
expected to be permanent or temporary, (2) the expected date or dates when the layoffs will 
commence,15 and (3) the name and telephone number of a company official to contact for 
more information. 
Bumping Rights 
In some cases, company policy or a collective bargaining agreement may permit bumping rights. 
Typically, bumping rights allow a more senior employee whose job is eliminated to replace 
(bump) a less senior worker whose job was not eliminated. Under bumping rights, it is possible 
that the worker who is ultimately laid off is not the worker whose job was eliminated. 
In cases where a workplace has bumping rights but workers are not covered by a collective 
bargaining agreement, the employer must attempt to identify the worker who will ultimately be 
terminated subsequent to bumping and provide him or her with notice. If the employer is not able 
to reasonably identify the worker who will ultimately be laid off, notice can be issued to the 
incumbent worker whose job is being eliminated. 
In cases where bumping rights exist, the affected employees are covered by a collective 
bargaining agreement, and notice is issued to an employee representative rather than the 
employees themselves, it is not necessary for the employer to identify the ultimate bumpees. 
Instead, the employer’s notice to the employee representative must identify the specific positions 
that will be eliminated. In these cases, the workers’ representative is responsible for identifying 
and notifying the ultimate bumpee. 
Enforcement and Penalties 
The U.S. Department of Labor does not have any investigative or enforcement authority under the 
law. It is authorized to write regulations and provide assistance in understanding them. 
                                                                  
(...continued) 
loss as a consequence of a proposed plant closing or mass layoff[.]” See 29 U.S.C. §2101(a)(5). 
12 Rapid response activities are state-administered services to dislocated workers following a mass layoff. Services 
include, but are not limited to, career counseling, job search assistance, education and training services, and access to 
unemployment insurance. 
13 See 29 U.S.C. §2102(a). 
14 Complete requirements for each notice are at 20 C.F.R. §639.7. 
15 The date may be a specific day, a schedule of layoffs, or a 14-day period in which separations are expected to occur. 
In cases where an employer provides a 14-day period in which layoffs are expected to occur, notice must be issued 60 
days prior to the beginning of the 14-day period. See 20 C.F.R. §639.7(b) for further details.

Worker Adjustment and Retraining Notification (WARN) Act 
 
The WARN Act is enforced through the federal court system. Employees, their representatives, or 
units of local government can bring civil actions in district court against employers thought to 
have violated the WARN Act. A court does not have the authority to stop a plant closing or 
mass layoff. 
Employers who violate the WARN Act are liable for back pay and benefits (e.g., the cost of 
medical expenses that would have been covered had the employment loss not occurred) to each 
aggrieved employee. The penalty is calculated for each working day that notice was not provided 
up to a maximum of 60 days. In other words, the 60-day liability is reduced for each day that 
notice was provided. Maximum liability may be less than 60 days for those employees who had 
worked for the employer for fewer than 120 days. 
In addition to payments to workers, employers found to be in violation of the WARN Act may 
also be subject to a $500 civil fine for each day fewer than 60 that they provided notice to 
affected employees. An employer can avoid the civil penalty entirely if each aggrieved employee 
is paid the full amount for which the employer is liable within three weeks from the date of the 
plant closing or mass layoff.16 
Exceptions that Allow for a Notice Period of Less Than 60 Days 
The statutory language of the WARN Act specifies three exceptions in which employers may 
provide less than 60 days’ notice to employees and jurisdictions affected by an employment 
loss:17 
•  The faltering company exception: Employers can provide reduced notice for plant 
closings, but not for mass layoffs, if they had been seeking financing or business 
for their faltering enterprises, thought they had a realistic chance of obtaining 
funds or new business sufficient to allow the facilities to remain open, and 
believed in good faith that giving notice would have prevented them from getting 
the capital or business necessary to continue their operations. 
•  The unforeseeable business circumstances exception: Employers can provide 
reduced notice if they could not reasonably foresee the business circumstances 
that caused the plant closings or mass layoffs. Circumstances that occurred 
without warning and that were outside the employer’s control could include (1) a 
major client terminating a large contract with the employer, (2) a strike at a 
supplier of key parts to the employer, or (3) the swift onset of a deep economic 
downturn or a non-natural disaster (e.g., a terrorist attack). 
•  The natural disaster exception: Employers may also provide reduced notice if the 
layoff is due to a natural disaster such as a flood, earthquake, drought, or storm. 
If a plant closing or mass layoff is indirectly due to natural disasters, the 
exception would not apply; however, the unforeseen business circumstances 
exception might.

Worker Adjustment and Retraining Notification (WARN) Act 
 
Other Special Circumstances 
The WARN Act also addresses several special circumstances and the responsibilities of the 
affected parties in each circumstance. 
Transfers or Reassignments 
If a closing or layoff takes place due to the relocation or consolidation of all or part of an 
employer’s business, the plant closing or mass layoff is not considered an employment loss if 
before the action,18 
•  the employer offers to transfer an employee to another site within reasonable 
commuting distance and no more than a six-month break in employment occurs 
(regardless of whether the employee accepts or rejects the offer); or 
•  the employee accepts a transfer to another site—regardless of distance—with no 
more than a six-month break in employment, within 30 days of the employer’s 
offer or of the closing/layoff, whichever is later. 
Strikes and Lockouts 
Plant closings or mass layoffs that are the result of a strike or lockout are exempt from the notice 
requirement unless employers lock out employees to evade compliance with the act.19 “Economic 
strikers” whom employers permanently replace do not count toward the employee-size thresholds 
necessary to trigger the notice requirement.20 Non-striking employees who experience an 
employment loss directly or indirectly associated with a strike and employees who are not 
members of the bargaining unit involved in the contract negotiations that prompted a lockout are 
entitled to advance notice.21 
Temporary Employees 
Temporary employees and other employees associated with projects of limited duration are not 
entitled to notice under the WARN Act so long as the employees were hired with the 
understanding that their employment was limited in duration.22 Regulations state that an 
understanding of temporary employment can be established by “reference to employment 
contracts, collective bargaining agreements, or employment practices of an industry or locality, 
but the burden of proof will lie with the employer.”23 
                                                 
18 See 29 U.S.C. §2101(b)(2). 
19 See 29 U.S.C. §2103(2). 
20 Economic strikers are those employees who go on strike over wages, hours, or other working conditions during 
contract negotiations. 
21 See 20 C.F.R. §639(d). 
22 See 29 U.S.C. §2103(1). 
23 See 20 C.F.R. §639.5(c) for additional details on establishing temporary employment.

Worker Adjustment and Retraining Notification (WARN) Act 
 
Sale of a Business 
The sale of all or part of a business does not in itself produce an employment loss because 
individuals who were employees of the seller through the sale’s effective date are thereafter 
considered employees of the buyer. If a covered plant closing or mass layoff takes place up to and 
including the effective date of the sale, it is the responsibility of the seller to provide notice. If the 
seller knows the buyer has definite plans to initiate a covered plant closing or mass layoff within 
60 days of the purchase, the seller may give notice to affected employees as an agent of the buyer 
if so empowered by the buyer. If not, the buyer becomes responsible for providing the requisite 
advance notice.24 
Notification of Layoffs that Do Not Meet WARN 
Act Criteria 
In addition to establishing criteria and notification procedures for applicable layoffs and plant 
closures, the WARN Act also encourages procedures for layoffs that may not require formal 
notification: 
It is the sense of Congress that an employer who is not required to comply with the notice 
requirements of section 2102 of this title should, to the extent possible, provide notice to its 
employees about a proposal to close a plant or permanently reduce its workforce.25 
Regulations have reiterated and expanded upon this sentiment: 
Notice in ambiguous situations. It is civically desirable and it would appear to be good 
business practice for an employer to provide advance notice to its workers or unions, local 
government and the State when terminating a significant number of employees. In practical 
terms, there are some questions and ambiguities of interpretation inherent in the application 
of WARN to business practices in the market economy that cannot be addressed in these 
regulations. It is therefore prudent for employers to weigh the desirability of advance notice 
against the possibility of expensive and time-consuming litigation to resolve disputes where 
notice has not been given. The Department encourages employers to give notice in all 
circumstances.26 
Neither statute nor regulations discourage or state a penalty associated with notices that are not 
followed by an applicable mass layoff or plant closure. Regulations, however, prohibit employers 
from regularly issuing WARN Act notices so as to perpetually be in compliance with the law in 
the event of a mass layoff or plant closure.27 
                                                 
24 See 29 U.S.C. §2101(b)(1). 
25 See 29 U.S.C. §2106. 
26 See 20 C.F.R. §639.1(e). 
27 Regular issuance of notice is also known as “rolling notice.” See 20 C.F.R. §639.10(b).

WARN Act Notifications and Compliance 
Since the WARN Act does not require firms to notify the federal government prior to layoffs or 
plant closings, there is no central data source for information on WARN Act notifications. As 
such, it is not possible to easily identify how many WARN Act notifications were issued in a 
particular timeframe, nor is there a simple procedure for identifying how many notifications were 
followed by an applicable mass layoff or plant closing. 
In 2003, the Government Accountability Office (GAO; then the General Accounting Office) 
released a report in which it obtained information on WARN notices from state dislocated worker 
units and then matched them to mass layoff and plant closure data from the Bureau of Labor 
Statistics. The report found that of the 5,349 WARN notices issued, only 717 (13%) could be 
matched to a specific mass layoff or plant closing. The report also identified 1,257 additional 
events that appeared to require notification under the WARN Act in which it could not find a 
corresponding layoff notice filed with the state.28
