WARN Act Layoff Notice Rights: When 60 Days' Notice May Be Required
Federal WARN Act notice rules can apply to certain plant closings and mass layoffs. Learn about employer and layoff thresholds, exceptions, and records to save.
When Does the WARN Act Require Layoff Notice?
The federal Worker Adjustment and Retraining Notification Act can require a covered employer to give 60 calendar days' written notice before a covered plant closing or mass layoff. It does not apply to every termination, reduction in force, or business closure. Employer size, the number and percentage of job losses, the single site of employment, timing, worker status, transfers, and any claimed exception all affect whether notice was required.
Employer Size and Layoff Thresholds Matter
A business is generally covered if it has at least 100 employees excluding workers whom WARN defines as part time, or at least 100 employees including part-time workers who together work at least 4,000 hours per week excluding overtime. A plant closing generally requires 50 or more covered employment losses at one site within 30 days. A mass layoff generally requires 50 to 499 covered losses that are at least one-third of the active workforce at the site, or 500 or more covered losses without the one-third test.
Count the Site, Timing, and Type of Job Loss
WARN usually measures job losses at a single site of employment. Employment loss can include a termination other than a discharge for cause, voluntary departure, or retirement; a layoff expected to exceed six months; or a reduction in hours of more than 50 percent in each month of a six-month period. Separate reductions may need to be counted together across 30-day or 90-day periods. Save site assignments, reporting locations, headcounts, layoff lists, dates, hours, transfer offers, and explanations for grouping or separating the affected workers.
What Should a WARN Notice Tell an Employee?
An unrepresented affected employee should receive understandable written notice stating whether the action is expected to be permanent or temporary, the expected date of the closing or layoff and the employee's separation, whether bumping rights exist, and a company contact for more information. If workers are represented, notice generally goes to their representative. Separate notice also goes to the state dislocated worker unit and the appropriate local government official. A general announcement or ordinary bulletin-board posting is not the same as individual written notice.
Exceptions May Reduce Notice, Not Erase the Explanation
WARN recognizes limited grounds for less than 60 days' notice, including certain unforeseeable business circumstances and natural disasters. A narrowly construed faltering-company exception can apply to some plant closings but not mass layoffs. The employer bears the burden of showing an exception applies and still must give as much notice as practicable. A shortened notice should explain why the notice period was reduced, so preserve the notice, envelopes or delivery records, later updates, and the employer's stated timeline.
Part-Time, Remote, and Leave Status Can Change the Count
Workers classified as part time under WARN are generally not counted toward the plant-closing or mass-layoff thresholds, but they are still due notice when they are affected by a covered event. Workers on leave may also be due notice when they have a reasonable expectation of returning. For remote or traveling workers, the single site may be the location used as a home base, the location from which work is assigned, or the location to which the worker reports. These rules are fact-specific, so keep schedules, tenure records, leave documents, remote-work assignments, and reporting lines.
What If Required Notice Was Missing or Late?
Affected workers or their union may bring a federal court action under WARN. Potential relief can include back pay and benefits for the violation period, up to 60 days, subject to statutory rules and possible reductions. The U.S. Department of Labor provides compliance information but does not investigate or enforce individual WARN claims. State plant-closing laws may cover different employers, events, or notice periods, so do not assume the federal threshold answers every state-law question.
When to Get a Free Consult
Get a free consult if a large layoff or closing happened with no written notice, less than 60 days' notice, shifting explanations, separated rounds of job losses, disputed worker counts, or an unexpected benefit cutoff. Seek review promptly because rights depend on employer coverage, the site and timing of losses, worker status, notice contents, exceptions, remedies, deadlines, and state law.
