WARN Act Layoff Notice: What 60 Days' Warning Means for Employees: key takeaways

A visual summary of this post's main points. Read the article for context and limits.

Key point 1
The federal WARN Act generally covers employers with 100 or more employees, not counting part-time workers
Key point 2
Notice is due 60 calendar days before a plant closing or mass layoff, and it goes to affected workers, their union, the state, and local government
Key point 3
An employer that skips notice can owe back pay and benefits for each day of the violation, up to 60 days

A layoff announced on a Friday with a final paycheck the next week can leave a worker with no time to plan. For many large employers, federal law requires far more warning. The Worker Adjustment and Retraining Notification Act, usually called the WARN Act, requires advance written notice of certain plant closings and mass layoffs so workers and their communities can prepare.

Which Employers the WARN Act Covers

The federal rule generally applies to private employers with 100 or more employees, not counting workers who have been employed fewer than six months or who work fewer than 20 hours a week. It also reaches employers with 100 or more employees who together work at least 4,000 hours a week. Public and quasi-public entities that operate separately from the government can be covered too, while regular federal, state, and local government units are not.

What Counts as a Plant Closing or Mass Layoff

Plant closing
A permanent or temporary shutdown of a single site, or of one or more operating units within a site, that causes an employment loss for 50 or more employees during any 30-day period.
Mass layoff at a single site
A reduction in force that is not a plant closing but causes an employment loss during a 30-day period for at least 500 employees, or for 50 to 499 employees if they make up at least 33 percent of the employees at that site.
Employment loss
A termination other than for cause, a layoff of more than six months, or a reduction in hours of more than 50 percent in each month of a six-month period.
Layoffs over time
Smaller job cuts at one site can be added together over a 90-day period, so an employer cannot avoid the notice rule by splitting a layoff into small rounds.

Who Must Receive the 60-Day Notice

The employer must give written notice at least 60 calendar days before the closing or layoff. Notice goes to each affected employee, or to their union representative if they are represented, and also to the state dislocated worker unit and the chief elected official of the local government. Part-time workers are not counted toward the coverage thresholds, but they are still entitled to notice when their jobs are affected.

When an Employer May Give Less Notice

The law allows shorter notice in limited situations, including a faltering company that was actively seeking financing, unforeseeable business circumstances, and natural disasters. An employer that relies on one of these exceptions must still give as much notice as is practicable and explain in the notice why it is giving less than 60 days. A general claim that business was slow rarely settles the question, so the stated reason deserves a close look.

What an Employer Can Owe if Notice Was Not Given

An employer that violates the notice rule can be liable to each affected employee for back pay and the value of lost benefits for each day of the violation, up to a maximum of 60 days. Pay already given in place of notice can reduce the amount. The Department of Labor does not bring WARN lawsuits itself, so a worker who believes notice was required generally has to pursue the claim in court. Because the law has no deadline of its own, courts borrow a state limitation period, which can be short.

State Notice Laws May Offer More

Several states have their own layoff notice laws. Some apply to smaller employers, cover smaller layoffs, or require longer notice than the federal rule. If you worked in a state with its own law, both laws may apply, so check the state labor department's guidance alongside the federal rules.

What to Save After a Layoff Announcement

Keep the layoff notice or termination letter and the date and manner in which you received it. Save any earlier announcement, internal email, or meeting invitation about the closing. Note how many coworkers at your site lost their jobs and when. Keep pay stubs, benefit statements, and any severance offer. Do not sign a release without understanding whether it gives up a notice claim. Our guide to severance agreement red flags explains what to check first.

Where to Find Official Guidance

The Department of Labor explains the notice rules on its WARN Act page, and the full regulation is published as 20 CFR Part 639. If you lost your job in a large layoff and think the notice was late or missing, a free consult can help you sort out whether the federal or a state law applies and which deadlines may be running.

Frequently Asked Questions

Does the WARN Act apply to every layoff?

No. It covers employers with 100 or more employees and applies only to plant closings and mass layoffs that meet the federal thresholds. A small layoff at a large company may fall outside the federal rule, though a state law can still apply.

Can my employer pay me instead of giving notice?

Pay in place of notice can reduce what the employer owes, but it does not by itself show that the employer complied. The amount, the benefits included, and the reason notice was short all matter.

Are part-time workers entitled to WARN notice?

Part-time workers are not counted when deciding whether the employer or site is covered, but they are entitled to notice if their jobs are lost in a covered closing or layoff.

What can I recover if my employer did not give notice?

A worker may recover back pay and the value of lost benefits for each day of the violation, up to 60 days, in a lawsuit. The employer may reduce the amount by wages paid during the violation period.

Should I sign a severance release after a mass layoff?

Read it carefully first. A release can waive claims, including a notice claim, so get it reviewed before you sign, especially if the layoff was announced with less than 60 days of warning.
