If your workplace suddenly closed or laid off dozens of people overnight, the WARN Act might have been broken.
The WARN Act is a federal law that requires certain employers to give workers advance notice before a mass layoff or plant closing.
It exists so people aren’t blindsided, left scrambling for a new job with zero warning and zero paycheck coming in.
Not every company falls under it, and not every layoff qualifies, but when it applies, the notice period is not optional.
This page breaks down who’s covered, what counts as a violation, and what you can actually do about it.
By the end, you’ll know whether your employer owed you notice, and what happens next if they skipped it.
Who The WARN Act Covers
The law generally applies to employers with 100 or more full time employees, so small businesses are usually exempt.
It kicks in when a company closes a site affecting 50 or more workers, or lays off a third of the workforce at a location.
The 60 Day Notice Rule
Covered employers must give written notice at least 60 days before a qualifying layoff or closing.
That notice has to go to affected workers, their union if they have one, and local government officials.
Situations That Aren't Covered
Layoffs at small businesses, temporary layoffs under six months, and closures caused by unforeseeable business circumstances can fall outside the rule.
Natural disasters and sudden, unpredictable events sometimes shorten or eliminate the notice requirement entirely.
What Happens If Your Employer Ignores It
Employers who skip the required notice can owe affected workers back pay and benefits for each day of the violation, up to 60 days.
Civil penalties can also apply, which is part of why many companies take this law seriously once they’re caught.
Signs Your Layoff May Have Violated The Law
If you found out about your layoff the same day it happened, that’s the biggest red flag.
Check whether your company has 100 or more employees, since that threshold determines whether the WARN Act even applies to your situation.
Look at how many people were let go at your location. A handful of layoffs won’t trigger it, but a large wave often does.
Compare the date you were told to the date your job actually ended. If it’s a same-day or short-notice situation, you may have a claim.
