The WARN Act: What It Requires and Why It Matters When You're Laid Off
Federal law requires 60 days notice before mass layoffs. Here's what that means for workers, what exceptions employers use, and how to find your company's filings.
If you were part of a mass layoff and your employer gave you less than two months' notice — or none at all — the Worker Adjustment and Retraining Notification Act may entitle you to back pay and benefits for the days you weren't given.
The WARN Act has been federal law since 1988. It requires employers with 100 or more full-time workers to provide at least 60 calendar days' advance written notice before a plant closing or mass layoff. The notice goes to the affected workers, any union representatives, the state dislocated worker unit, and the local government chief elected official.
Most people who are covered by the WARN Act don't know it until after they've been laid off.
When the WARN Act applies
The law covers private-sector employers with 100 or more full-time employees. A qualifying event is either:
- A plant closing: permanent or temporary shutdown of a single employment site that results in employment loss for 50 or more full-time workers during any 30-day period
- A mass layoff: a layoff at a single site that affects either 500 or more workers, or at least 50 workers if they represent at least one-third of the workforce
Part-time workers — those working fewer than 20 hours per week — don't count toward the thresholds for the employer's size or the layoff size. This creates a structuring incentive that many companies have noticed.
More than a dozen states have their own mini-WARN laws with stricter thresholds. California's WARN Act, for example, applies to employers with 75 or more workers (not 100) and uses a lower threshold for what counts as a mass layoff.
What the 60-day notice must include
A valid WARN notice is a written document — not a verbal announcement, not a town hall — that includes:
- The expected date the first layoffs will occur
- Whether the action is expected to be permanent or temporary
- The job classifications of positions to be affected and the number of affected workers in each classification
- The name and contact information of a company official who can provide additional information
The notice goes to three parties simultaneously: individual workers or their union, the state dislocated worker unit, and the chief elected official of the local government where the facility is located. All three must receive it at the same time.
The three exceptions
Employers can give less than 60 days' notice — or no notice — under three narrow statutory exceptions.
The faltering company exception applies when an employer is actively seeking financing that would prevent the shutdown and providing notice would ruin the deal. It's designed for genuine last-ditch financing efforts and is narrow in practice.
The unforeseeable business circumstances exception covers sudden, dramatic changes that a reasonably prudent employer could not have predicted 60 days in advance — a major customer filing for bankruptcy overnight, a government contract cancellation, an unexpected natural disaster. This exception has been applied broadly by some courts and has been stretched by employers accordingly.
The natural disaster exception is for plant closings and layoffs directly caused by a natural disaster.
When an employer invokes an exception, they must still give notice as soon as practicable and explain in writing why less than 60 days was given.
What workers are owed when the law is violated
Employers who violate the WARN Act owe affected workers:
- Back pay for each day of the violation, up to 60 days, calculated at their regular rate of compensation
- The value of benefits they would have received during that period, including health insurance, pension contributions, and any other benefits they were enrolled in
There is also a separate civil penalty of $500 per day per violation to the relevant local government, up to 60 days.
The WARN Act is enforced through private lawsuits — there is no government agency that automatically investigates violations. Workers must bring their own claims in federal district court. Class actions are common because the violation, by definition, affects a large group of workers at once.
How The Separation Index uses WARN data
Every WARN filing becomes a public record maintained by the state labor agency that received it. The Separation Index aggregates these filings and makes them searchable by company, date, state, and worker count.
When you look up a company on The Separation Index, you'll see their WARN history alongside their separation score from confirmed reports. A company that gave full notice on a difficult layoff tells a different story than one that sent workers home the same day the notice was filed.
If you were part of a WARN-covered layoff, submitting a separation report links your anonymized experience to the public record. It helps other workers know what to expect and, over time, creates a dataset of how companies actually handle their obligations — not just whether they technically filed.
