My employer laid off 200 people in our office but gave only 2 weeks notice. Can I sue under WARN?

If your employer has 100+ employees nationwide and the layoff meets WARN's numerical thresholds — 200 people at one site almost certainly qualifies as a mass layoff — then a 2-week notice instead of the required 60 days is a WARN violation. You may be entitled to up to 58 additional days of back pay and benefits value (60 minus the 2 days of notice provided). WARN claims are typically filed as class actions when hundreds of workers are affected. Consult an employment attorney immediately — the statute of limitations is 3 years, but class certification and discovery take time. Many employment attorneys handle WARN cases on contingency because the damages can be calculated precisely.

My company has 85 employees. Does the federal WARN Act protect me?

The federal WARN Act's 100-employee threshold means your employer is not covered by the federal law. However, check your state's mini-WARN law — several states cover smaller employers. California's Cal-WARN applies to employers with 75+ employees; New York's NY WARN covers 50+; Illinois's law covers 75+ full-time employees. If you're in one of those states, your employer may owe you notice even though the federal WARN Act doesn't apply. Contact your state's workforce agency or an employment attorney to determine which state law applies to your situation.

I received a WARN notice saying my plant is closing. Does that mean I'll definitely be laid off?

A WARN notice means the employer is legally notifying you of an anticipated closure or layoff — it does not mean the action is certain. WARN allows employers to update and even rescind notices if circumstances change before the action takes effect. However, receiving a WARN notice is a strong signal that your employer believes the event is likely. Use the 60-day notice period to begin your job search immediately, research your unemployment benefits, review any severance offer, and evaluate COBRA continuation coverage for your health insurance. The 60 days of advance notice is legally required to give you exactly this preparation time.

My employer says they didn't need to give WARN notice because of an "unforeseeable business circumstance." Is that right?

The unforeseeable business circumstance exception is narrowly interpreted by courts. The exception applies only when the plant closing or mass layoff is caused by a business circumstance that was not reasonably foreseeable at the time the 60-day notice would have been required. Losing a major customer, a sudden market crash, or an unexpected contract cancellation can qualify — but the employer must demonstrate that the event was sudden, dramatic, and outside their reasonable prediction. General economic downturns, declining sales over months, or industry-wide contractions typically do not qualify because a reasonable employer would have seen them coming. If your employer claims this exception and you believe it's a stretch, consult an employment attorney.

My employer filed for bankruptcy and laid everyone off immediately with no WARN notice. What can I do?

WARN Act claims survive bankruptcy — they become priority unsecured claims in the bankruptcy proceeding. File your WARN claim with the bankruptcy court, not with the NLRB or federal district court (unless the bankruptcy is dismissed). WARN Act wages (back pay) may receive priority treatment under the Bankruptcy Code, which means WARN claimants may recover ahead of general unsecured creditors. Your state's workforce agency may also have rapid response services for workers affected by sudden business closures, including emergency information about UI filing. Act quickly — bankruptcy deadlines for filing claims (proof of claim) are typically 70-90 days from the bankruptcy petition date or the claims bar date set by the court.

WARN Act: Federal Law on Mass Layoff Notice Requirements

The WARN Act entitles workers to 60 days notice before mass layoffs. Violations can mean up to 60 days of back pay. Here is the full federal law explained.

The federal WARN Act requires employers with 100 or more employees to give workers 60 days of written advance notice before a plant closing or mass layoff — a right that translates to up to 60 days of back pay and benefits if an employer violates it, enforceable through federal court class actions.

Key Takeaways

WARN covers employers with 100+ full-time employees. Covered events: plant closings affecting 50+ workers, or mass layoffs affecting 500+ workers (or 50-499 if that's 33%+ of the workforce at the site).
Violation remedy: up to 60 days of back pay plus 60 days of lost benefits value per affected worker, plus civil penalties up to $500/day for failure to notify local government.
26 states have their own "mini-WARN" laws with lower thresholds or longer notice periods. California (75 employees, 60 days), New York (50 employees, 90 days), and New Jersey (100 employees, 90 days) are the most expansive.

Who the WARN Act Covers

The federal WARN Act (Worker Adjustment and Retraining Notification Act, enacted 1988) applies to employers with 100 or more full-time employees — specifically, those working 20+ hours per week for 6+ months. Part-time workers below that threshold don't count toward the 100-employee trigger. The 100-employee count applies across the entire company for plant closings but uses the affected site count for mass layoff thresholds. WARN covers private sector employers; most federal, state, and local government entities are exempt from the federal law (though state mini-WARN laws vary on this).

What Triggers a Notice Requirement

Two events trigger WARN obligations at covered employers: a plant closing — the temporary or permanent shutdown of a single employment site affecting 50 or more workers — or a mass layoff — a reduction in force that doesn't involve a plant closing but affects either 500+ workers at a single site, or 50–499 workers if they represent at least 33% of the total active workforce at that site. Temporary layoffs expected to last more than 6 months trigger the same notice obligation as permanent separations. Transfers within the company to another site more than 50 miles away also count.

What the 60-Day Notice Must Include

WARN notices must be in writing and go to three parties: each affected worker or their union representative, the state's dislocated worker unit (typically the state's workforce agency), and the chief elected official of the local government (mayor, county executive) where the layoff occurs. The notice must specify the expected date of the first separation, the anticipated schedule of separations, whether the action is expected to be temporary or permanent, bumping rights if applicable, and the name and phone number of the company official handling the action. Generic emails to all-staff without individual notice don't satisfy WARN.

Exceptions That Reduce or Eliminate the 60-Day Requirement

Three narrow exceptions allow shorter notice — but the employer still must give as much notice as practicable and explain in writing why full notice wasn't possible: the faltering company exception (actively seeking financing that would have been jeopardized by a WARN notice); unforeseeable business circumstances (a sudden, dramatic market change that a reasonable employer could not have predicted, such as the abrupt loss of a major customer); and natural disaster (flooding, earthquake, or similar event that directly caused the plant closing or layoff). Courts have consistently narrowed these exceptions — employers frequently invoke them and lose in litigation.

Remedies When an Employer Violates WARN

An employer who fails to give adequate WARN notice owes affected workers up to 60 days of back pay (at their regular rate) plus the value of benefits — health insurance premiums, 401(k) contributions, vacation accrual — for up to 60 days. Severance already paid offsets this liability dollar-for-dollar. Employers also face civil penalties up to $500 per day for failure to notify local government. WARN claims are filed in federal district court and commonly proceed as class actions when an employer's mass layoff affects hundreds of workers. The statute of limitations is typically 3 years from the violation date.

State Mini-WARN Laws

Twenty-six states and the District of Columbia have enacted state-level WARN equivalents, many with lower thresholds or longer notice periods than the federal law. The most significant: California (Cal-WARN) covers employers with 75+ employees, requires 60 days notice, applies to seasonal employers with no July–January exemption, and expressly covers mass layoffs of 50+ workers regardless of percentage; New York (NY WARN) covers employers with 50+ full-time employees and requires 90 days notice — 50% longer than the federal requirement; New Jersey requires 90 days notice and mandates severance pay for covered layoffs (one week per year of service). If federal WARN doesn't apply because your employer has fewer than 100 employees, your state's law may still require notice.
