California WARN Act: Your Rights in a Mass Layoff

The meeting invite lands at 8:45 a.m., the badge stops working by noon, and a whole department is gone by the end of the week. When a California layoff happens that fast, the first legal question is not whether the company was allowed to cut jobs — it usually was — but whether it gave you the 60 days' written notice the law requires.

That notice requirement comes from the California WARN Act, and it is one of the few employment laws that pays out based purely on timing rather than on proving the employer had a bad motive.

What the California WARN Act Actually Requires

The California WARN Act (Labor Code sections 1400–1408, often called Cal-WARN) says an employer cannot order a mass layoff, relocation, or plant closure at a covered establishment unless it gives written notice 60 days before the action takes effect.

Three events trigger the notice duty:

• Mass layoff — the separation of 50 or more employees at a covered establishment within a 30-day period because of a lack of funds or lack of work.
• Relocation — moving all or substantially all of the operations to a location more than 100 miles away.
• Termination (closure) — the cessation or substantial cessation of industrial or commercial operations at the establishment.

Notice does not just go to workers. It must also go to the Employment Development Department (EDD), the local workforce development board, and the chief elected official of each city and county where the layoff occurs. The EDD publishes the notices it receives on its WARN information page, which is often the fastest way to confirm whether your employer filed anything at all.

Importantly, Cal-WARN is not limited to permanent job cuts. California courts have applied it to temporary layoffs and furloughs, which means a company cannot dodge the statute by calling a shutdown "temporary."

Which Employers and Employees Are Covered

A covered establishment is an industrial or commercial facility that has employed 75 or more people at any time during the preceding 12 months. That count includes part-time workers. To be entitled to notice, an employee generally must have worked at the establishment for at least 6 of the preceding 12 months.

Cal-WARN vs. the Federal WARN Act

California's version reaches further than the federal WARN Act, so employees sometimes have a state claim even where no federal claim exists:

• Employer size: 75 employees under Cal-WARN, versus 100 under federal law.
• Layoff size: 50 employees under Cal-WARN, with no requirement that they make up a third of the workforce — federal law generally requires 50–499 employees and at least 33% of the site's workforce.
• Cause: Cal-WARN's mass layoff trigger applies whether or not the facility actually closes.

New for 2026: What the Notice Itself Must Say

Effective January 1, 2026, Senate Bill 617 expanded what a Cal-WARN notice must contain. In addition to the information already required, the notice must now include:

1. A statement of whether the employer plans to coordinate services through the local workforce development board, through a different entity, or not at all — and if it is coordinating, those services must be arranged within 30 days of the notice.
2. A description of Rapid Response activities, the state's job-search and retraining help for laid-off workers.
3. An overview of CalFresh, including the benefits helpline and a link to the CalFresh website.
4. A working email address and phone number for both the employer and the applicable local board.

If the notice you received is a bare-bones paragraph with no contact information and no mention of these resources, that is worth flagging to an attorney — the adequacy of the notice, not just its timing, is now squarely in play.

What You Can Recover If Notice Was Skipped

An employer that fails to give proper notice is liable to each affected employee for:

• Back pay at the average regular rate of compensation over the last three years of employment, or the final rate of pay, whichever is higher; and
• The value of lost benefits, including medical expenses the employee incurred that the employer's plan would have covered.

Damages run for the period of the violation, capped at 60 days or one-half the number of days the employee actually worked for the employer, whichever is smaller. Wages and benefits already paid during that window reduce what the employer owes. Labor Code section 1403 adds a civil penalty of up to $500 per day, though an employer that pays everything owed within three weeks of the layoff can avoid it, and section 1404 allows a prevailing employee to recover reasonable attorney's fees.

This is a make-you-whole statute, not a jackpot: for most workers the practical value is a matter of weeks of pay and benefits, often combined with other claims such as an unpaid final paycheck or accrued vacation.

The Exceptions Employers Rely On

Cal-WARN recognizes a narrow set of excuses, and the employer carries the burden of proving one applies:

• A physical calamity or act of war.
• A faltering company that was actively seeking capital or new business and reasonably believed in good faith that giving notice would have prevented it from getting that funding.
• Temporary or seasonal employment, where workers were hired with the understanding the work was for a limited time or a specific project that has been completed.

Courts read these exceptions narrowly. "Business got bad and the board voted on Tuesday" is not, by itself, a defense.

What to Do If You Were Laid Off Without Warning

1. Save everything — the layoff letter, any WARN notice, emails announcing the reduction, your offer letter, and recent pay stubs.
2. Write down the numbers: your last day, the date you were told, roughly how many people were cut, and over what span.
3. Do not rush to sign a severance agreement. Most contain a release that can extinguish a WARN claim; our guide to severance agreement review covers what to look at first.
4. File for unemployment with the EDD right away — that is separate from any WARN claim and does not waive it.
5. Check the deadline. Cal-WARN claims are generally treated as liabilities created by statute, which carries a three-year limitations period, but the deadline that applies to your claim can differ and other wage claims run on shorter clocks. Get it confirmed early rather than assuming.

Frequently Asked Questions

What triggers the California WARN Act?

One of three things at a covered establishment: a mass layoff of 50 or more employees within 30 days, a relocation of operations more than 100 miles, or a closure. Any of them requires 60 days' advance written notice.

How many employees does a company need for the WARN Act to apply?

Under California law, 75 or more employees at the establishment at some point in the prior 12 months, counting part-time staff. The federal WARN Act uses a 100-employee threshold, so a company can be too small for federal WARN and still owe Cal-WARN notice.

Is the WARN Act federal or state law?

Both. The federal WARN Act sets a national floor, and California has its own broader statute. Where they overlap, an employer must satisfy the stricter requirement — and California's usually is.

Does the WARN Act apply to remote workers?

Often, yes. Remote employees are generally counted at the facility they report to or receive assignments from, so a fully distributed team can still be tied to a covered establishment. This area is unsettled, so how your role was structured on paper matters.

How do I report a California WARN Act violation?

No agency adjudicates individual Cal-WARN claims the way the Labor Commissioner handles wage claims — enforcement happens through a civil lawsuit, frequently on behalf of a group of laid-off workers. The Department of Industrial Relations Cal-WARN page outlines the statute, and an employment lawyer can tell you whether your layoff qualifies.
