California WARN Notices: Triggers, Exceptions, and Penalties

The California WARN Act requires employers with 75 or more workers to give 60 days’ written notice before a mass layoff of 50 or more employees, a facility closure, or a relocation of operations 100 or more miles away. The notice has to go to each affected employee individually, the Employment Development Department, the local workforce development board, and the chief elected official of the city and county where the action occurs. Skipping it exposes the employer to back pay, benefit costs, and a civil penalty of up to $500 per day of violation.¹

Which Employers Are Covered

The statute applies to any “covered establishment,” meaning an industrial or commercial facility that employs or has employed 75 or more people within the preceding 12 months.¹ Both full-time and part-time workers count toward the 75.² That is a meaningful difference from federal WARN, which excludes part-time employees.

To be counted, a worker must have been employed for at least 6 of the 12 months before notice would be required.² Someone hired three months ago for a short-term project does not push the headcount over the line. Because the lookback runs a full year, employers should be tracking staffing over time rather than checking a single pay period on the day they announce.

What Triggers a Notice

Three workforce actions trigger the 60-day obligation:

Mass layoff. A layoff of 50 or more employees at a covered establishment during any 30-day period. Unlike federal law, California does not require the layoff to last more than six months, so even a short or temporary layoff can trigger notice.¹
Relocation. Moving all or substantially all of a facility’s operations to a new location 100 or more miles away.¹
Termination. The cessation or substantial cessation of industrial or commercial operations at a covered establishment. In the statute’s terminology this means a facility closure, not the firing of an individual.¹

The 50-employee threshold for a mass layoff is absolute. It applies the same way whether the facility has 80 workers or 8,000.

What the Notice Must Include

California requires everything the federal WARN Act requires, plus several state-specific items.³ The federal content includes the name and address of the affected site, the job titles of the positions being eliminated, the number of employees in each classification, the expected date of the first separation, and whether the action is permanent or temporary.

On top of that, the California notice must state whether the employer plans to coordinate rapid response services through the local workforce development board or a different entity, and it must include a working email address and phone number for both the employer and the local workforce development board. It must also describe the CalFresh food assistance program and provide the CalFresh helpline number and website.³ If the employer coordinates rapid response services, those services must be arranged within 30 days of the notice date.

Who Gets the Notice

The 60-day notice must reach four recipients before the first separation:³

Each affected employee, individually. Notifying a union representative is not enough under California law, even if the workforce is organized.
The Employment Development Department.
The local workforce development board.
The chief elected official of each city and county where the layoff, relocation, or closure occurs.

Acceptable delivery methods for the employee notice include first-class mail, personal delivery, and inclusion in the pay envelope.² A preprinted notice that already appears routinely in pay envelopes will not satisfy the requirement. It has to be a distinct communication.

When Less Than 60 Days Is Allowed

Three situations can excuse or shorten the notice period.

Physical Calamity or Act of War

The 60-day requirement does not apply if the mass layoff, relocation, or closure is caused by a physical calamity or act of war.³ An earthquake destroying a warehouse or a flood shutting down a plant would fit. The event must be the actual cause; an employer cannot invoke it for a shutdown that was already planned.

Faltering Company

An employer that was actively seeking capital or business it reasonably believed would let it avoid or postpone a closure or relocation may give shorter notice, if it reasonably believed that giving the full notice would have driven off the needed financing. To use the exception, the employer must submit documentation and a sworn affidavit to the EDD proving it was genuinely pursuing the investment.⁴ This exception is narrow in one important way: it covers relocations and facility closures, not mass layoffs.

Unforeseeable Business Circumstances

Under the federal WARN Act, employers can give reduced notice when the triggering event was caused by business circumstances not reasonably foreseeable when notice would have been due. Federal regulations describe qualifying events as “sudden, dramatic, and unexpected,” such as a major client abruptly canceling a contract or a strike at a critical supplier.⁵ California courts have looked to this federal framework when evaluating similar claims under the state act, though the California statute itself does not spell the exception out as explicitly.

Project-Based and Seasonal Work

Certain project-based work is outside the act entirely. The law does not apply when a closure or layoff results from a completed project in broadcasting, motion picture production, or certain on-site construction, drilling, logging, and mining occupations. The exemption applies only if the employees were hired with the understanding that the job was tied to that specific project’s duration.¹

Seasonal employment is also outside the act, provided the workers were hired with the understanding that the position was seasonal and temporary.² In both categories the key is documented mutual understanding at the time of hire. An employer who tries to recharacterize permanent employees as “project” workers right before a layoff is unlikely to hold up under this exemption.

What Noncompliance Costs

An employer that fails to give the required notice faces liability on several fronts. Affected employees can recover back pay calculated at their final rate of compensation or their three-year average rate, whichever is higher, plus the cost of medical expenses that would have been covered under the benefit plan during the violation period.²

The liability period runs up to 60 days, or one-half the number of days the employee was employed, whichever is shorter.² An employee who worked 40 days before the violation caps out at 20 days of back pay, not 60. On top of individual claims, the employer faces a civil penalty of up to $500 for each day of the violation.

Any affected person, employee representative, or local government can bring a civil action. Courts may award reasonable attorney’s fees to a prevailing plaintiff.⁶ Only a winning plaintiff gets fees under the California statute, not a winning defendant. In a large layoff the combined exposure — back pay for dozens or hundreds of workers, benefit costs, daily penalties, and plaintiffs’ fees — adds up quickly.

Using Severance to Offset Damages

An employer that has already fallen short on notice sometimes tries to limit exposure with severance. Under federal WARN guidance, voluntary and unconditional severance payments can offset the back pay obligation, but only if those payments were not already required by a contract, collective bargaining agreement, or company policy.⁷ Severance already owed under an existing agreement cannot be double-counted.

An employer can also condition severance on the employee waiving a WARN claim. For the waiver to hold up, the employee must agree voluntarily and knowingly, have a real opportunity to consult an attorney, and receive something of value beyond what they were already owed.⁷ A release buried in fine print and handed over on the last day, with no time to review, is the kind of waiver courts look at hardest.

Sales and Acquisitions

When a covered business is sold, WARN responsibility follows a timing rule. The seller is responsible for any layoff or closure that occurs up to and including the sale date; the buyer is responsible for anything after that.⁸ Neither side can shift the obligation onto the other. The date of the employment loss controls.

Employees of the seller automatically become employees of the buyer for WARN purposes at closing. If workers keep their jobs through the transition, the change in ownership by itself is not an employment loss.⁸ The risk shows up when a buyer acquires a facility and then lays off workers shortly after closing. If fewer than 60 days pass between the acquisition and the layoff, the buyer may owe WARN damages unless an exception applies.

Where California Is Stricter Than Federal WARN

Both laws can apply to the same layoff, and a California employer has to meet whichever requirement is tougher on each point. The state act is stricter in several places:

Coverage threshold. California covers facilities with 75 or more workers and counts part-time employees. Federal law requires 100 or more and excludes part-timers from the count.¹
No minimum layoff duration. Federal law requires a layoff to last more than six months to trigger notice. California has no such requirement.
Direct employee notice. Federal law lets an employer satisfy notice through a union representative. California requires notice to each affected employee individually.³
Back pay calculation. California uses the employee’s final rate or three-year average rate, whichever is higher.²
Attorney fees favor employees. California awards fees only to a prevailing plaintiff. Federal law allows fees to any prevailing party, which can include a winning employer.⁶
No strike or lockout exception. The federal WARN Act exempts closures and layoffs resulting from a strike or a lockout not intended to evade the law. California’s statute has no parallel exemption.²

In practice, a California employer planning a large workforce action should build the plan around the state act first and then check whether federal WARN adds anything on top.
