California WARN Act: Coverage, Notice, and Penalties
Who Cal-WARN covers at 75 employees, what triggers 60-day notice, the four required recipients, the new notice content rules, and the penalties.
California WARN Act
Who is covered at 75 employees, what triggers a 60-day notice, who has to receive it, what the notice must now contain, and what getting it wrong costs
Most of what ranks for this topic is written for the person who was laid off. That content is genuinely useful, and it answers a different question than the one an employer has. If you are running a California business and a reduction is on the table, you need to know three things quickly: whether the law applies to you, exactly what you have to send and to whom, and what happens if you get it wrong.
The short version of the first one catches a lot of people out. California's threshold is 75 employees, not the federal 100, and it counts part-time staff. That means a band of mid-sized California employers are covered by state law while sitting comfortably below the federal line, and they generally find this out at the worst possible moment.
This guide covers coverage, triggers, the four notice recipients, what the notice must contain including the requirements added for notices issued from the start of 2026, the exceptions that are narrower than most people assume, and the penalty arithmetic. I build the employee record and offboarding infrastructure this runs on at FirstHR. This is general information rather than legal advice, and a layoff is one of the clearest cases for having an employment attorney review the plan before you act.
What Cal-WARN Is
The California WARN Act is a state notice law requiring covered employers to warn employees and government before a large workforce reduction. It does not prohibit the reduction. It requires you to give people time.
The purpose of the law is to give displaced workers and the local workforce system a runway. That framing is worth holding onto, because it explains most of the design: why four recipients rather than one, why the notice must describe the services available, and why the penalty is measured in days of pay rather than as a flat fine.
One clarification that resolves a common confusion: Cal-WARN does not limit your right to conduct a reduction. California is an at-will employment state and the law here is procedural, not substantive. You can lay people off for business reasons. What the statute controls is how much warning you give and who you give it to, and the penalty for skipping that step is measured in the pay you would have owed during the notice period rather than in a reversal of the decision.
It also explains something practical. The state is not looking to catch employers out. The EDD publishes a step-by-step filing process and rapid response teams exist to help. The failures that end in litigation are almost always failures to notice the obligation existed, not failures to comply once it was understood.
Who Is Covered
Two numbers do all the work here, and confusing them is the most common analytical error on this topic.
The employer threshold is 75. Cal-WARN applies to a covered establishment, meaning any industrial or commercial facility that employs, or has employed within the preceding 12 months, 75 or more people. Both full-time and part-time employees count toward that number.
The event threshold is 50. A mass layoff means 50 or more employees losing their positions at that establishment within a 30-day period.
Note also that coverage attaches to the establishment rather than to the company as a whole. A company with several California sites analyzes each one, and the analysis of one location does not settle the answer for another.
What Triggers the Notice Requirement
Three distinct events trigger Cal-WARN, and only one of them is what most people picture when they think of the law.
The relocation trigger deserves particular attention because it has no federal counterpart and because it does not feel like a layoff to the employer doing it. A California company consolidating operations to a facility 120 miles away is moving, not cutting, and may still owe notice.
Temporary actions are the other blind spot. California appellate authority has held that a temporary layoff or furlough can trigger the notice requirement, so an employer planning a furlough of 50 or more people at a covered establishment cannot assume that the temporary framing removes the obligation.
Cal-WARN vs the Federal WARN Act
Both laws can apply to the same event, and they operate independently. Satisfying one does not satisfy the other, and liability under each is calculated separately.
| Federal WARN | Cal-WARN | |
|---|---|---|
| Employer threshold | 100 employees | 75 at a covered establishment |
| Part-time employees counted | Generally excluded | Counted |
| Mass layoff trigger | 50 plus a 33 percent workforce test, or 500 regardless | 50, with no percentage test |
| Closure threshold | 50 or more affected | Essentially any number |
| Relocation trigger | None | 100 miles or more |
| Unforeseeable business circumstances | Available | Not adopted |
| Faltering company exception | Closures only | Termination or relocation, not mass layoffs |
| Notice period | 60 days | 60 days |
The pattern is consistent: California is broader on coverage and narrower on excuses. In practice this means that for a California establishment, the analysis that matters is the state one. If you clear Cal-WARN you have almost certainly cleared federal WARN, and the reverse is not true.
The 75 to 99 Employee Band
This is the section that does not exist anywhere else on this topic, and it describes a specific and awkward position.
If your California establishment has between 75 and 99 employees, you are covered by Cal-WARN and not by federal WARN. Every generic article about the WARN Act, every summary that starts at 100 employees, and quite possibly your own recollection of the law all point the wrong way for you.
Concretely: a 90-person California business laying off 50 people owes a full Cal-WARN notice to four recipients, 60 days in advance, with all the required content, and faces the full penalty structure if it does not. The federal law is silent on that event entirely.
The exposure is not proportionally smaller either. The penalty is calculated per affected employee, and the event definition guarantees at least 50 of them. A 90-person business faces essentially the same arithmetic as a 900-person business running the same 50-person layoff, against a much smaller balance sheet. In practice this is the one compliance obligation where a mid-sized California employer's downside is close to an existential number rather than a line item.
Two things follow for a business in this band. The first is that headcount monitoring is a compliance function, not just a planning one. Crossing 75, including with part-time hires, changes your legal obligations in a way that nothing will announce to you. The second is that the analysis has to happen at the point a reduction is first discussed, not when it is scheduled, because 60 days is a long time when the reason for the reduction is that money is running out.
Who Has to Receive the Notice
Four recipients. This is the most mechanical part of Cal-WARN compliance and one of the most commonly botched.
The chief elected official is the recipient that gets missed. It is not intuitive that a city mayor needs a copy of your layoff notice, and there is no single directory of who to send it to. The EDD FAQ directs employers to their Local Area administrator to identify the correct official, which is worth doing early rather than on day 58.
What the Notice Has to Say
Cal-WARN incorporates the content elements required under the federal WARN regulations and then adds California-specific requirements on top.
The federal baseline includes the name and address of the employment site, whether the action is expected to be permanent or temporary and whether the entire site is closing, the expected date of the first separation and the anticipated schedule, the job titles of affected positions and the number of employees in each, whether bumping rights exist, and the name and contact details of a company official who can provide further information.
What the notice does not have to contain is worth noting too. There is no requirement to explain the business reasons for the reduction, and no requirement to offer severance. Cal-WARN is a notice statute, not a severance statute, and California has no general law requiring severance pay. If you do offer it, that is a separate document with its own considerations, and pay in lieu of notice does not substitute for the notice itself.
Beyond content, one practical point about tone. The notice is a legal document and it is also the thing a person reads when they learn they are losing their job. Those two purposes are not in conflict, but a notice drafted purely as the former reads badly. Sending it alongside a clear explanation of continuation coverage and final pay timing is both kinder and fewer questions for you.
California has its own strict rules on that final payment, and they run on a separate clock from the WARN notice. Accrued vacation is treated as earned wages in California and must be paid out at separation, and final wages are generally due on the last day of employment for a layoff. An employer that gets the 60-day notice right and the final paycheck wrong has traded one wage claim for another, so plan both together rather than sequentially.
What the Recent Amendment Added
Senate Bill 617 amended Labor Code section 1401 and applies to notices issued on or after January 1, 2026. It changed nothing about who is covered or what triggers notice. It expanded what the notice must contain.
The EDD summarized the change in a workforce services information notice, which is the shortest authoritative statement of the new requirements and is worth reading directly before you finalize a template.
One further signal worth tracking rather than acting on: an executive order signed in May 2026 directs the state labor agency to recommend revisions to Cal-WARN within 180 days. That is a recommendation process, not a change in law, but it means this is an area to recheck rather than to consider settled.
Timing and Delivery
Sixty days means 60 calendar days before the action takes effect, and the notice must be received by that point rather than merely sent.
Acceptable delivery to employees is a method that ensures receipt: first-class mail, personal delivery, or inclusion in the pay envelope. The EDD filing goes by email with the employer name in the subject line and the notice attached.
If you genuinely cannot give the full 60 days, the guidance from the state is still to file the notice and include an explanation of why the full period was not possible. A late notice with a reason is a better position than no notice, both practically and legally.
The Exceptions Are Narrower Than You Think
This is where employers relying on general WARN knowledge get into trouble, because the federal exceptions are broader and better known.
California recognizes a physical calamity exception and an act of war exception. The faltering company exception exists but applies only to a termination or a relocation, not to a mass layoff. And California has not adopted the federal unforeseeable business circumstances exception at all.
That last point is the important one. A sudden and unexpected business reversal, the classic scenario that shortens notice under federal WARN, does not have a corresponding California exception. An employer whose funding falls through in a week is in a genuinely difficult position under Cal-WARN, and it is the position most likely to produce a claim.
An employer actively seeking capital or business that would allow it to avoid or postpone the action can request a determination from the Director under Labor Code section 1402.5. That is a process to start early, not a defense to assert afterward.
Cal-WARN also does not reach work that everyone understood to be of limited duration: a defined project, or seasonal work where employees were hired on that basis. If you rely on this, the understanding needs to have been documented at hire rather than characterized that way later.
What Non-Compliance Costs
The penalty structure is designed so that the cost scales with the number of people affected, which for a covered event is at least 50.
The back pay calculation is set out at Labor Code section 1402: the higher of the employee's average regular rate over the last three years of employment or their final rate, for up to a maximum of 60 days or one-half the number of days they were employed, whichever period is smaller. Lost benefits, including medical expenses that would have been covered, are added on top.
Two features make this worse than the headline number suggests. Prevailing employees can recover attorney fees, which is what makes these cases economically attractive to bring. And the three-year statute of limitations combined with a per-employee calculation makes class treatment the norm rather than the exception.
The one piece of relief in the structure: the civil penalty specifically can be avoided if the employer satisfies its liability to each affected employee within three weeks of the closing. That is a narrow window and a reason to get advice immediately if you discover a notice failure rather than waiting to see whether anyone notices.
If You Employ People in Other States Too
Multi-state employers face two problems at once: satisfying both federal and California law for the California site, and dealing with whatever other states require.
For the California site, run the Cal-WARN analysis and treat federal WARN as a floor you will clear along the way. The state thresholds are lower and the exceptions narrower, so a plan built to satisfy California will generally satisfy the federal law for the same event, while the reverse fails.
The planning side matters as much as the filing side. A reduction in force that is scoped before the notice analysis frequently has to be rescoped after it, because the 50-person threshold and the 30-day window turn out to sit awkwardly against the plan. Running the Cal-WARN analysis while the reduction is still being designed, rather than after it is decided, is the difference between shaping the plan and discovering a constraint.
For other states, check individually. Several states have their own mini-WARN statutes with their own thresholds, notice periods, and recipient lists, and a few require longer than 60 days. There is no shortcut here: the obligation follows the establishment, so each site gets its own analysis.
One coordination point that matters practically: aggregation. Federal WARN aggregates employment losses at a single site over a 90-day period in some circumstances, and California counts staggered reductions inside a 30-day window as one event. If you are planning phased reductions across a year, the phasing is exactly the thing a plaintiff will examine, so document the independent business reason for each phase at the time you decide it rather than reconstructing it later. Keeping that documentation alongside your payroll records for at least the three-year limitations period is the minimum.
The Compliance Workflow
What to actually do, in order, from the moment a reduction becomes a real possibility.
Mistakes That Create Liability
Everything after the notice is standard offboarding, but the volume changes the nature of it. Fifty simultaneous separations means fifty final paychecks calculated correctly on the same day, fifty sets of access to revoke, fifty benefits terminations, and fifty continuation coverage notices. Whatever process works for one departure at a time tends to fail at that volume, and the failures are the kind that generate individual claims on top of the WARN exposure. Employee record retention obligations also continue after separation and are not suspended because the person no longer works there.
Almost every Cal-WARN failure is one of a small number of predictable errors, and none of them is expensive to avoid.
The through-line is that this is a knowledge failure rather than an effort failure. The compliance act itself is a letter, correctly drafted, sent to four recipients, 60 days early. What produces nine-figure aggregate exposure across California employers every year is not employers refusing to send that letter. It is employers who did not know the letter was required until an attorney told them, which is why the headcount check belongs in your compliance routine rather than in your layoff planning.
Frequently Asked Questions
What is the California WARN Act?
The California WARN Act, usually shortened to Cal-WARN and codified at Labor Code sections 1400 through 1408, requires covered employers to give at least 60 calendar days of advance written notice before a mass layoff, a termination of operations, or a relocation of 100 miles or more. Notice must go to affected employees, the Employment Development Department, the Local Workforce Development Area, and the chief elected official of each affected city and county. It supplements the federal WARN Act rather than replacing it, and it is broader than the federal law in every material respect.
How many employees triggers the California WARN Act?
Two separate numbers matter and they are frequently confused. The employer threshold is 75: Cal-WARN applies to a covered establishment that employs, or has employed within the preceding 12 months, 75 or more people, counting both full-time and part-time employees. The event threshold for a mass layoff is 50: a layoff of 50 or more employees at that establishment within any 30-day period. So a 90-person California business laying off 50 people is covered, even though the same business would fall below the federal WARN threshold of 100 employees.
What is the difference between Cal-WARN and the federal WARN Act?
Cal-WARN is broader on every dimension. The employer threshold is 75 rather than 100, and part-time employees count toward it. The mass layoff trigger is 50 employees with no percentage-of-workforce test, whereas federal WARN includes a 33 percent test. A termination of operations in California can trigger notice regardless of how many people are affected. California uniquely covers relocations of 100 miles or more. And California has not adopted the federal unforeseeable business circumstances exception. Both laws can apply at once, producing parallel and independent liability.
Do part-time employees count toward the 75-employee threshold?
Yes. This is one of the most consequential differences from federal WARN, which generally excludes part-time employees from its 100-person count. Cal-WARN counts both full-time and part-time employees toward the 75-person covered establishment threshold. Separately, to be counted at all, an employee must have worked at least 6 of the 12 months preceding the date the notice is required. Employers with a large part-time or hourly workforce, such as retail, hospitality, and food service operations, routinely cross the threshold without realizing it.
Who must receive a Cal-WARN notice?
Four recipients, all of them required. First, every affected employee, or their union representative where one exists. Second, the California Employment Development Department, filed by email with the employer name in the subject line. Third, the Local Workforce Development Area for the region, which coordinates rapid response services. Fourth, the chief elected official of each city and county government affected, which is typically the mayor or board chair. Missing the fourth recipient is the most common service failure, and your Local Area can identify the correct official if you do not know.
What must a California WARN notice contain?
The notice must carry the elements required under the federal WARN regulations, including the employer name and address, whether the action is permanent or temporary, the expected date of the first separation, the job titles affected, and a company contact. California adds its own requirements. Notices issued from the start of 2026 must also state whether the employer will coordinate services through the Local Workforce Development Board, another entity, or not at all, and must include the board's contact details and prescribed service description, a description of CalFresh with its helpline and website, and a functioning employer email and phone number.
What are the penalties for violating Cal-WARN?
An employer that fails to give proper notice is liable to each affected employee for back pay and the value of lost benefits, including any medical expenses incurred that would have been covered. Back pay is calculated at the higher of the employee's average regular rate over the last three years of employment or their final rate, for up to a maximum of 60 days or one-half the days they were employed, whichever is smaller. On top of that sits a civil penalty of up to $500 for each day of violation, payable to the affected local government, which can be avoided if the employer satisfies its liability to each affected employee within three weeks. Prevailing employees can recover attorney fees.
Does Cal-WARN apply to temporary layoffs and furloughs?
It can. California appellate authority has held that a temporary layoff or furlough can trigger the Cal-WARN notice requirement, which is a meaningful departure from how many employers instinctively read the law. The practical implication is that an employer planning a furlough of 50 or more people at a covered establishment cannot assume the temporary nature of the action removes the obligation. This is an area where the answer depends heavily on specific facts, so it is worth confirming with employment counsel before proceeding rather than after.
Are there exceptions to the 60-day notice requirement?
Fewer than under federal law. California recognizes a physical calamity exception and an act of war exception. The faltering company exception applies only to a termination or relocation, not to a mass layoff. California has not adopted the federal unforeseeable business circumstances exception, so a sudden business reversal that would excuse short notice federally may not excuse it in California. Cal-WARN also does not apply where employees were hired with the understanding the work was of limited duration, such as a defined project or seasonal work. An employer actively seeking capital or business can request a determination from the Director under Labor Code section 1402.5.
What is the statute of limitations for a Cal-WARN claim?
Three years. Because the damages are calculated per employee and a covered event by definition affects at least 50 people, and often many more, these claims are commonly brought as class actions. That structure is what makes the exposure serious relative to the cost of compliance: the underlying obligation is a letter sent on time to four recipients, while the failure produces a multi-plaintiff wage claim with attorney fees attached. Keep the notices, the service records, and the headcount analysis that supported your coverage determination for at least that long.
