CA WARN Notices: Triggers, SB 617 Content, and Penalties

California WARN notice requirements obligate covered employers to give 60 days’ advance written notice before a mass layoff, relocation, or shutdown that affects 50 or more workers, and to deliver that notice to the affected employees, the Employment Development Department, the local workforce development board, and the chief elected official of each city and county where the action occurs.¹ The rules sit in Labor Code Sections 1400 through 1413 (Cal/WARN), and they apply at lower thresholds and with fewer escape hatches than the federal WARN Act. Skipping or shortening notice triggers back pay, lost benefits, and a daily civil penalty. Starting January 1, 2026, SB 617 also expands what the notice itself has to say.²

Which Employers Are Covered

Cal/WARN applies to any industrial or commercial facility that employs, or has employed within the preceding 12 months, 75 or more people.¹ The statute counts “persons,” without distinguishing full-time from part-time. Federal WARN, by contrast, excludes part-time workers (those averaging fewer than 20 hours per week) from its 100-employee count.³ A California employer with 80 workers, 30 of them part-time, falls under Cal/WARN even if it would miss the federal threshold.

The 12-month look-back closes a shrinkage loophole. If headcount hit 75 at any point during the prior year, the facility is covered, even if the number has since dropped. Track total headcount consistently; the obligation does not disappear because recent payroll came in lower.

What Triggers a Notice

Three types of actions require 60 days’ advance written notice at a covered facility.

Mass layoff. Separating 50 or more employees at the facility within any 30-day period. The 30-day window runs both forward and backward from each separation, so staggering layoffs will not avoid the trigger if the total reaches 50.¹
Relocation. Moving all or substantially all operations to a new site 100 or more miles away.¹
Termination. Shutting down or substantially shutting down all commercial or industrial operations at the facility.¹

Furloughs and Short Temporary Layoffs Count

This is where Cal/WARN catches employers off guard. Federal WARN generally does not treat a layoff as an employment loss unless it runs longer than six months. California’s statute defines a layoff more simply as a separation from a position for lack of funds or work, with no six-month safe harbor. A California appellate court has held that furloughs qualify as layoffs under Cal/WARN regardless of how short the planned duration is. If you furlough 50 or more people at a covered facility, you likely need the full 60 days’ notice even if you plan to recall them in a few weeks.

What the Notice Must Include

The EDD specifies the content of every Cal/WARN notice. The baseline requirements are:

The name and address of the employment site where the layoff, closure, or relocation will occur
A company contact’s name, phone number, and email
Whether the action is permanent or temporary
The expected date of the first separation
The job titles of all affected positions²

New Content Required by SB 617 Starting January 1, 2026

From January 1, 2026, every Cal/WARN notice must also state whether the employer plans to coordinate Rapid Response services through the local workforce development board, through another organization, or not at all. If the employer elects to coordinate services, it must arrange them within 30 days of the notice date.²

Regardless of the coordination choice, the notice must also include:

A working email and phone number for the applicable local workforce development board
A prescribed description of Rapid Response activities, directing workers to their nearest America’s Job Center of California for resume help, interview practice, job searches, and training programs
A description of CalFresh (California’s food assistance program), including the CalFresh benefits helpline number and a link to the CalFresh website²

The EDD has posted the specific language employers must use for the Rapid Response and CalFresh descriptions. Update your templates before filing any 2026 notice to avoid deficiencies.

Who Gets the Notice and How to Deliver It

Written notice must go to all of the following, at least 60 days before the first separation:

Each affected employee, or the union representative where workers are represented
The Employment Development Department
The local workforce development board
The chief elected official of each city and county government where the action occurs¹

For employees, the EDD accepts three delivery methods: first-class mail, personal delivery (an optional signed receipt helps document it), or inclusion in the pay envelope. Notices to the EDD go to its designated WARN notice email address; there is no online portal.² Keep proof of delivery for every recipient.

When Shorter Notice Is Allowed

Cal/WARN recognizes a limited set of situations in which notice is reduced or excused. These are read narrowly, and the employer carries the burden of proving one applies.

Physical calamity or act of war. No notice is required when the layoff, closure, or relocation is caused by a physical calamity or an act of war.²
Actively seeking capital or business. An employer planning a relocation or termination (not a mass layoff) can apply to the Department of Industrial Relations for an exemption if it was actively seeking capital or business and giving notice would have prevented obtaining the financing. The employer must submit documentation, and the DIR decides.²
Project-based and seasonal work. The notice rules do not apply to workers in the motion picture, construction, drilling, logging, or mining industries hired with the understanding that the job was tied to a specific project. Seasonal employees hired with the same understanding are also exempt.²

Even when an exception applies, give as much notice as possible and document why 60 days was not feasible. The EDD still expects a WARN notice to be filed with an explanation for the shortened timeline.²

Penalties for Missing or Shortening the Notice

Under Labor Code Section 1402, an employer that fails to give proper notice owes each affected employee back pay at the higher of two rates: the employee’s average regular compensation over the last three years, or the final rate of pay. The employer also owes the value of lost benefits, including health insurance premiums and any medical expenses a benefit plan would have covered.¹

Liability runs for the length of the violation, capped at 60 days or half the total days the employee worked for the employer, whichever is smaller.¹ A worker who had been on payroll only 40 days, for example, would be capped at 20 days of back pay.

If the employer also failed to notify the local government, a separate civil penalty of up to $500 per day of violation applies. The employer can avoid that penalty entirely by paying all affected employees the amounts owed under Section 1402 within three weeks of ordering the layoff, relocation, or closure.¹

Three categories of payment reduce what the employer owes under Section 1402: wages paid during the violation period (excluding vacation that accrued before the violation), voluntary and unconditional payments not required by any legal obligation, and payments made to third parties on the employee’s behalf during the violation period, such as health premiums or pension contributions.¹ Severance can count as an offset, but only if it was truly voluntary; severance already owed under a contract or policy does not reduce WARN liability.

Why Federal Compliance Is Not Enough

When both laws apply, California employers must satisfy both Cal/WARN and the federal WARN Act, and the stricter rule controls. The gaps that cause the most trouble:

Employer size. Federal WARN covers employers with 100 or more employees and excludes part-timers; Cal/WARN covers facilities with 75 or more people and counts everyone on payroll.³
Mass layoff numbers. Federal WARN requires 500 affected workers, or 50 to 499 if they are at least 33 percent of the workforce. Cal/WARN triggers at 50 with no percentage requirement.¹
Short layoffs. Federal WARN generally ignores layoffs under six months; Cal/WARN does not, and courts have treated short furloughs as covered layoffs.
Exceptions. Federal WARN recognizes unforeseeable business circumstances and natural disaster exceptions that can shorten notice. Cal/WARN’s exceptions are narrower, and the actively-seeking-capital exemption is not available for mass layoffs.

Plan around the California thresholds. They are the ones most likely to apply first, and they leave less room to maneuver.
