Layoff Severance Agreements in California: How Employers Reduce Legal Risk

A layoff looks like a business decision until someone drafts the severance agreement. At that point it becomes a legal document that either shuts the door on future claims or leaves it wide open.

A severance package only protects your company if three things are true. The release has to be timed correctly. It has to include the disclosures federal and state law require. And it has to be offered through a documented, consistent process that treats similarly situated employees the same way. If any one of these fails, the severance check you wrote may not stop the lawsuit that follows.

That is why an experienced employer defense attorney should be involved before the first termination letter goes out, not after employees start asking questions.

What a Severance Agreement Actually Buys You

A severance agreement is an exchange. The company provides pay or benefits beyond what the employee is already owed, and the employee releases legal claims against the company. The release is the whole point. Without it, you have simply paid someone extra to leave.

Courts will not enforce a waiver unless the employee received something new in return. Final wages, accrued vacation, and other amounts the law already requires do not count as consideration. Extra pay, extended benefits, or outplacement services can.

The agreement also has to be clear about what is being waived, give the employee a real chance to review it, and avoid language that reads as coercive. An offer handed over in a termination meeting with a demand to sign on the spot is far more likely to unravel later. That is a timing mistake, and it is easy to avoid.

OWBPA Requirements for Employees Age 40 and Older

When any affected employee is 40 or older, the federal Older Workers Benefit Protection Act (OWBPA) layers strict requirements on top of ordinary contract rules. The release must specifically reference the Age Discrimination in Employment Act, advise the employee in writing to consult an attorney, and exclude claims that arise after the signing date.

The timing rules depend on the type of separation:

• Individual termination: At least 21 days to consider the agreement, plus 7 days to revoke after signing.

• Group layoff or RIF (two or more employees, at least one aged 40 or older): At least 45 days to consider, plus the same 7-day revocation period.

• Group disclosure: A written list of the job titles and ages of everyone in the decisional unit, both those selected and those not selected.

• Material changes: A significant change to the agreement during the review period can restart the consideration clock.

Cutting the review period short, leaving out the decisional unit disclosure, or pressuring someone to sign early can invalidate the age discrimination waiver. You will have paid for a release that never took effect. Anyone who has handled these disputes as an employer defense attorney will tell you the same thing: the paperwork mistakes are the ones that cost the most, because they are preventable.

How Cal-WARN Changes the Timeline

Once a layoff reaches mass-layoff scale, a separate set of rules applies before severance negotiations even begin. California's WARN Act generally covers employers with 75 or more employees and requires 60 days of written notice before a qualifying mass layoff, relocation, or termination. Recent amendments under SB 617 added new disclosure requirements to that notice beginning in 2026.

One point trips up many employers. You cannot condition the required WARN notice or pay in lieu of notice on the employee signing a release. Severance offered above that baseline can still be tied to a release, which is why well-built packages include something beyond the statutory minimum.

Missing the notice window creates its own liability, and it also makes severance harder to negotiate. Employees who feel blindsided are much less willing to sign anything. Coordinating WARN timing with severance planning is exactly what a California employer defense attorney reviews before a RIF is finalized.

The Discrimination Claim Hiding in Your Layoff List

The biggest legal risk in a reduction in force is usually not the severance agreement. It is the selection criteria behind who ended up on the list.

A layoff that falls disproportionately on employees in a protected age group can draw a discrimination claim. So can one that clusters around employees who recently requested accommodations, took protected leave, or raised complaints. Any of these patterns can turn a routine RIF into a full-blown defense matter.

To reduce that risk, employers should:

1. Document the business reason for each selection.

2. Apply the same criteria consistently across the entire decisional unit.

3. Review the final list for disparate impact before anyone is notified.

Here is a simple gut check. If you cannot explain in a sentence or two why each person was selected, independent of age, protected status, or recent complaints, revisit the criteria before the list goes final. That exercise takes an afternoon. Reconstructing the same justification after a demand letter arrives takes far longer and looks much less credible.

Why Early Legal Review Matters

Severance negotiation works best as the last step in a well-planned layoff, not the first. By the time severance terms are on the table, the decisions that create most of your exposure have already been made: who was selected, how much notice was given, and how the process was documented.

Bringing in counsel while those decisions are still open lets you fix problems before they become claims. An employer defense attorney can spot OWBPA gaps, WARN timing issues, and troubling selection patterns while they are still easy to correct.

Frequently Asked Questions

How long does an employee age 40 or older have to review a severance agreement?
At least 21 days for an individual separation, or 45 days when the agreement is part of a group layoff. Either way, the employee also gets 7 days to revoke after signing. Shortening these windows risks invalidating the age discrimination release.

What is a decisional unit disclosure?
It is a written OWBPA disclosure for group layoffs involving employees aged 40 or older. It lists the job titles and ages of everyone considered for the layoff, both selected and not selected. A missing or incomplete disclosure can void the age discrimination waiver.

Can an employer require a release in exchange for WARN notice or pay?
No. The 60-day notice, or pay in lieu of it, cannot be conditioned on signing a release. Additional severance beyond the statutory minimum can be.

Does Cal-WARN apply to every layoff?
No. It generally applies to employers with 75 or more employees and is triggered by qualifying mass layoffs, relocations, or terminations at a covered establishment. Smaller layoffs may still carry other legal risks even when the WARN threshold is not met.

What makes severance consideration legally valid?
The employee must receive something beyond what they were already entitled to, such as additional pay, extended benefits, or outplacement services. A release given in exchange for pay the employee would have received anyway generally will not be enforced.

When should an employer call an employer defense attorney about a layoff?
Before the layoff list is finalized, while selection criteria and severance terms are still being drafted. Waiting until employees have been notified leaves far fewer options for fixing problems.
