Severance Package Negotiation during Layoffs and RIFs: How California Employers Can Minimize Legal Exposure

A layoff feels like a business decision until the severance agreement gets drafted, and then it becomes a legal document that either closes the door on future claims or leaves it wide open. The short answer: severance package negotiation only protects your business if the release is timed correctly, discloses what federal and state law require, and is offered as part of a documented, consistent process across everyone affected.

Get any one of those wrong and the severance check you wrote won't stop the lawsuit that follows. If you're planning a reduction in force, this is where an employment law defense attorney should be involved before the first termination letter goes out, not after.

What a Severance Agreement Is Actually Buying You

A severance agreement typically exchanges additional pay or benefits, beyond what the employee is already legally owed, for a release of claims against the company. That release is the entire point. Without it, you've simply paid someone extra to leave with no reduction in your legal exposure. The release needs to be supported by consideration the employee wasn't already entitled to, since courts won't enforce a waiver where the only thing offered was pay the employee would have received anyway.

For this exchange to hold up, the agreement has to be clear about what's being waived, give the employee a genuine opportunity to review it, and avoid any language that could be read as coercive. A rushed severance offer signed in a termination meeting with no time to think it over is far more likely to unravel later, and it puts the entire agreement at risk over a timing mistake that was easy to avoid.

The OWBPA Rules That Apply the Moment an Employee Is 40 or Older

If any employee affected by the layoff is 40 or older, the federal Older Workers Benefit Protection Act adds strict requirements on top of ordinary contract law. The release must name the Age Discrimination in Employment Act specifically, advise the employee in writing to consult an attorney, and avoid waiving any claims that could arise after the signing date.

•      Individual terminations: at least 21 days to consider the agreement, plus a 7 day period to revoke after signing.

•      Group layoffs or RIFs involving two or more employees 40 or older: at least 45 days to consider, plus the same 7 day revocation window.

•      Group layoffs also require a written disclosure listing job titles and ages of everyone in the decisional unit, both selected and not selected for the layoff.

•      Any material change to the agreement during the review period resets the clock on the consideration period.

Skipping the decisional unit disclosure, shortening the review period, or pressuring an employee to sign early doesn't just risk a bad outcome, it can invalidate the age discrimination waiver entirely. This means the release you paid for never actually took effect, and you're left having paid severance without getting the legal protection that was the entire point of offering it.

Where Cal-WARN Changes the Timeline

Once a layoff crosses into mass layoff territory, a separate set of rules kicks in before severance negotiation even starts. California's WARN Act generally requires employers with 75 or more employees to give 60 days of written notice before a qualifying mass layoff, relocation, or termination, and recent amendments under SB 617 added new disclosure requirements to that notice starting in 2026. Employers cannot condition the mandatory WARN notice or pay on signing a release, though additional severance beyond that baseline can still be tied to one.

Missing the WARN notice window doesn't just create separate liability under Cal-WARN, it also complicates the severance conversation, since employees who feel blindsided by an abrupt layoff are far more likely to push back on signing anything at all. Coordinating notice timing with severance planning is exactly the kind of detail an employer defense attorney reviews before a RIF is finalized, not after employees start asking questions.

Avoiding a Discrimination Claim Hiding Inside the Layoff List

The single biggest legal risk in any RIF isn't the severance agreement itself, it's the selection criteria behind who made the list. A layoff that disproportionately affects employees in a protected age group, or that clusters around employees who recently requested accommodations or filed complaints, can turn a routine reduction in force into a workplace discrimination defense attorney's caseload. Selection criteria should be documented, applied consistently across the entire decisional unit, and reviewed for disparate impact before anyone is notified.

A useful gut check: if you can't explain the business reason each specific person was selected, independent of their age, protected characteristics, or recent complaints, in a sentence or two, the criteria probably needs another look before the list goes final. That exercise takes an afternoon of planning. Reconstructing the same justification after a demand letter arrives takes a lot longer and looks far less credible.

Frequently Asked Questions

Q: How long does an employee, aged 40 or older, have to review a severance agreement in California?

A: Employees 40 or older must be given at least 21 days to consider an individual severance agreement, or 45 days if it's part of a group layoff, plus a 7 day period to revoke after signing. Employers who shorten these windows risk invalidating the age discrimination release entirely.

Q: What is a decisional unit disclosure?

A: It's a written disclosure required under the OWBPA for group layoffs affecting employees 40 or older, listing the job titles and ages of everyone considered for the layoff, both selected and not selected. Missing or incomplete disclosures can void the age discrimination waiver in the severance agreement.

Q: Can an employer require an employee to sign a release to get their WARN Act notice or pay?

A: No. The 60 day WARN notice, or pay in lieu of it, cannot be conditioned on signing a release of claims. Additional severance beyond what WARN requires can still be tied to a release, which is why most severance agreements offer something above the statutory minimum.

Q: Does the California WARN Act apply to every layoff?

A: No. Cal-WARN 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 risk even if the WARN threshold isn't met.

Q: What makes severance consideration legally valid?

A: The employee has to receive something beyond what they were already entitled to, such as extra pay, extended benefits, or outplacement services. A release offered in exchange for pay the employee would have received regardless generally won't be enforceable.

Q: How can an employer reduce the risk of a discrimination claim during a layoff?

A: Document the business reason for each selection, apply the same criteria consistently across the entire decisional unit, and review the list for any pattern involving age, protected characteristics, or recent complaints before finalizing it. A pattern that shows up only after the list is final is much harder to explain than one caught during review.

Q: When should an employer bring in legal counsel for a layoff?

A: Before the layoff list is finalized, ideally while the selection criteria and severance terms are still being drafted, not after employees have been notified. An employment law defense attorney can catch OWBPA and WARN compliance gaps and selection pattern issues while they're still fixable.
