Severance Negotiations and Release of Claims: What California Employers Must Get Right to Avoid Future Lawsuits

Most employers offer severance for one reason: to close the door on future claims. But a signed agreement only protects you if the release inside it is enforceable. In California, some claims can't be waived at all, others can be waived only if you follow specific steps, and a single overreaching clause can hand a former employee a new claim. Getting severance package negotiation right means knowing where those lines are before you make an offer.

The short answer: a California severance release is enforceable when the employee gets real consideration beyond what they're already owed, signs knowingly and voluntarily, and the agreement doesn't try to waive rights the law protects. Releases that bundle in unpaid wages, un-waivable claims, or prohibited restrictions are the ones that end up in court.

What Makes a Severance Release Enforceable?

Three basics apply to every agreement, whether it covers one employee or an entire department:

•        Fresh consideration. Severance must be something extra. Final wages and accrued vacation are already owed under the Labor Code, so they can't be the payment for a release.

•        Knowing and voluntary consent. Plain language, time to review, and notice that the employee can consult a lawyer all support enforceability.

•        Proper scope. The release should only cover what the law allows, including unknown claims through a Civil Code § 1542 waiver. 

Our earlier guide on severance agreements that actually protect your business covers the required clauses and review periods in detail. This post focuses on what a release can and can't actually accomplish for you.

Which Claims Can't Be Released in California?

This is where many templates go wrong. A standard "release of all claims" often can't legally cover:

•        Undisputed wages. Labor Code § 206.5 prohibits requiring a release of wage claims as a condition of paying wages that are due. Pay everything owed first, separately from severance.

•        Business expense reimbursement. Labor Code § 2804 makes the right to reimbursement under § 2802 nonwaivable.

•        Workers' compensation claims. These generally require approval by the Workers' Compensation Appeals Board to settle.

•        Unemployment benefits. An employee can't waive the right to file for unemployment insurance.

•        The right to file agency charges. Employees keep the right to file with or cooperate with the EEOC, the Civil Rights Department, and similar agencies, even if they waive personal recovery.

•        The state's share of PAGA claims. An individual release doesn't necessarily end representative PAGA exposure. See our overview of PAGA reform in 2026.

Including these in a release makes those clauses unenforceable and Labor Code § 432.5 prohibits requiring an employee to agree to terms the employer knows are prohibited by law, which can create a separate claim.

Clauses That Can Backfire

•        Broad non-disparagement or confidentiality. Since SB 331, Government Code § 12964.5 requires specific carve-out language preserving the employee's right to discuss unlawful workplace conduct.

•        Non-competes. Most are void under Business and Professions Code § 16600, and requiring one can now create liability. Our post on non-compete agreements after AB 1076 explains the risk.

•        No-rehire clauses in agreements settling an employment dispute are generally void under Code of Civil Procedure § 1002.5.

•        Clawback terms tied to "any breach." Overly aggressive repayment provisions can look punitive and make a court less willing to enforce the rest of the agreement.

How to Approach Severance Package Negotiation

Severance package negotiation is a legal risk assessment as much as a financial decision. A practical approach:

•        Assess exposure first. Look at complaints, leave, and protected activity before setting an offer. An employee with a strong potential claim warrants a different conversation than a routine separation.

•        Separate what's owed from what's offered. Deliver final pay on time and never condition it on signing.

•        Expect counteroffers when a lawyer is involved. Decide your ceiling and non-negotiable terms in advance.

•        Keep terms consistent across similar employees. Unequal packages can themselves become evidence of discrimination.

•        Follow group-layoff rules when more than one employee is offered severance. See severance negotiation during layoffs and RIFs.

Consider a Santa Cruz winery ending the employment of a tasting room manager who recently raised concerns about unpaid overtime. Offering severance in exchange for a general release without first paying the disputed wages or resolving the claim as a documented bona fide dispute risks an agreement that doesn't cover the very claim the winery worried about most.

Mutual Releases and Reference Terms

Represented employees often ask for two things in return for signing: a mutual release and a neutral reference. Both can be reasonable, but think them through. A mutual release means your business gives up its own claims too, so confirm first that there's no unreturned property, confidential information, or unpaid advance you may need to pursue. If you agree to a neutral reference, make sure whoever answers reference calls knows the terms. A manager who later offers a negative opinion can breach the agreement and invite a new retaliation claim.

Frequently Asked Questions

1.Is severance pay required in California?

No. California law doesn't require severance unless an employment contract, policy, or consistent practice promises it. Once offered, though, the terms must comply with state and federal law to be enforceable.

2.Can we require an employee to sign a release to get their final paycheck?

No. Final wages, including accrued vacation, must be paid on time regardless of whether the employee signs anything. Conditioning final pay on a release can violate Labor Code § 206.5 and trigger waiting time penalties.

3.What is a Civil Code § 1542 waiver?

Section 1542 says a general release doesn't cover unknown claims unless the person expressly waives that protection. California severance agreements typically quote the statute and include an express waiver so the release covers claims the employee may not yet know about.

4.Can a severance agreement stop an employee from filing with the EEOC or Civil Rights Department?

No. Employees keep the right to file charges or participate in agency investigations. A release can waive their right to personal monetary recovery, but language suggesting they can't file at all is unenforceable.

5.How long should an employee have to review a severance agreement?

California requires notice of the right to consult an attorney and at least five business days for agreements covering FEHA-related claims. Employees 40 and older need at least 21 days for an individual separation, or 45 days in a group program, plus seven days to revoke.

6.What happens if part of a severance agreement is unenforceable?

Courts may sever the invalid clause and enforce the rest, especially with a severability provision. But a release with multiple unlawful terms can be voided entirely or create new claims, which defeats the purpose.

7.Should we negotiate severance if the employee has hired a lawyer?

Often, yes. Representation usually signals a potential claim, and a negotiated release can resolve it for less than litigation. Involve your own employer defense attorney before responding to a demand letter.
