Severance Agreements That Actually Protect Your Business: What California Employers Must Include (and What Voids Them)

A severance agreement is one of the most powerful risk-management tools a California employer has. Done right, it resolves a departing employee's potential claims cleanly, protects confidential information, and lets both sides move on. Done wrong, a single defective clause can void the entire release, leaving your business exposed to the lawsuit you thought you'd settled.

California has some of the most employee-protective laws in the country, and the requirements for a fully enforceable severance agreement are more technical than most employers realize. Here's what every California employer needs to know before the next separation happens.

Why Severance Agreements Matter for Employer Defense

California law does not require employers to offer severance pay. But when an employer does offer it, the agreement typically asks the employee to release all known and unknown claims arising from the employment relationship. That release, if properly drafted and executed, can be an extraordinarily effective defense tool.

A well-constructed severance agreement can eliminate exposure to wrongful termination claims, discrimination and harassment claims under FEHA, wage and hour disputes, and retaliation claims, all in one document. For businesses managing complex or contentious separations, it's often far cheaper to structure a defensible severance package up front than to litigate those same claims for two or three years.

The value of the release is only as good as its enforceability, though. Employers who use template agreements pulled from the internet, or agreements that haven't been reviewed against current California law, frequently discover after a lawsuit is filed that the release they were counting on won't hold. Working with an employer defense attorney to draft and review your separation agreements is one of the most cost-effective investments a California business can make.

What Every California Severance Agreement Must Include

There is no single mandatory template, but a legally sound California severance agreement needs several core elements to be enforceable:

Consideration beyond what is already owed. The employee must receive something of real value in exchange for the release, and that value must be above and beyond wages, accrued vacation, or other amounts the employer is already legally required to pay. Offering only what you owe isn't consideration; it's just a payment. Courts have voided severance agreements where the only thing offered was compensation already due.

A clear and specific release of claims. The agreement should explicitly identify the types of claims being released, including state and federal law claims, and should include a waiver of unknown claims under California Civil Code Section 1542. Without the 1542 waiver, an employee may later argue they didn't release claims they didn't know about at the time of signing. That's a significant gap, especially in cases where potential wage and hour violations or discrimination claims weren't fully formed yet.

No waiver of un-waivable rights. Certain rights cannot be released under California law regardless of what the agreement says. These include the right to file a charge with the EEOC or the California Civil Rights Department, the right to file for unemployment benefits, the right to workers' compensation benefits, and the right to pursue PAGA claims on behalf of other employees. Including language that purports to waive these rights doesn't just make those specific clauses unenforceable: courts have struck down entire agreements where unlawful waivers appeared. This is not a technicality. It's a trap that voids the whole deal.

Non-disparagement with a compliant carve-out. Non-disparagement provisions are common and legitimate, but California's Silenced No More Act (SB 331), effective January 1, 2022, prohibits employers from requiring employees to sign NDAs or non-disparagement clauses that prevent them from disclosing factual information related to claims of harassment, discrimination, or retaliation under FEHA. Any non-disparagement clause that lacks the required statutory disclosure language allowing the employee to discuss workplace unlawful acts is unenforceable and potentially exposes the employer to additional liability.

No non-compete provisions. California Business and Professions Code Section 16600 renders non-compete agreements void with very narrow exceptions. Including a non-compete clause in a severance agreement doesn't just make that clause unenforceable: it can signal to a court that the entire agreement was the product of overreaching, which weakens your position on the release as well. Keep non-competes out of California severance agreements entirely.

Special Requirements for Employees Age 40 and Over

If you're asking an employee who is 40 or older to waive age discrimination claims under the federal Age Discrimination in Employment Act (ADEA), the Older Workers Benefit Protection Act (OWBPA) imposes strict additional requirements. Missing any one of them voids the ADEA waiver entirely.

For an individual termination, the employee must be given at least 21 days to consider the agreement before signing, and at least 7 days after signing to revoke it. The agreement must expressly refer to rights and claims under the ADEA, and the employee must be advised in writing to consult an attorney before signing.

For group layoffs involving two or more employees aged 40 and over who are part of the same decision-making process, the consideration period extends to 45 days. The employer must also provide written disclosure identifying the job titles and ages of all employees in the decisional unit who were offered severance and those who were not. This disclosure requirement catches many employers off guard, particularly in rolling reductions in force where terminations are staggered over several months.

The 7-day revocation period is mandatory and cannot be waived, even if the employee wants to waive it. The agreement isn't effective until that window closes. Building a compliant timeline and disclosure process for group separations is one of the things an experienced employer defense attorney can help you get right before a single agreement is signed.

The Review Period and Voluntary Consent Rules

California Government Code Section 12964.5 sets additional timing requirements for employment-related releases. For agreements involving a release of FEHA claims, employees must be given at least five business days to consider the agreement. That minimum sits alongside, not instead of, the OWBPA's 21-day window for employees 40 and over. When both apply, the longer period governs.

The agreement must also be truly voluntary. Presenting a severance agreement under duress, with threats of adverse consequences if the employee doesn't sign immediately, or obtaining consent through misrepresentation, can render the entire agreement voidable on grounds of procedural unconscionability. Allowing the employee meaningful time, encouraging them to consult counsel, and not pressuring a signature creates the record of voluntary consent that makes the release stick in court.

Unconscionability is a broader risk than most employers appreciate. California courts look at both procedural unconscionability (how the agreement was presented) and substantive unconscionability (whether the terms are unreasonably one-sided). An agreement that strips the employee of most meaningful rights while offering minimal compensation is more vulnerable to challenge than one that offers fair value and balanced terms.

What Voids a California Severance Agreement: Common Employer Mistakes

The following are the most frequent reasons California severance agreements fail to provide the protection employers expected:

•        Attempting to waive PAGA claims. Courts have struck down entire agreements, not just the PAGA waiver clause, when employers include unenforceable PAGA waivers. If wage and hour violations affected multiple employees, PAGA exposure may be the biggest risk on the table, and a botched waiver attempt can make things significantly worse.

•        Using a 1542 waiver without the proper statutory language. California Civil Code Section 1542 requires specific language to effectively release unknown claims. Paraphrasing or approximating it isn't sufficient. The exact language or a clear equivalent must be present and intelligible.

•        Including unlawful NDA or non-disparagement terms. Post-SB 331, any confidentiality clause that could be read to prevent the employee from discussing FEHA-related conduct needs a compliant carve-out. Agreements drafted before 2022 that haven't been updated are particularly at risk.

•        Failing to provide adequate consideration time for employees over 40. Skipping or shortening the 21-day or 45-day OWBPA review period, or omitting the required OWBPA disclosure in a group layoff, voids the ADEA waiver. That means the employee can later bring age discrimination claims despite having signed the release.

•        Offering only amounts already owed. If the 'severance' is really just a final paycheck dressed up as a settlement, courts will find no valid consideration and the release will be unenforceable.

Severance Agreements as Part of a Broader Employer Defense Strategy

A severance agreement isn't just a transaction document. Used strategically, it's a tool that fits into a larger employer defense posture alongside well-drafted employment contracts, compliant employee handbooks, documented performance management, and proactive legal counsel before separations happen.

For employers facing a current or anticipated dispute, severance negotiations require a different kind of attention. An employee who is already represented by counsel, who has filed an administrative charge, or who is clearly building a case requires a settlement structure informed by litigation strategy, not just HR process. The amount offered, the scope of the release, the timing, and the structure of confidentiality provisions all affect how defensible the resolution is if the employee later attempts to challenge it.

Frequently Asked Questions

Q: Does California law require employers to offer severance pay?

No. California law does not require employers to offer severance pay unless it is promised in a written employment contract, union agreement, or binding company policy. Severance is voluntary in most situations, but many employers offer it specifically to obtain a release of claims and reduce litigation risk at the time of separation.

Q: Can a California severance agreement release all employment claims?

It can release most, but not all. A properly drafted severance agreement with a valid California Civil Code Section 1542 waiver can release known and unknown claims arising from the employment relationship, including discrimination, harassment, retaliation, and wrongful termination claims. It cannot lawfully release PAGA claims, the right to file administrative charges with the EEOC or California Civil Rights Department, unemployment benefits, or workers' compensation claims. Attempting to waive these un-waivable rights can void the entire agreement.

Q: What is the Silenced No More Act and how does it affect severance agreements?

California's SB 331, effective January 1, 2022, prohibits employers from using NDA or non-disparagement clauses in severance agreements to prevent employees from disclosing factual information related to workplace harassment, discrimination, or retaliation under FEHA. Any such clause must include a specific disclosure telling the employee they retain the right to discuss these matters. Agreements drafted before 2022 or without this language are at real risk of being invalidated.

Q: What happens if we include a non-compete clause in a California severance agreement?

Non-compete provisions are void in California under Business and Professions Code Section 16600, with very narrow exceptions. Including one in a severance agreement doesn't just make that clause unenforceable: it can signal to a court that the agreement was the product of overreaching and weaken the enforceability of the rest of the release. California employers should remove non-compete language from separation agreements entirely and consult an employer defense attorney if trade secret or client solicitation concerns need to be addressed through other legal means.

Q: How long does an employee have to review a severance agreement in California?

For employees under 40, California Government Code Section 12964.5 requires at least five business days to consider an agreement involving a FEHA release. For employees 40 and over who are being asked to waive ADEA claims, the OWBPA requires at least 21 days for individual separations and 45 days when the separation is part of a group layoff involving multiple employees age 40 or older. After signing, employees over 40 have a mandatory 7-day revocation period that cannot be waived by either party.

Q: Can a severance agreement be challenged after it's signed?

Yes. An employee can challenge a signed severance agreement on grounds including lack of adequate consideration, failure to meet OWBPA timing or disclosure requirements, inclusion of unlawful waiver provisions, procedural unconscionability (coercive circumstances), or substantive unconscionability (grossly one-sided terms). A successful challenge can void the entire release, not just the problematic clause, leaving the employer facing claims they believed had been settled. Having agreements drafted and reviewed by an experienced employer defense attorney significantly reduces this risk.

Q: When should an employer involve legal counsel in the severance process?

Before the agreement is drafted, not after the employee has already signed something problematic. An employer defense attorney should review any severance template before it goes into regular use, and should be involved directly in any separation involving a recent internal complaint, an employee with pending or anticipated legal claims, a group layoff, or any employee over 40. The cost of proactive legal review is a fraction of what it costs to litigate a failed release.
