A California employment separation agreement is a contract that trades severance pay for your release of legal claims against the employer, and California law puts real limits on what the employer can ask you to give up. Before you sign, you need to know what rights are off the table no matter what the agreement says, what minimum time you’re entitled to for review, and which common clauses — non-competes, broad confidentiality terms, wage releases — are unenforceable here even when they appear in the draft.
What the Employer Is Actually Buying
No California or federal law requires an employer to offer severance. Severance is a private deal, voluntary on both sides, and employers offer it because they want a signed release of claims that reduces their litigation risk.1U.S. Department of Labor. Severance Pay That framing matters: you are selling something (your right to sue), and the severance is the price.
A standard agreement will set the severance amount (lump sum or salary continuation), spell out the claims being released, address confidentiality and non-disparagement, cover return of company property, note COBRA continuation, and fix the separation date. The separation date drives final-pay deadlines, benefits cutoffs, and the start of any post-employment terms.
For the release to be enforceable, the employer has to give you something beyond what you’re already legally owed. Your final paycheck and accrued vacation are not consideration — those are yours regardless. The severance has to add extra pay, extended benefits, outplacement, or something comparable on top.
Rights You Cannot Sign Away
Several categories of rights are protected by statute and cannot be released in a private agreement, no matter how the clause is drafted.
- Earned wages. California Labor Code Section 206.5 makes it illegal for an employer to require a release of wages that are due or will become due as a condition of being paid. Any such release is void, and demanding one is a misdemeanor. This covers regular pay, accrued vacation, overtime, and commissions.2California Legislative Information. California Code LAB 206.5
- Unemployment insurance. Unemployment Insurance Code Section 1342 declares any waiver of benefits or rights under the code invalid. The employer cannot condition severance on your giving up unemployment claims.3California Legislative Information. California Code UIC 1342
- Workers’ compensation. These rights are protected by statute and can’t be bargained away in a private agreement.
- Federal wage claims. Unpaid overtime or minimum wage claims under the Fair Labor Standards Act generally require Department of Labor or court supervision to settle; a separation agreement alone usually can’t release them.
The underlying principle: a separation agreement can release potential legal claims you might file, but it can’t take away wages you’ve already earned or benefits the law guarantees.
The Section 1542 Waiver for Unknown Claims
California Civil Code Section 1542 provides that a general release does not cover claims you did not know about when you signed.4California Legislative Information. California Code Civil Code 1542 An employer who wants you to waive unknown claims has to specifically reference Section 1542 in the agreement and include language putting you on notice that you’re giving up claims you may not yet be aware of. Skip that step, and the waiver of unknown claims is open to challenge.
This rule exists because wage calculation errors, safety issues, and discriminatory patterns often surface only after an employee leaves. The 1542 reference is a signal that the employer is trying to buy a broader peace than just the known disputes.
Limits on Confidentiality and Non-Disparagement Clauses
Under California Government Code Section 12964.5, no provision in a separation agreement can prevent you from disclosing information about unlawful acts in the workplace — including harassment, discrimination, and retaliation of any kind, not just sex-based claims.5California Legislative Information. California Code GOV 12964.5 If the agreement includes a confidentiality or non-disparagement clause touching on workplace conditions, it must contain language substantially stating: “Nothing in this agreement prevents you from discussing or disclosing information about unlawful acts in the workplace, such as harassment or discrimination or any other conduct that you have reason to believe is unlawful.”
A clause that violates this rule is unenforceable as against public policy. The law doesn’t ban confidentiality or non-disparagement outright. An employer can still ask you not to disparage its products or disclose trade secrets. What it can’t do is use the agreement to buy your silence about illegal conduct.
Non-Compete Clauses Are Void
If the agreement contains a non-compete clause restricting where you can work after leaving, that clause is almost certainly unenforceable. Business and Professions Code Section 16600 declares any contract restraining someone from engaging in a lawful profession, trade, or business void, and courts are directed to read the prohibition broadly.6California Legislative Information. California Code BPC 16600
Section 16600.1, effective in 2024, made it affirmatively unlawful to include a non-compete in an employment contract. Employers had to send written notice by February 14, 2024 to current and former employees (employed after January 1, 2022) stating that any existing non-compete was void. Noncompliance is unfair competition carrying a civil penalty of up to $2,500 per violation.7California Legislative Information. California Code BPC 16600.1
A non-compete in a California separation agreement is void even if you sign it. Non-solicitation clauses (barring you from poaching clients or employees) and confidentiality clauses protecting trade secrets occupy a different legal space and may be enforceable depending on drafting.
How Much Time You Get to Review and Revoke
Both California and federal law set minimum review periods. The employer can’t shorten them.
California: Five Business Days
Under Government Code Section 12964.5, an employer offering a separation agreement must notify you of your right to consult an attorney and give you at least five business days to do so.5California Legislative Information. California Code GOV 12964.5 You can sign earlier if that decision is truly voluntary and the employer hasn’t pressured you by threatening to change terms or pull the offer.
Age 40 and Older: 21 or 45 Days, Plus a Seven-Day Revocation Window
If you’re 40 or older, the federal Older Workers Benefit Protection Act adds significantly more time. For an individual separation, you must get at least 21 days to consider the agreement. If the separation is part of a group layoff or exit incentive program, the period is 45 days.8Office of the Law Revision Counsel. 29 USC 626 – Recordkeeping, Investigation, and Enforcement The agreement must also advise you in writing to consult a lawyer before signing.9U.S. Equal Employment Opportunity Commission. Understanding Waivers of Discrimination Claims in Employee Severance Agreements
After signing, you have a mandatory seven-day revocation window during which you can cancel for any reason. The agreement doesn’t become effective or enforceable until those seven days pass without revocation.8Office of the Law Revision Counsel. 29 USC 626 – Recordkeeping, Investigation, and Enforcement Most employers hold severance payment until that window closes.
If the offer is part of a group layoff, the employer also has to give you a written description of the covered group, the eligibility criteria, applicable deadlines, and the job titles and ages of everyone selected along with the ages of employees in the same classification who were not selected. Missing those disclosures typically invalidates the age-discrimination waiver.
Final Paycheck vs. Severance: Two Different Timelines
Your earned wages and your severance travel on separate tracks. Confusing them is a common and expensive mistake.
Under Labor Code Section 201, if the employer fires you, all earned and unpaid wages are due immediately on the day of termination. That includes regular pay, accrued vacation, and earned commissions.10California Legislative Information. California Code Labor Code LAB 201 The employer cannot hold your final paycheck while waiting for you to sign the agreement or return equipment. California law prohibits conditioning wage payment on return of property.11Department of Industrial Relations. Deductions From Wages
If the employer misses the final-pay deadline, Labor Code Section 203 waiting-time penalties kick in. The penalty is your daily rate of pay for each day wages remain unpaid, capped at 30 calendar days (weekends and holidays included).12Department of Industrial Relations. Waiting Time Penalty For someone earning $300 a day, that’s up to $9,000 in penalties on top of the unpaid wages. The employer owes those wages whether you sign or not, which is why the real value of the separation agreement is only the severance that sits on top.
Severance itself follows the agreement’s terms. Most employers process payment within one to two pay cycles after the agreement becomes effective, meaning after any revocation period ends. There’s no statutory deadline for severance.
How Severance Is Taxed
Severance is taxable income in the year you receive it. The IRS treats it as supplemental wages and the employer reports it on your W-2.13Internal Revenue Service. Publication 4128 – Tax Impact of Job Loss
For federal purposes, the flat withholding rate on supplemental wages is 22 percent, rising to 37 percent on supplemental wages above $1 million in a year.14Internal Revenue Service. Publication 15, Employer’s Tax Guide California treats severance as a supplemental wage payment and, when paid as a lump sum separate from regular wages, the employer can withhold at a flat 6.6 percent.15Employment Development Department. Personal Income Tax Withholding – Supplemental Wage Payments Both are withholding estimates. Your actual tax depends on total income.
If part of the payment compensates for physical injuries or physical sickness, that portion may be excluded from taxable income under 26 U.S.C. § 104(a)(2).16Office of the Law Revision Counsel. 26 USC 104 – Compensation for Injuries or Sickness Emotional distress by itself doesn’t qualify as a physical injury, so payments for harassment or discrimination that caused anxiety without physical harm are fully taxable. The only carveout is the portion of an emotional-distress recovery that reimburses actual medical expenses you paid. How the agreement allocates the payment across claim categories directly affects your tax bill.
Unemployment Benefits and Severance
Accepting severance generally does not disqualify you from California unemployment insurance. The Employment Development Department does not treat severance as “wages” for UI purposes, relying on Unemployment Insurance Code Section 1265 and the California Supreme Court’s decision in Powell and Byrd v. California Unemployment Insurance Appeals Board.17Employment Development Department. Total and Partial Unemployment TPU 460.35
To qualify as severance rather than wages, the payment generally needs to be made under a plan or policy covering employees terminated for reasons like job elimination or reduction in force, with the purpose of bridging the gap to new employment. The EDD looks at substance, not labels. If the employer calls it “severance” but it’s really deferred compensation for past work, the EDD may treat it as wages and allocate it against your benefit period.17Employment Development Department. Total and Partial Unemployment TPU 460.35
Health Insurance and COBRA
If your employer has 20 or more employees, federal COBRA lets you continue the group health plan for up to 18 months after separation. You pay the full premium (employee and employer portions) plus a 2 percent administrative fee.18U.S. Department of Labor. COBRA Continuation Coverage
Some agreements include an employer contribution toward COBRA premiums for a specified number of months. If yours does, check when the subsidy ends and what your out-of-pocket cost becomes afterward. Confirm whether the employer pays premiums directly or reimburses you, because the tax treatment differs: direct payments are typically not taxable to you, while reimbursements may be.
What to Check Before You Sign
Confirm the severance exceeds what you’re already owed. Your final paycheck and accrued vacation are not consideration under Labor Code 201. If the package doesn’t add real value on top, the release may not hold up.
Watch for broad release language that tries to sweep in wage claims. Under Labor Code Section 206.5, a release of wage claims is void unless those wages have already been paid.2California Legislative Information. California Code LAB 206.5 If you think you’re owed unpaid overtime or commissions, don’t assume the general release covers them.
Ask for a neutral reference clause. Many agreements include language limiting what the employer will say to future employers (dates of employment and job title). It costs the employer nothing and can matter more than another week of severance.
Use the review period. An employment attorney can usually review a draft for a flat fee or a few billable hours, and that cost often pays for itself in a corrected clause or a better number. If you’re 40 or older, the agreement itself has to tell you in writing to consult a lawyer, and that advice is worth following.
