California labor laws on termination start from an at-will baseline and then narrow it heavily: employers can generally fire without cause, but cannot fire for a discriminatory or retaliatory reason, cannot skip final-pay deadlines, cannot ignore 60-day notice rules for mass layoffs, and cannot use a severance agreement to silence claims about unlawful workplace conduct. The penalties for getting any of this wrong — waiting-time pay, PAGA penalties, WARN back pay, FEHA damages, and attorney fees — routinely exceed the wages in dispute.
At-Will and the Exceptions That Actually Matter
Labor Code 2922 makes every employment relationship without a fixed term terminable at the will of either party. That is the baseline. It is also where most employer confusion begins, because several doctrines override it.
Implied Contracts
Written, oral, or implied agreements can defeat at-will status. A progressive discipline procedure in a handbook, or a manager telling a recruit “you’ll have a job here as long as you perform,” can become an enforceable promise. In Guz v. Bechtel National, Inc. (2000), the California Supreme Court held that implied contracts arising from company policies, length of service, or verbal assurances can require an employer to show good cause before terminating.1Justia Law. Guz v. Bechtel National Inc. Handbook language and offer letters need to say what the employer actually means them to say.
Public Policy
Even without any contract, Tameny v. Atlantic Richfield Co. (1980) recognized a tort claim for wrongful termination in violation of public policy. An employer cannot fire someone for refusing to break the law, reporting illegal conduct, exercising a legal right, or fulfilling a civic obligation such as jury service. Because the claim sounds in tort rather than contract, emotional distress and punitive damages are on the table.
Off-Duty Cannabis
Since January 1, 2024, Government Code 12954 has prohibited adverse action against employees or applicants for cannabis use off the job and away from the workplace, and prohibits acting on a drug test that detects only non-psychoactive cannabis metabolites.2California Legislative Information. California Government Code 12954 Employers can still prohibit use during work hours and test for current impairment. Building and construction trades and positions requiring federal background clearance are exempt.
Discriminatory Terminations Under FEHA
Government Code 12940 (the Fair Employment and Housing Act) prohibits terminating an employee because of race, sex, gender identity, age, disability, religion, sexual orientation, national origin, marital status, or military or veteran status. FEHA reaches employers with five or more employees, well below the federal fifteen-employee threshold, and covers categories such as gender identity and marital status that federal law does not.
Some firings draw closer scrutiny than others. Workers 40 and older are protected under FEHA and the federal Age Discrimination in Employment Act, and the California Civil Rights Department has stated that a need to cut costs does not justify targeting older, higher-paid employees while keeping younger, cheaper ones.3California Civil Rights Department. Age Discrimination in Employment Fact Sheet
Disability terminations require the employer to first engage in an interactive process to identify reasonable accommodations. The duty is affirmative, and the employer bears the burden of proving that any accommodation would cause undue hardship.4Cornell Law School. California Code of Regulations Title 2 Section 11068 – Reasonable Accommodation Firing a disabled employee without exploring modified duties, schedule changes, or assistive equipment is one of the surest ways to lose a lawsuit. The same principle governs pregnancy: job modifications or leave must be considered before termination.
Retaliation and Whistleblower Firings
Retaliation is among the most common bases for employment litigation in California, largely because the list of protected activities is long. FEHA prohibits firing employees for opposing unlawful workplace practices, filing complaints with the Civil Rights Department, or participating in investigations.5Justia. CACI No. 2505 – Retaliation Essential Factual Elements
Labor Code 1102.5 goes further. It protects any employee who reports what they reasonably believe to be a violation of state or federal law, whether the report goes to a government agency, a supervisor, or a coworker with authority to investigate. The employee does not need to be right about the violation. Employers who retaliate face civil penalties of up to $10,000 per employee per violation, plus reinstatement and lost wages.6California Legislative Information. California Labor Code 1102.5
Adverse action against employees who take California Family Rights Act leave or raise Cal/OSHA safety concerns runs into the same problem. State regulations bar using CFRA leave as a negative factor in any employment decision, including counting it against an employee under an attendance policy.7Cornell Law School. California Code of Regulations Title 2 Section 11094 – Retaliation and Protection from Interference with CFRA Rights Courts look at temporal proximity: when a firing closely follows a protected activity, an inference of retaliation arises. California’s Private Attorneys General Act then compounds the risk by letting one employee sue on behalf of all affected workers for Labor Code violations, spreading penalties across the workforce.8California Labor Agency. Private Attorneys General Act PAGA Frequently Asked Questions
When a Resignation Counts as a Firing
An employer does not escape liability by making an employee quit. If working conditions were so intolerable that a reasonable person in the employee’s position would have felt compelled to resign, and the employer intentionally created or knowingly permitted those conditions, California treats the resignation as a termination. Isolated incidents rarely qualify unless extreme; the typical constructive discharge case involves a sustained pattern of harassment, retaliation, or deliberate exclusion from duties.9Justia. CACI No. 2510 – Constructive Discharge Explained The remedies mirror those for any wrongful firing.
Final Paycheck Rules
This is where employers most often stumble, and the penalties are mechanical.
Timing
When you fire or lay off an employee, all earned wages are due immediately at the time of discharge. There is no grace period.10California Legislative Information. California Labor Code 201 An employee who resigns with at least 72 hours’ notice must be paid on the last day of work. An employee who quits without notice must be paid within 72 hours.11California Legislative Information. California Labor Code 202 Waiting for the next payroll cycle is not compliant.
Vacation
Accrued but unused vacation is treated as earned wages. It cannot be forfeited on termination and must be paid at the employee’s final rate.12California Legislative Information. California Labor Code 227.3 “Use it or lose it” policies are unlawful in California. Accrual caps are allowed; forfeiture of vested time is not.
Commissions
Commissions earned on or before the termination date go into the final check. Commissions not yet earned because a condition is unmet (for example, the customer has not paid) must be paid as soon as the condition is satisfied.13California Department of Industrial Relations. Paydays, Pay Periods, and the Final Wages
Deductions
You cannot dock the final paycheck to recover an unreturned laptop, training costs, or losses blamed on the employee. Labor Code 224 limits deductions to those required by law, those authorized in writing by the employee for insurance or benefit premiums, and those authorized by a collective bargaining agreement.14California Legislative Information. California Labor Code 224 If the employee owes you money, pursue it as a separate matter.
Waiting-Time Penalties
Willful failure to pay final wages on time costs the employer one day’s pay for each day the wages remain unpaid, up to 30 calendar days.15California Department of Industrial Relations. Waiting Time Penalty “Willful” does not require bad intent. Not having a system to pay on time qualifies. The only real defense is a good-faith dispute about whether the wages were owed at all. For a well-paid employee, 30 days of penalties can eclipse the unpaid wages themselves.
Mass Layoffs: California’s WARN Act
Labor Code sections 1400 through 1408 require 60 days’ written notice before a mass layoff, plant closure, or relocation at a covered establishment. A covered establishment is any industrial or commercial facility that employs, or has employed within the preceding 12 months, 75 or more people.16California Legislative Information. California Labor Code 1400 That threshold is lower than the 100-employee federal trigger. A qualifying relocation means moving all or substantially all operations 100 or more miles away.
Notice must reach affected employees, the Employment Development Department, the local workforce investment board, and the chief elected official of each city and county where the action occurs.17California Legislative Information. California Labor Code 1401 The only exception to the 60 days is a layoff caused by physical calamity or act of war.
An employer that skips notice owes each affected employee back pay at the higher of their average regular rate over the last three years or their final rate, plus the value of benefits that would have continued during the violation period. The liability runs for up to 60 days, or half the number of days the employee worked for the company, whichever is shorter.18California Legislative Information. California Labor Code 1402 For a sizable workforce reduction, the total can reach millions.
Severance Agreements
California does not require severance pay. When it is offered, though, the release has to comply with specific limits or it can be unenforceable.
What You Cannot Silence
Government Code 12964.5, enacted through SB 331 (the “Silenced No More Act”), bars separation agreements from prohibiting disclosure of information about unlawful workplace acts, including harassment and discrimination. Any non-disparagement or confidentiality clause that touches workplace conditions must include 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.”19LegiScan. California Senate Bill 331 Chaptered Trade secrets and the severance amount can still be kept confidential. Illegal conduct cannot.
The employer must also tell the employee of the right to consult an attorney and give at least five business days to do so. The employee may sign earlier if the choice is knowing and voluntary and not the product of pressure to withdraw the offer.
Releases from Employees 40 and Older
When the departing employee is 40 or older, any waiver of age discrimination claims must satisfy the federal Older Workers Benefit Protection Act. The agreement must reference the ADEA by name, use plain language, provide consideration beyond what the employee is already owed, and advise the employee in writing to consult an attorney. Individual waivers require a 21-day consideration period; group waivers tied to an exit incentive or layoff program require 45 days. In both cases the employee has 7 days after signing to revoke, and the revocation period cannot be shortened. Group waivers additionally require disclosure of the job titles and ages of employees eligible and ineligible for the program.20eCFR. 29 CFR 1625.22 – Waivers of Rights and Claims Under the ADEA Miss any step and the waiver fails, meaning the employee keeps the severance and keeps the right to sue.
What a Wrongful Termination Actually Costs
A successful wrongful termination plaintiff in California can recover:
- Back pay, meaning lost wages and benefits from termination through judgment, offset by earnings from replacement work.
- Front pay, meaning projected future lost earnings when reinstatement is impractical.
- Emotional distress damages, which California juries have valued in the six or seven figures in egregious cases.
- Punitive damages, available on a showing of malice, fraud, or oppression, and uncapped in many wrongful termination claims.
- Attorney fees, recoverable by a prevailing employee under FEHA and several Labor Code provisions, and often exceeding the underlying damages.
Reinstatement is possible but ordered less frequently than money. Labor Code 1102.5 specifically authorizes reinstatement for whistleblower claims along with lost wages and civil penalties.6California Legislative Information. California Labor Code 1102.5
After the Termination: Notices and Records
The compliance work does not end at the exit. California employers must immediately give written notice to any employee who is fired or laid off, informing them of their rights under state unemployment insurance, disability insurance, and paid family leave.21Employment Development Department. Required Notices and Pamphlets The notice is not required for voluntary quits, promotions, or demotions. If the employer provides group health insurance, federal law requires notifying the plan administrator of the qualifying event within 30 days, and the administrator then has 14 days to send the departing employee a COBRA election notice.22U.S. Department of Labor. FAQs on COBRA Continuation Health Coverage for Workers
Federal regulations require retaining personnel records of an involuntarily terminated employee for at least one year from the termination date, and all records relevant to any filed discrimination charge until the matter is resolved.23eCFR. 29 CFR Part 1602 – Recordkeeping and Reporting Requirements Under Title VII, the ADA, GINA, and the PWFA Under California law, a former employee can request to inspect and receive copies of their personnel file in writing, and the employer must provide copies within 30 calendar days at a cost not exceeding actual reproduction cost.24California Department of Industrial Relations. Personnel Files and Records A records request shortly after a termination is frequently the first sign that a lawsuit is coming. Respond on time and preserve everything.
