How Do You Prove Wrongful Termination

Short answer: to prove wrongful termination in California you have to show that the real reason for your firing was an unlawful one. Being fired without cause is legal in an at-will state; being fired because of a protected characteristic, because you complained about discrimination, harassment, wages or safety, because you requested leave or an accommodation, because you filed a workers’ compensation claim, or in violation of public policy is not. The proof is almost always circumstantial: timing, documents, comparisons and the employer’s own shifting story.

What wrongful termination is, and is not

California employment is at will (Labor Code section 2922). An employer may fire you for a bad reason or no reason, so a termination that seems unfair is not automatically unlawful. Wrongful termination means the firing violated a statute, a fundamental public policy or a contract. The most common types are:

• discrimination because of race, sex, age (40 and over), disability, pregnancy, national origin, religion, sexual orientation, gender identity or another protected characteristic (Government Code section 12940(a));
• retaliation for complaining about discrimination or harassment, requesting accommodation or leave, reporting unpaid wages or unsafe conditions, refusing to break the law, or reporting a violation of law (Government Code section 12940(h); Labor Code sections 98.6, 1102.5 and 6310);
• retaliation for filing a workers’ compensation claim (Labor Code section 132a);
• termination for taking protected leave under CFRA, pregnancy disability leave or FMLA;
• wrongful termination in violation of public policy, the common law claim for firings that offend a fundamental policy expressed in a statute or constitution;
• breach of an express or implied employment contract that limited the employer’s right to fire.

The evidence that proves it

• Timing. A termination days or weeks after a complaint, a leave request, a pregnancy announcement, a doctor’s note or a workers’ compensation claim is the most common evidence of motive.
• Your record. Good reviews, raises and promotions before the protected activity, followed by sudden criticism, write-ups or a performance improvement plan.
• The employer’s explanation. A reason that changed over time, that was never documented, that contradicts your record, or that the employer did not apply to others.
• Comparators. Coworkers who did the same thing and were not fired, or who were treated better and do not share your protected characteristic.
• Statements. Comments by managers about your age, condition, pregnancy, complaint or claim, in person, by email or by text.
• Policy deviations. Skipping progressive discipline, ignoring the handbook, or failing to investigate.
• Documents. Your written complaint, the doctor’s note, the leave request, the DWC-1 claim form, the termination letter, and your personnel file, which the employer must provide within 30 days of a written request (Labor Code section 1198.5).

Where the claim is filed

For discrimination, harassment, retaliation, accommodation and leave claims under FEHA, a complaint must be filed with the California Civil Rights Department (CRD) within three years of the termination (Government Code section 12960), and the lawsuit filed within one year of the right-to-sue notice (section 12965). An EEOC charge for federal claims must be filed within 300 days, and the federal suit within 90 days of the EEOC notice. Wrongful termination in violation of public policy is filed directly in court within two years (Code of Civil Procedure section 335.1); statutory Labor Code retaliation claims such as section 1102.5 are also filed directly in court, generally within three years (Code of Civil Procedure section 338(a)). A Labor Code section 132a petition is filed with the Workers’ Compensation Appeals Board within one year.

What you can recover

Lost wages and benefits from the termination forward, front pay where reinstatement is not practical, emotional distress damages, punitive damages where the employer acted with malice or oppression, reinstatement in some cases, and attorney fees under FEHA and many Labor Code provisions. Medical expenses are not a typical wrongful termination remedy unless the termination caused a medical condition.

Steps to take now

1. Write a timeline while it is fresh: what you complained about or requested, to whom, when, and what happened afterward.
2. Request your personnel file and payroll records in writing.
3. Gather what you legitimately have: emails and texts to you, reviews, the termination letter, offer letter and handbook. Do not take confidential company documents.
4. Apply for unemployment and keep records of your job search; mitigation matters to damages.
5. Do not sign a severance agreement without review; the law gives you at least five business days.
6. Talk to a lawyer before the deadlines run.
