What Proving Wrongful Termination in California Looks Like

Legally reviewed by: Jessica Anvar Stotz, JD, MBA

Short answer: To prove wrongful termination in California, you must show your firing broke a law, contract, or public policy.

Proving California Wrongful Termination Overview

Here are the key ways to prove wrongful termination in California:

1. Establish that the termination violated public policy (e.g., you were fired for refusing to do something illegal, reporting workplace harassment, or exercising a legal right like taking medical leave)
2. Demonstrate discrimination based on protected characteristics such as race, gender, age, disability, sexual orientation, or other legally protected status
3. Show evidence of retaliation, such as being fired after whistleblowing, filing a workplace complaint, or participating in an investigation about workplace misconduct
4. Prove that the termination breached an existing employment contract or violated the terms of your employment agreement
5. Gather documentation including emails, performance reviews, witness statements, and other evidence that supports your claim of improper or illegal reasons for termination

Remember that California is an at-will employment state, so the burden of proof is on you to show that the termination was specifically illegal or violated your rights.

Employment Lawyer’s Feedback

This is fictitious employment lawyer feedback for informational purposes.

“Without contemporaneous documentation, witness statements, or evidence of discriminatory treatment, we can’t establish that your termination was wrongful rather than performance-based. The company has documented progressive discipline, and we have no evidence to counter their narrative.”

This case highlights the importance of:

• Immediately documenting incidents
• Following proper reporting procedures
• Maintaining copies of all documentation
• Responding professionally to discipline
• Gathering comparative evidence
• Securing witness statements
• Creating clear, factual timelines
• Saving all communications

8 Most Common Mistakes to Avoid When Trying to Prove Wrongful Termination in CA

Below are the 8 common mistakes to avoid when trying to prove wrongful termination:

1. Failing to document everything systematically and thoroughly, including losing or destroying potential evidence that could support your case
2. Discussing your case inappropriately on social media or with coworkers, which can potentially damage your credibility or provide ammunition for your employer’s defense
3. Waiting too long to take action, as California has strict statutes of limitations for filing wrongful termination claims (typically between 6 months to 3 years depending on the specific type of claim)
4. Exaggerating or fabricating evidence, which can completely undermine your entire legal case and potentially expose you to counter-legal action
5. Not preserving your professional reputation by continuing to act professionally during and after the termination, as your overall conduct can be scrutinized during legal proceedings
6. Failing to consult with an employment law attorney who can provide expert guidance on the strength of your specific case and help you navigate complex legal procedures
7. Assuming that being fired automatically means you have a winnable wrongful termination case, when in reality, California is an at-will employment state with specific legal standards for proving improper termination
8. Neglecting to file initial complaints with appropriate state agencies like the Department of Fair Employment and Housing (DFEH) before pursuing litigation
