How to Prove Wrongful Termination in California

Getting fired feels devastating. But if you believe your termination was illegal, you have rights under California law. The question is: how do you prove it?

Proving wrongful termination is not as simple as showing you were treated unfairly. California is an at-will employment state, which means employers can fire you for almost any reason—or no reason at all. But there are important exceptions.

To win a wrongful termination case, you need to prove your firing violated California or federal law. The evidence you need depends on what type of claim you’re making.

This guide explains how to build a strong wrongful termination case in California, step by step.

What You Need to Prove Depends on Your Claim Type

Not all wrongful termination cases are the same. California recognizes several types of illegal firing:

  • Discrimination (based on protected characteristics like race, gender, age, disability)
  • Retaliation (firing you for protected activities like reporting harassment or filing a workers’ comp claim)
  • Violation of public policy (firing you for refusing to break the law or exercising a legal right)
  • Breach of implied contract (firing you despite promises of job security)

Each type of claim requires different proof. Here’s what you need to know for each one.

Burden of Proof by Claim Type

Discrimination Claims Under FEHA

If you believe you were fired because of your race, gender, age, disability, religion, or another protected characteristic, you’re making a discrimination claim under California’s Fair Employment and Housing Act (FEHA).

California courts use the McDonnell Douglas burden-shifting framework to evaluate these cases. This three-step process determines whether discrimination occurred:

Step 1: You prove a “prima facie case”

You must show four basic facts:

  1. You belong to a protected class
  2. You were qualified for your job
  3. You suffered an adverse action (termination)
  4. Similar employees outside your protected class were treated better

Step 2: Employer provides a legitimate reason

Once you establish your prima facie case, the burden shifts to your employer. They must provide a legitimate, non-discriminatory reason for firing you.

Step 3: You prove the reason is “pretext”

If your employer provides a reason, you must prove it’s false or pretextual. This means showing their stated reason is a cover-up for discrimination.

Retaliation Claims

Retaliation claims follow the same McDonnell Douglas framework. You must prove:

  1. You engaged in a protected activity (like complaining about harassment, filing a wage claim, or taking protected leave)
  2. Your employer took adverse action against you (termination)
  3. There’s a causal connection between your protected activity and your firing

California courts look at timing, pattern, and pretext to establish this causal connection.

Public Policy Violations

California recognizes wrongful termination when you’re fired for reasons that violate public policy. This includes:

  • Refusing to break the law
  • Performing a legal duty (like jury service)
  • Exercising a legal right (like taking family leave or filing a workers’ comp claim)

To prove a public policy claim, you must show:

  1. A fundamental public policy exists
  2. Your termination would undermine that policy
  3. The policy violation was a substantial motivating reason for your firing

Breach of Implied Contract

Even without a written employment contract, you might have an implied contract based on:

  • Employee handbook language
  • Verbal promises from management
  • Established company practices

To prove breach of implied contract, you must show:

  1. An implied contract existed
  2. Your employer breached it by firing you
  3. You suffered damages

Types of Evidence That Prove Wrongful Termination

Evidence in wrongful termination cases falls into four categories:

1. Direct Evidence (Rare but Powerful)

Direct evidence proves discrimination or retaliation without inference. This is the “smoking gun.”

Examples:

  • Email from your manager saying “We need younger employees”
  • Text message saying “I’m firing you for filing that harassment complaint”
  • Recorded statement admitting discriminatory motive

Direct evidence is rare. Most cases rely on circumstantial evidence.

2. Circumstantial Evidence (Most Common)

Circumstantial evidence requires inference to prove wrongful termination. It includes:

  • Timing: You filed a complaint on Monday and were fired on Wednesday
  • Pattern: Three employees over 50 were fired and replaced with younger workers
  • Comparator evidence: You were fired for being 10 minutes late once, but your coworker (different protected class) was never disciplined despite being late regularly
  • Pretext: Your employer claims you were fired for poor performance, but your reviews were always excellent

California courts look at the “totality of circumstances” when evaluating circumstantial evidence.

3. Documentary Evidence

Documents create a paper trail. Gather these items:

  • Performance reviews: Show you were meeting or exceeding expectations
  • Emails and text messages: Communication with supervisors, HR, or coworkers about discrimination, harassment, or complaints
  • Employee handbook: Provisions about progressive discipline or termination procedures
  • Termination letter: Your employer’s stated reason for firing you
  • DFEH complaint: If you filed with the Department of Fair Employment and Housing
  • Witness statements: Written accounts from coworkers who observed discrimination or retaliation
  • Pay stubs and personnel file: Document your employment history

4. Witness Testimony

People who saw what happened can testify:

  • Coworkers: Who heard discriminatory comments or observed unequal treatment
  • Customers or clients: Who witnessed harassment or discrimination
  • Expert witnesses: Employment law experts who can explain industry standards or statistical patterns

The McDonnell Douglas Framework Explained

Because most discrimination and retaliation cases use the McDonnell Douglas framework, let’s break it down further.

Establishing Your Prima Facie Case

The prima facie case is your initial burden. You don’t need to prove discrimination at this stage—just show enough evidence to raise an inference of discrimination.

Example: Maria, a 55-year-old Latina woman, was fired from her sales job. She can establish a prima facie case by showing:

  1. She’s in a protected class (age 40+, Latina, female)
  2. She met her sales quotas consistently
  3. She was terminated
  4. She was replaced by a 28-year-old white man

This doesn’t prove discrimination yet, but it’s enough to shift the burden to the employer.

Employer’s Legitimate Reason

Once you establish your prima facie case, your employer must provide a legitimate, non-discriminatory reason for firing you.

Example: Maria’s employer claims she was fired for “failure to follow company procedures” related to expense reporting.

This reason must be clear and specific. Vague explanations like “not a good fit” are weaker.

Proving Pretext

Pretext is where most wrongful termination cases are won or lost. You must show your employer’s stated reason is false, inconsistent, or a cover-up.

Ways to prove pretext:

  • The reason is factually false: You have records proving you followed all expense reporting procedures
  • The reason wasn’t the real reason: Your employer never mentioned expense issues before your termination
  • The reason is applied inconsistently: Other employees made similar expense errors but weren’t fired
  • Temporal proximity: You were fired days after complaining about age discrimination
  • Shifting explanations: Your employer gave different reasons for your termination at different times

Example: Maria can prove pretext by showing:

  • Her expense reports were identical to her coworkers’ reports
  • She never received warnings about expense reporting
  • Two weeks before her firing, she complained to HR about her manager’s comments about “making room for fresh talent”
  • Her replacement was hired three days after her termination—suggesting the decision was already made

Key Evidence to Gather Immediately

If you believe you were wrongfully terminated, start gathering evidence right away.

Performance Documentation

Collect all performance reviews, awards, bonuses, and positive feedback. These prove you were a qualified employee meeting expectations.

Electronic Communications

Download or save:

  • Emails between you and your supervisor
  • Text messages related to work
  • Slack or Teams messages
  • Any communication about complaints you made

Important: Do this while you still have access to company systems. Once you’re terminated, you may lose access.

Termination Documents

Request and keep copies of:

  • Termination letter
  • Final paycheck stub
  • Notice of rights (COBRA, unemployment)
  • Any severance agreement (don’t sign without legal review)

Timeline of Events

Create a detailed timeline documenting:

  • When you engaged in protected activity (complaints, leave requests, etc.)
  • When you noticed discriminatory treatment
  • Dates of negative performance feedback
  • Date of termination
  • Any relevant events before and after

Comparator Evidence

Identify employees outside your protected class who:

  • Committed similar violations but weren’t fired
  • Had worse performance but kept their jobs
  • Received warnings or progressive discipline instead of immediate termination

This evidence is powerful in discrimination cases.

Witness Information

Write down names and contact information for:

  • Coworkers who witnessed discrimination
  • People who heard discriminatory comments
  • Anyone who can support your version of events

Note: Contact witnesses while events are fresh in their memory.

Temporal Proximity: When Timing Tells the Story

In retaliation cases, timing is critical. “Temporal proximity” refers to how close in time your protected activity and termination occurred.

Strong temporal proximity:

  • You filed a harassment complaint on Monday and were fired on Friday
  • You returned from FMLA leave and were terminated the next week
  • You reported safety violations and were fired within days

California courts have found that temporal proximity alone can establish causation when the time between events is very short.

Example: In Yanowitz v. L’Oreal USA, Inc., an employee was fired shortly after refusing to fire a woman based on appearance. The California Supreme Court found the close timing supported a causal connection.

Weaker temporal proximity:

  • Several months pass between protected activity and termination
  • Multiple intervening events occur
  • Your employer documents legitimate performance issues during that time

However, even longer time periods can support retaliation claims if combined with other evidence of pretext.

What NOT to Do: Avoiding Common Mistakes

Don’t Destroy Evidence (Spoliation)

Never delete emails, texts, or documents related to your case. Destroying evidence can result in:

  • Sanctions from the court
  • Negative inferences drawn against you
  • Damage to your credibility

Be Careful on Social Media

Don’t post about your case on social media. Defense attorneys will search your profiles for:

  • Posts that contradict your claims
  • Evidence you’re not suffering emotional distress
  • Information to attack your credibility

Set all profiles to private and avoid posting about your termination or legal case.

Don’t Violate Confidentiality Agreements

Be careful about what documents you take and share. Some company information may be confidential. Consult with an attorney about what you can legally preserve and use.

Don’t Wait Too Long

California has strict deadlines for wrongful termination claims:

  • FEHA claims: You must file a complaint with DFEH within three years of the discriminatory act
  • DFEH Right-to-Sue notice: You must file in court within one year after DFEH issues a Right-to-Sue notice
  • Public policy claims: Generally two years under California’s statute of limitations
  • Breach of contract claims: Generally two to four years depending on contract type

Don’t wait. Evidence disappears, witnesses forget, and deadlines expire.

Real-World Examples: Strong vs. Weak Cases

Example 1: Strong Discrimination Case

Facts: James, a 62-year-old Black engineer, was fired after 15 years with excellent performance reviews. Three weeks before his termination, his new manager (age 35) said in a meeting “We need to bring in fresh perspectives.” James was replaced by a 29-year-old white employee with less experience.

Evidence:

  • Direct evidence: Witness testimony about “fresh perspectives” comment
  • Performance reviews showing consistent excellence
  • Comparator evidence: Younger engineer with similar minor errors wasn’t disciplined
  • Temporal proximity: Comment made weeks before termination

Outcome: Strong case. The “fresh perspectives” comment is direct evidence of age discrimination, supported by circumstantial evidence.

Example 2: Strong Retaliation Case

Facts: Sarah complained to HR about sexual harassment by her supervisor on March 1. HR conducted a brief investigation. On March 15, Sarah was fired for “insubordination” based on an incident from February 20 that was never previously mentioned.

Evidence:

  • Timeline showing complaint followed by termination
  • No prior documentation of “insubordination”
  • The February incident wasn’t mentioned in her February performance review
  • Harasser remained employed

Outcome: Strong case. Temporal proximity + pretext (undocumented, never-mentioned incident from before complaint) + failure to discipline harasser all support retaliation.

Example 3: Weak Discrimination Case

Facts: Maria, a Latina employee, was fired after six months for poor performance. She received two written warnings about missed deadlines before termination. She believes discrimination occurred because her manager is white.

Evidence:

  • Performance warnings documented before termination
  • No discriminatory comments or direct evidence
  • No comparator evidence (no similar employees treated differently)
  • Progressive discipline was followed

Outcome: Weak case. Without evidence of discriminatory motive, unequal treatment, or pretext, documented performance issues provide a legitimate reason for termination.

Example 4: Moderate Public Policy Case

Facts: John was fired two months after serving on jury duty. His employer said he was fired for “downsizing.” However, his position was filled by a new hire three weeks later.

Evidence:

  • Termination followed jury service
  • “Downsizing” reason contradicted by immediate replacement
  • California public policy protects jury service

Outcome: Moderate case. The false “downsizing” reason suggests pretext, and jury service is clearly protected. However, the two-month gap weakens temporal proximity. Case strength depends on additional evidence of causal connection.

Example 5: Weak Implied Contract Case

Facts: Angela worked for a company for three years. She was terminated without warning. The employee handbook says “employment is at-will” on every page.

Evidence:

  • No written contract
  • Handbook explicitly states at-will employment
  • No verbal promises of job security documented
  • No established practice of progressive discipline

Outcome: Weak case. Clear at-will language defeats implied contract claims unless there’s very strong evidence of contrary promises or practices.

Step-by-Step: Building Your Wrongful Termination Case

Step 1: Document Everything Immediately

As soon as possible after termination:

  • Write down everything that happened
  • Gather all documents while you have access
  • Save emails and electronic communications
  • Create a detailed timeline

Step 2: Identify Your Legal Theory

Determine what type of wrongful termination claim you have:

  • Discrimination based on protected characteristic
  • Retaliation for protected activity
  • Public policy violation
  • Breach of implied contract

You may have multiple claims.

Step 3: Gather Evidence by Claim Type

For discrimination/retaliation claims:

  • Evidence you’re in a protected class or engaged in protected activity
  • Documentation of your qualifications
  • Comparator evidence
  • Discriminatory comments or conduct
  • Evidence of pretext

For public policy claims:

  • Evidence of the protected activity (jury duty notice, workers’ comp claim, etc.)
  • Timeline showing termination followed protected activity
  • Evidence employer’s stated reason is false

For breach of implied contract:

  • Employee handbook provisions
  • Written or email promises
  • Evidence of company practices

Step 4: Identify Witnesses

Make a list of everyone who:

  • Witnessed discriminatory conduct
  • Heard discriminatory comments
  • Can verify your version of events
  • Can testify about unequal treatment

Contact them while memories are fresh.

Step 5: File Administrative Claims When Required

For FEHA discrimination or retaliation claims:

  • File a complaint with the California Department of Fair Employment and Housing (DFEH) or the federal EEOC
  • You must exhaust administrative remedies before filing in court
  • The agency will investigate and issue a Right-to-Sue notice

For other claims (public policy, breach of contract):

  • Administrative filing may not be required
  • Consult an attorney about proper procedures

Step 6: Consult an Employment Attorney

Wrongful termination cases are complex. An experienced employment attorney can:

  • Evaluate the strength of your case
  • Identify all potential claims
  • Navigate administrative requirements
  • Negotiate settlement or represent you in court

Many employment attorneys work on contingency (no fee unless you win).

Step 7: Preserve Evidence

Continue documenting:

  • Your job search efforts
  • Lost wages and benefits
  • Emotional distress and medical treatment
  • Any reputational harm

This evidence supports your damages claim.

Frequently Asked Questions

Do I need a smoking gun to prove wrongful termination?

No. While direct evidence like discriminatory emails is powerful, most cases are proven with circumstantial evidence. Timing, pattern, pretext, and comparator evidence can be enough to win.

How long do I have to file a wrongful termination claim in California?

It depends on your claim type. FEHA claims require filing with DFEH within three years, then filing in court within one year of receiving a Right-to-Sue notice. Public policy claims generally have a two-year statute of limitations. Consult an attorney immediately to avoid missing deadlines.

Can I prove wrongful termination if I was an at-will employee?

Yes. At-will employment means you can be fired for almost any reason, but not for illegal reasons. Discrimination, retaliation, and public policy violations are illegal even for at-will employees.

What if I signed a severance agreement?

Read it carefully before signing. Severance agreements often include releases that waive your right to sue. Once signed, you may lose your claims. Never sign a severance agreement without having an employment attorney review it first.

What damages can I recover in a wrongful termination case?

California law allows recovery of:

  • Lost wages: Past and future income you would have earned
  • Lost benefits: Health insurance, retirement contributions, stock options
  • Emotional distress: Compensation for psychological harm
  • Punitive damages: In cases of malicious conduct (discrimination/retaliation cases)
  • Attorney’s fees: In FEHA and some public policy cases

Damages vary widely based on your circumstances and the strength of your case.
