You raised something at work — unpaid overtime, a safety hazard, harassment, billing that looked fraudulent — and not long after, you were written up, reassigned, or fired. Your employer says the two things are unrelated.

Proving otherwise is the entire game in a retaliation case. The good news is that California law has moved substantially in employees’ favor on exactly this point in recent years, and the burden your employer now carries is heavier than most people realize.

The Three Elements

Every California retaliation claim, whatever statute it arises under, comes down to three things:

1. You engaged in protected activity.
2. Your employer took an adverse action against you.
3. There is a causal connection between the two.

Elements one and two are usually straightforward. Element three is where cases are won.

Element 1: Was Your Complaint Protected?

Broader than most employees assume. Protected activity in California includes:

• Reporting suspected legal violations — Labor Code §1102.5. This is the big one. It protects disclosures to a government agency, to law enforcement, and — since 2014 — internally, to a supervisor or someone with authority to investigate. You do not have to go outside the company to be protected. You also do not have to be right: you need reasonable cause to believe the conduct was unlawful. An employee who reports in good faith and turns out to be mistaken is still protected.
• Complaining about discrimination or harassment — FEHA, Government Code §12940(h). Including on behalf of someone else, and including participating in an investigation.
• Wage and hour complaints — Labor Code §98.6. Including complaints made only to the employer.
• Health and safety complaints — Labor Code §6310.
• Requesting an accommodation or taking protected leave.
• Discussing your wages or working conditions with coworkers — Labor Code §§232, 232.5.

You do not need to have used the words “illegal,” “discrimination,” or “retaliation.” Employers argue constantly that a complaint was just a generalized gripe. What matters is whether the substance of what you raised put the employer on notice of the conduct at issue.

Element 2: What Counts as an Adverse Action?

Not just termination. California applies a broad standard covering anything that materially affects the terms, conditions, or privileges of employment:

• Firing, demotion, or a pay cut
• A sudden negative review or first-ever write-up
• Being placed on a performance improvement plan
• Losing accounts, territory, shifts, or overtime
• Schedule changes designed to be unworkable
• Reassignment to a materially worse role
• Exclusion from meetings, projects, or training you previously had
• A pattern of smaller actions that add up, even where no single one would qualify

Constructive discharge — conditions made so intolerable that a reasonable person would resign — can also qualify, though it carries a high bar.

Element 3: Proving Causation

Employers rarely put retaliation in writing. Almost every case is built on circumstantial evidence, and California law now gives employees several structural advantages.

The 90-day presumption

This is the most significant recent development. Under SB 497, effective January 1, 2024, if an employer disciplines or discharges an employee within 90 days of protected activity under Labor Code §§98.6, 1102.5, or 1197.5, retaliation is presumed. The burden shifts to the employer to articulate a legitimate, non-retaliatory reason.

Practically: pin down the exact date you complained and the exact date the adverse action occurred. If the gap is under 90 days, your case starts from a materially stronger position.

The employer’s burden under Labor Code §1102.6

For whistleblower claims, California does not use the familiar federal McDonnell Douglas burden-shifting test. The California Supreme Court confirmed this in Lawson v. PPG Architectural Finishes (2022).

Under §1102.6, once you show by a preponderance of the evidence that your protected activity was a contributing factor — not the only reason, not even the main reason — the employer must then prove by clear and convincing evidence that it would have taken the same action anyway for legitimate, independent reasons.

Two things about that are worth sitting with. “Contributing factor” is a low threshold for you. “Clear and convincing evidence” is a demanding standard for them — well above the ordinary civil standard. A mixed-motive termination, where retaliation was one of several reasons, is a losing position for an employer under this framework.

Pretext: showing the stated reason isn’t the real one

The evidence that does the most work:

• Shifting explanations. One reason at termination, a different one to the EDD, a third in litigation. Inconsistency is powerful evidence, which is why getting the reason in writing at the time matters so much.
• A clean record that suddenly isn’t. Years of strong reviews, then a first write-up weeks after your complaint.
• Comparators. Employees who did the same thing or worse — but did not complain — and kept their jobs.
• Departures from the employer’s own process. A handbook that promises progressive discipline, skipped entirely in your case.
• Manufactured documentation. Write-ups dated before termination that you never saw or signed. This is common, and metadata frequently exposes when a document was actually created.
• Knowledge. The decision-maker must have known about your protected activity. Evidence that HR told your manager, or that the complaint was discussed, closes that loop.
• Changed treatment. Sudden exclusion, scrutiny, or hostility that began after the complaint — often the thing coworkers noticed too.

The “cat’s paw” problem

Employers sometimes route the decision through someone with no knowledge of the complaint. That does not necessarily insulate them: where a biased supervisor influenced or engineered the decision, the retaliatory motive can be attributed to the employer even though the formal decision-maker was innocent.

What to Do Right Now

1. Fix the dates. The date of every complaint, in writing where possible, and the date of every adverse action.
2. Request your personnel file in writing under Labor Code §1198.5. The employer generally must produce it within 30 days — and what is in it, particularly discipline you have never seen, is often decisive.
3. Get the stated reason in writing before it changes.
4. Preserve your own records — your reviews, your emails, your texts. Do not take the company’s confidential files; that creates a counterclaim and shifts the case onto your conduct instead of theirs.
5. Write down witnesses with non-work contact information.
6. Watch the administrative deadline. FEHA retaliation claims generally require a complaint to the California Civil Rights Department within three years, then suit within one year of the right-to-sue notice. Labor Code §1102.5 claims generally carry a three-year period.

What You Can Recover

• Lost wages and benefits, past and future
• Emotional distress damages
• Punitive damages where the employer acted with malice, oppression, or fraud
• Attorney’s fees — available to prevailing plaintiffs under FEHA and, in the court’s discretion, under Labor Code §1102.5
• A civil penalty of up to $10,000 per violation under Labor Code §1102.5, payable to the employee
• Reinstatement, in appropriate cases

Keep in mind that you have a duty to mitigate — to look for comparable work — and that your job search records will be discoverable.
