Can You Be Fired for a Complaint That Turns Out to Be Wrong? California Retaliation Law

Know Your Rights

The employer generally cannot defend retaliation simply by saying:

“We eventually concluded your original complaint wasn’t valid.”

The issue is whether the complaint was protected when it was made and whether the employer later took adverse action because of that protected conduct.

FEHA Protects Reasonable, Good-Faith Opposition

The California Supreme Court addressed this principle in Yanowitz v. L’Oreal USA, Inc. The court explained that retaliation protection can apply when an employee complains about or opposes conduct that the employee reasonably believes is discriminatory, even when the conduct is later determined not to violate FEHA.

That prevents an obvious problem:  If workers received protection only when they could ultimately prove every element of the underlying discrimination claim, employees would have to predict the outcome of future litigation before safely reporting misconduct. That would significantly discourage workplace complaints.

California Whistleblower Law Uses a Similar Concept

California Labor Code section 1102.5 protects certain employees who disclose information when they have reasonable cause to believe the information reveals a violation of a state or federal statute or a violation or noncompliance with a local, state, or federal rule or regulation. Again, the statute focuses on the employee’s reasonable basis for reporting suspected unlawful conduct.

A 2025 Court of Appeal decision, Contreras v. Green Thumb Produce, specifically recognized that an employee’s mistaken interpretation does not necessarily defeat a section 1102.5 retaliation claim. The belief still must satisfy an objective reasonableness requirement.

The Complaint Does Not Have to Use Legal Language

Employees are not expected to write workplace complaints like lawyers. An employee does not necessarily have to say: “I hereby lodge a complaint pursuant to Government Code section 12940.”

Rather, real employees say things like: “My supervisor keeps making comments about my age.” “I think I’m being treated differently because I’m pregnant.” “I think we’re being told to do something illegal.” “They aren’t paying us for all of our hours.” “This doesn’t seem safe.”

Whether the communication constitutes protected activity depends on its substance and the applicable statute, not whether the employee correctly cites a code section.

But Not Every Complaint Is Protected Activity

There is another side to this rule.

Merely complaining about something unpleasant does not automatically invoke retaliation protection. For example: “My supervisor is annoying.” “I don’t like my schedule.” “I deserved the promotion.” “My manager favors another employee.” Those complaints, standing alone, do not necessarily identify conduct protected by a retaliation statute. The complaint ordinarily needs some connection to legally protected conduct.

Likewise, the law’s reasonable-belief requirement matters. The protection is not simply: “I accused my employer of anything, therefore nothing can happen to me.” The facts and the employee’s basis for making the complaint still matter.

Example — The Discrimination Complaint That Cannot Be Proven

Consider an employee who is over 40.

Her supervisor repeatedly makes comments about wanting “younger energy” in the department and asks when she plans to retire.

The employee complains to HR that she believes she is experiencing age discrimination. HR investigates but concludes there is insufficient evidence that any actual employment decision was based on age.

Two weeks after the complaint, the employee receives the first negative write-up of her career. A month later, she is fired for supposedly longstanding performance problems. Even if the employee ultimately cannot establish that the employer actually discriminated against her based on age, that does not necessarily resolve the retaliation claim. The relevant questions include:

Was her original complaint objectively reasonable and made in good faith?

Who knew about it?

What happened afterward?

Why was she terminated?

Did her performance history change only after the complaint?

Did the employer’s explanation change?

Those questions involve retaliation independently of whether the original discrimination allegation ultimately succeeds.

Timing Can Become Powerful Evidence

Imagine this sequence:

January 10: Employee complains.

January 17: Supervisor learns about complaint.

January 25: First disciplinary notice.

February 3: Schedule reduced.

February 15: Employee placed on performance improvement plan.

March 1: Employee fired.

That chronology does not automatically prove retaliation. But it gives an attorney a roadmap. The tighter the relationship between the protected complaint and adverse action, the more closely the employer’s explanation should be examined.

What Other Evidence Should Be Examined?

Retaliation cases often depend on circumstantial evidence.

Important evidence can include:

• The employee’s performance history before the complaint
• Sudden write-ups afterward
• Emails between managers
• Text messages
• HR communications
• Statements concerning the complaint
• Scheduling changes
• Reduced hours
• Demotions
• Performance improvement plans
• Comparator employees
• Shifting explanations for termination
• The identity of the decision-makers

A retaliation case is often built by comparing before the complaint with after the complaint.

When Retaliation Leads to Termination

If the adverse action is termination, the employee may have overlapping claims. Depending on the circumstances, that can include a statutory retaliation claim and potentially a claim for wrongful termination in violation of public policy.

The precise claims depend on what protected activity occurred, which statute protects it, and what caused the termination. The important point is that an employee does not necessarily lose retaliation protection simply because the original workplace complaint was not ultimately proven correct.

What Should an Employee Do After Making a Complaint?

Preserve the chronology.

Keep lawful copies of the complaint.

Save the employer’s response.

Record the date management learned about it.

Preserve performance evaluations from before the complaint.

Keep later disciplinary notices.

Identify witnesses.

And document what changed. If the employee is eventually terminated, the history of what happened between the complaint and the termination can become some of the most important evidence in the case.
