California employers often focus on whether an employee’s complaint has legal merit. That instinct makes sense. If the complaint is wrong, exaggerated, or based on a misunderstanding of the law, it is easy to assume the risk is low.

That assumption is where employers get into trouble.

A recent California Court of Appeal decision makes the point. In Contreras v. Green Thumb Produce, Inc., the court confirmed that an employee can pursue a retaliation claim even when the underlying complaint is legally incorrect, so long as the employee reasonably believed a violation of law occurred.

That is the disconnect employers often miss.

The Shift Employers Need to Understand

Under California law, an employee engages in protected activity when they complain about conduct they reasonably believe violates the law. That belief does not have to be correct. It only needs to be “reasonable.”

An employee may complain about something that is not actually unlawful. They may misunderstand wage and hour rules, misapply harassment standards, or assume unfair treatment is illegal discrimination. Even if the complaint is legally flawed, it can still trigger protection.

Once that protection is in play, the employer’s next steps matter more than the accuracy of the complaint itself.

Where Employers Get It Wrong

There are a few predictable missteps we continue to see.

Often, employers focus too heavily on proving the employee wrong. They investigate, determine there was no legal violation, and then move on as if the issue is resolved, even though it isn’t.

Employers also can allow frustration to influence their decision making. Managers may view the complaint as disruptive, unnecessary, or strategic. That frustration can show up in tone, documentation, and ultimately employment decisions.

Finally, timing can be a problem. Discipline or termination that follows closely after a complaint will almost always be scrutinized. Even when there are legitimate reasons, the optics are difficult and the burden on the employer becomes heavier.

The Real Risk Is the Response

The legal analysis in these cases often turns on the employer’s response, not the underlying complaint.

• Did the employer take the concern seriously?
• Did they conduct a fair and neutral investigation?
• Did they separate the complaint from subsequent employment decisions?
• Did they document legitimate business reasons clearly and consistently?

If the answer to any of these questions is “no,” the employer’s position becomes harder to defend.

In practice, juries often are less interested in whether the employee understood the law correctly and more interested in whether the employer acted fairly.

A Practical Framework That Holds Up

Employers do not need to treat every complaint as valid. They do need to treat every complaint as protected until proven otherwise.

A few practical steps make a significant difference:

• Pause before reacting. Train managers not to respond in the moment. Initial reactions are often what create risk.
• Investigate the complaint, not the employee. The goal is to understand what happened, not to discredit the person who raised the concern.
• Document the analysis. If the complaint is not legally supported, explain why in a clear, objective way. Avoid language that suggests the complaint was frivolous or made in bad faith unless you can truly support that conclusion.
• Separate decision making. If there are performance or conduct issues, make sure they are well documented and existed before the complaint or are clearly independent of it.
• Control the narrative internally. Loose comments by managers such as “this is why we should not have hired them” or “they are just trying to cause problems” can become key evidence.

Why This Matters More Now

Retaliation claims continue to be one of the most common and most successful claims employees bring in California. They are also among the most expensive to defend.

The reason is simple. These cases are fact driven and often turn on credibility, which makes them difficult to resolve early and unpredictable at trial.

The Bottom Line

You can be right about the law and still lose the case.

The safer approach is to assume that any workplace complaint may be protected and to respond in a way that would hold up under scrutiny. That means slowing down, documenting carefully, and keeping decisions grounded in legitimate business reasons that can be clearly explained.

In California, the question is not just whether the employee was right, but also whether the employer acted right.
