California Labor Code 132a: Claims, Deadlines, and Remedies

California Labor Code Section 132a makes it illegal for an employer to fire, demote, cut hours, threaten, or otherwise punish a worker for getting hurt on the job, filing a workers’ compensation claim, or testifying in a coworker’s claim. An employee who has been retaliated against can file a petition with the Workers’ Compensation Appeals Board within one year and seek reinstatement, back pay, and increased compensation of up to $10,000.¹

What Counts as Retaliation

The statute reaches four types of conduct. An employer cannot fire, threaten to fire, or take any negative action against an employee because that employee filed a workers’ compensation claim, said they were going to file, or received a rating, award, or settlement. The same protection covers employees who testify or plan to testify in a coworker’s case before the Appeals Board. On the insurer side, a workers’ compensation insurer cannot pressure an employer to discharge or discriminate against a worker by threatening policy cancellation, higher premiums, or any other consequence.¹

“Discrimination” is read broadly. Termination is the obvious case, but the statute also reaches cutting hours, passing someone over for a promotion, demoting them, reducing pay, or refusing to rehire after a medical release. A threat to do any of those things is itself a violation. The question is whether the injured worker was singled out for worse treatment than other employees would have received in the same situation.

What You Have to Prove

A worker filing a 132a petition has to show three basic things to the Appeals Board: a work-related injury, employer knowledge of the injury or claim, and some adverse action taken afterward.¹

That is not enough on its own. In Department of Rehabilitation v. Workers’ Compensation Appeals Board (2003) 30 Cal.4th 1281, the California Supreme Court added that the worker must also show they were treated differently than uninjured employees would have been. The employee in that case objected to using sick leave for injury-related medical appointments, but the court found no violation because every employee had to use sick leave for medical appointments, injury or not.²

This is where most 132a cases turn. You need a concrete comparison: uninjured employees who missed similar amounts of work kept their jobs, or a promotion went to someone less qualified once your claim was on file. Without that comparison, the petition tends to fail.

Once the worker makes that initial showing, the burden shifts to the employer to give a legitimate, non-discriminatory reason for the action. If the employer produces one, the worker gets a chance to show the stated reason is a pretext.

What the Employer Can Argue Back

The main employer defense is business necessity. Under Smith v. Workers’ Comp. Appeals Board (1984), any adverse action tied to an industrial injury is presumed discriminatory unless the employer proves the action was required by the real needs of running the business.²

That standard is not a low one. A genuine company-wide layoff that eliminated the position, or proof that the worker cannot perform the essential functions of the job even with accommodations, can qualify. The cost or inconvenience of the injury itself does not. The employer has to show it would have taken the same action even if the worker had never been hurt.

What You Can Recover

When the Appeals Board finds a violation, three categories of relief are available:

Reinstatement to the job, plus reimbursement for lost wages and work benefits from the date of the discriminatory act through reinstatement.
An increase in workers’ compensation benefits of one-half, capped at $10,000. This is a penalty on top of the underlying comp benefits.
Costs and expenses of the proceeding, capped at $250.¹

The $250 cost cap has not been adjusted since the statute was written, so workers pursuing a 132a petition absorb most of their own litigation expenses in practice.

Deadline and Where to File

A 132a claim is filed as a petition with the Workers’ Compensation Appeals Board, usually inside the worker’s existing comp case. The statute of limitations is one year from the discriminatory act. If the adverse action was a firing, the clock starts on the termination date. Miss the deadline and the right to file is gone, no matter how strong the underlying facts are.¹

One trap: the year runs from the act itself, not from the day you figured out it was retaliation. If a promotion passed you over six months ago and you only now connect it to your comp claim, six months is what you have left.

132a and a Separate FEHA Lawsuit

The same firing or demotion can support both a 132a petition and a civil lawsuit under California’s Fair Employment and Housing Act, which prohibits disability discrimination.³ The California Supreme Court confirmed this in City of Moorpark v. Superior Court (1998) 18 Cal.4th 1143, holding that Section 132a is not the exclusive remedy and that FEHA claims and common law wrongful discharge claims can proceed alongside a 132a petition.⁴

This matters because FEHA reaches things 132a does not. FEHA cases go to civil court, where damages for emotional distress are available. FEHA also imposes an affirmative duty on employers to provide reasonable accommodations for disabilities, which 132a does not. The tradeoff is that FEHA litigation costs more and takes longer than a petition before the Appeals Board. Where the two claims overlap, courts apply equitable principles to prevent double recovery, so back pay collected through a 132a settlement cannot be collected a second time in a FEHA suit.⁴

Criminal Penalties

Every violation of Section 132a is also a misdemeanor, applying to both retaliating employers and pressuring insurers. The Appeals Board itself cannot try criminal charges. It can refer suspected violations to the Division of Labor Standards Enforcement, and a worker can file a complaint directly with the Division or the local prosecutor.¹ Criminal prosecution under 132a is uncommon in practice. The civil petition before the Appeals Board is the route almost every injured worker takes.
