Usually you can’t sue your own employer for a work injury in California, because workers’ comp is generally your “exclusive remedy” against the employer. But you often have other options. You can sue a third party who caused the injury, such as a negligent driver or the maker of a defective machine, and you can sue your employer in a few narrow situations, such as when it had no workers’ comp insurance. Claims for wrongful termination, discrimination or retaliation tied to your injury are also generally separate from workers’ comp.
Key takeaways
- When an injury is covered by workers’ comp, comp is generally the sole and exclusive remedy against your employer (Labor Code §3602(a)).
- You can still sue third parties, meaning anyone other than your employer, for full damages including pain and suffering (Labor Code §3852).
- Lawsuits against an employer are allowed in narrow cases: no comp insurance, a willful physical assault by the employer, fraudulent concealment that worsened the injury, certain defective products the employer made, and removed power press guards.
- Being fired, harassed or denied accommodation because of your injury can support FEHA claims, separate from workers’ comp.
- Third-party lawsuits generally must be filed within two years, and claims against public entities require a written claim within six months.
Why you usually can’t sue your employer
Workers’ comp is a trade-off. You get medical care and disability benefits without proving anyone was at fault, and in return your employer is generally shielded from a negligence lawsuit. Labor Code §3602(a) makes comp the “sole and exclusive remedy” against your employer when the conditions for compensation in Labor Code §3600 are met. Even if your employer was careless, you generally can’t sue it for pain and suffering.
The same rule generally protects coworkers. Under Labor Code §3601, you can sue a coworker only if their willful and unprovoked physical act of aggression, or their intoxication, caused your injury. Our explainer on the exclusive remedy rule covers the statute in detail.
Your options outside workers’ comp
| Option | Who you may sue | Key law |
|---|---|---|
| Third-party personal injury claim | Anyone other than your employer whose negligence or defective product caused the injury | Labor Code §3852 |
| Uninsured employer | Your employer, if it failed to carry workers’ comp insurance | Labor Code §3706 |
| Willful physical assault | Your employer, for injury caused by its willful physical assault | Labor Code §3602(b)(1) |
| Fraudulent concealment | Your employer, if it concealed your injury and its connection to work, making it worse (recovery limited to the aggravation) | Labor Code §3602(b)(2) |
| Defective product made by employer | Your employer, for a product it made and sold to an independent third party who provided it to you | Labor Code §3602(b)(3) |
| Power press guard | Your employer, if it knowingly removed or failed to install a point-of-operation guard on a power press | Labor Code §4558 |
| Discrimination, harassment, retaliation, failure to accommodate | Your employer, under FEHA | Gov. Code §12940 |
If you recover civil damages from your employer under §3602(b) or §4558 after receiving comp, the employer gets a credit for the benefits it paid (Labor Code §3600(b)).
Third-party claims
Filing a comp claim doesn’t affect your right to sue anyone else who caused the injury (Labor Code §3852). Common examples:
- A driver who hit you while you were driving or making deliveries for work.
- The manufacturer of a defective machine, ladder, scaffold or safety device. See crushed by machinery at work.
- Another contractor on a multi-employer job site whose workers created the hazard.
- A property owner or business at a customer site with a dangerous condition.
A third-party case can seek damages comp doesn’t pay, such as pain and suffering and full lost earning capacity. Your employer or its insurer is generally reimbursed from the recovery for benefits it paid and may get a credit against future benefits (Labor Code §§3856, 3858). Claims against a property owner or general contractor that hired your employer face extra limits under California Supreme Court decisions. Our guide to third-party liability explains how the two cases fit together.
When your employer had no workers’ comp insurance
California employers must carry workers’ comp coverage or be approved to self-insure (Labor Code §3700). If your employer didn’t, Labor Code §3706 lets you sue it in civil court. You may also file a comp claim with the Workers’ Compensation Appeals Board, or do both (Labor Code §3715). If an illegally uninsured employer doesn’t pay a comp award, the state’s Uninsured Employers Benefit Trust Fund may pay it, though benefits aren’t automatic. See what to do if your employer doesn’t have workers’ comp insurance.
Firing, discrimination and retaliation claims
The exclusive remedy rule is about compensation for the injury itself. It doesn’t give employers free rein to punish injured workers.
- Labor Code §132a bars discrimination against you for filing a comp claim or being injured. That claim is filed with the Workers’ Compensation Appeals Board and can increase your compensation by one-half, up to $10,000, plus reinstatement and lost wages.
- The Fair Employment and Housing Act (FEHA) applies to employers with five or more employees. If your injury is a disability, your employer may have to provide reasonable accommodation and engage in a good-faith interactive process, and can’t fire you because of the disability (Gov. Code §12940).
- In 1998 the California Supreme Court held that §132a isn’t the exclusive remedy for disability discrimination, so FEHA and wrongful termination claims may proceed alongside workers’ comp, without double recovery.
FEHA claims start with a complaint to the California Civil Rights Department, generally within three years of the last harm. Read can I be fired while on workers’ comp.
Serious safety violations: more benefits, not a lawsuit
If your employer’s conduct was serious and willful, such as knowingly ignoring a dangerous condition, you generally still can’t sue. Instead, Labor Code §4553 increases your compensation by one-half, plus costs up to $250, when the injury was caused by the serious and willful misconduct of the employer or certain managers. That petition must generally be filed within 12 months of the injury (Labor Code §5407). See serious and willful misconduct.
A hypothetical example
Tomás, a warehouse worker, is injured when a forklift’s brakes fail. Comp pays his treatment and temporary disability, but he can’t sue his employer for negligence. An investigation shows the brake system was defectively designed by the manufacturer, so Tomás may bring a product liability lawsuit against the manufacturer for pain and suffering and full wage loss. When he returns with restrictions, his employer fires him rather than discussing light duty, which may support separate FEHA and §132a claims.
Deadlines to know
| Claim | General deadline |
|---|---|
| Workers’ comp claim | One year (Labor Code §5405) |
| Serious and willful misconduct petition | 12 months from the injury (Labor Code §5407) |
| §132a discrimination petition | One year from the discriminatory act or termination |
| Personal injury lawsuit against a private third party | Two years (Code of Civil Procedure §335.1) |
| Claim against a public entity | Six months (Government Code §911.2) |
| FEHA complaint with the Civil Rights Department | Three years from the last harm |
Frequently asked questions
Can I sue my employer for pain and suffering?
Generally no, if your injury is covered by workers’ comp. You may be able to if an exception applies, such as an uninsured employer or a willful physical assault by the employer.
Can I get workers’ comp and sue a third party at the same time?
Yes. You can generally pursue both. The employer is usually reimbursed for benefits it paid out of any third-party recovery.
My employer broke safety rules. Can I sue?
Usually not. Safety violations typically support a serious and willful misconduct petition for increased comp benefits rather than a lawsuit, unless a specific exception applies.
Can I sue if I was fired after my injury?
You may have claims under Labor Code §132a and, if your employer has five or more employees, under FEHA for disability discrimination or failure to accommodate. These are separate from your comp benefits.
Can I sue a coworker who hurt me?
Only in limited cases: a willful and unprovoked physical act of aggression, or an injury caused by the coworker’s intoxication.
