How California Workers' Comp Works: No-Fault & Exclusive Remedy

California workers' compensation (Labor Code § 3200 et seq.) is a no-fault system: covered employees get medical care and wage-loss benefits for work injuries regardless of fault. In exchange, workers' comp is the sole and exclusive remedy against the employer for a covered injury (Labor Code § 3602), with narrow exceptions. The system is overseen by the Division of Workers' Compensation (DWC).

California’s workers’ compensation system is built on Labor Code § 3200 et seq. and overseen by the Division of Workers’ Compensation (DWC). It rests on a tradeoff that shapes every case.

A no-fault system

Workers’ comp is no-fault. If you are a covered employee and you are hurt on the job, you get medical care and wage-loss benefits regardless of who was at fault — you don’t have to prove your employer did anything wrong.

The exclusive-remedy tradeoff

In exchange for those guaranteed benefits, workers’ comp is the sole and exclusive remedy against the employer for a covered injury (Labor Code § 3602). That’s the bargain: faster, no-fault benefits instead of a lawsuit where you’d have to prove fault and damages. The rule has narrow exceptions.

Who runs the system

The Division of Workers’ Compensation (DWC) administers California workers’ comp, including disputes that go before a workers’ compensation judge.

What this means for you

If you’re injured at work, your starting point is almost always the workers’ comp system — not a lawsuit against your employer. Learn the practical details in Coverage Requirements, Benefits, and Claim Deadlines. To get matched with a local California workers’-comp attorney, connect with a lawyer.

Failing to carry coverage is a crime and exposes the employer to penalties and direct liability.
