What Is Workers' Compensation in California?

What is workers' compensation in California?

Workers' compensation is a type of required insurance. It covers medical care and replaces part of your lost income after a job injury or illness, no matter who caused it.

That is the short definition. California law requires almost every employer to carry this coverage, or to qualify as self-insured (Labor Code section 3700). When a worker gets hurt doing their job, the employer's insurance pays for treatment and a share of lost income while the worker recovers.

The trade-off is simple. A worker does not have to prove the employer did something wrong to collect benefits. In return, the worker generally gives up the right to sue the employer in court for that injury. The sections below cover who the law protects, what it pays for, and how a claim moves from a reported injury to paid benefits.

Who is covered by California workers' compensation?

Almost everyone who works for pay in California is covered, full time or part time, no matter their immigration status. Independent contractors generally are not, unless the work is really employment in disguise.

California defines "employee" broadly. Labor Code section 3351 covers every person hired under any kind of job agreement, spoken or written, "whether lawfully or unlawfully employed." That wording means immigration status does not decide coverage. Our guide on Labor Code section 3351 and immigration status explains this further.

The duty to carry insurance falls on the employer, not the worker. Under Labor Code section 3700, nearly every California employer must buy workers' compensation insurance or qualify to self-insure, even a business with just one employee. See our page on the Labor Code section 3700 insurance mandate for more on that duty.

A true independent contractor is not covered, since that person is not under an employer's control and direction. Plenty of workers get labeled "contractors" even when the work looks like a regular job. Under Labor Code section 2775, a worker is presumed to be an employee unless the hiring business proves otherwise through California's ABC test. If your status is unclear, see how the ABC test works.

How does workers' comp work in California?

A claim moves through four basic steps. You report the injury, your employer gives you a claim form, you get early medical care, and the insurance company decides whether to pay.

Step one is reporting the injury. Labor Code section 5400 gives an injured worker 30 days to tell the employer in writing, with narrow exceptions. Tell your supervisor as soon as you reasonably can. See the 30-day notice rule for what counts as proper notice.

Step two is the claim form. Once the employer knows about an injury that causes lost time or needs treatment beyond basic first aid, Labor Code section 5401 gives it one working day to hand over or mail a claim form, called the DWC-1. See how the DWC-1 claim form works. Filing that form with the employer starts the claim.

Step three is early medical care. While the insurance company decides whether to accept the claim, Labor Code section 5402 requires it to authorize up to $10,000 in treatment. The insurer then has 90 days from the date the claim form was filed to accept or deny the claim. Miss that deadline, and the law presumes the injury is covered.

Step four is the decision. An accepted claim means the insurer keeps paying for approved care and, if the worker loses income, wage-replacement benefits too. A denied claim can be disputed at the California Workers' Compensation Appeals Board (WCAB). Our guide to WCAB district offices explains how that process works.

What does workers' compensation pay for?

California workers' comp pays for medical care tied to the injury and part of the worker's lost wages. It does not pay a full paycheck, and it does not include pain-and-suffering money.

The exact weekly amount depends on the worker's earnings and, for permanent disability, a rating of how much the injury limits them. See how much workers' comp pays in California for the current weekly minimums and maximums, and whether these benefits are taxed.

What is the no-fault rule, and why can't I sue my employer instead?

California runs workers' comp as a no-fault system. A worker can collect benefits even if the accident was partly their own fault. In exchange, they generally cannot sue their employer in court for that injury.

Labor Code section 3600 makes an employer liable for workers' comp benefits "without regard to negligence," as long as the injury happened while the worker was doing their job. Neither side has to prove fault. A slip, a broken tool, or a sudden medical event at work can all lead to a valid claim, as long as the injury grew out of the job and happened during work.

That protection runs in the employer's favor too. Labor Code section 3600 says these benefits are owed "in lieu of any other liability whatsoever," and Labor Code section 3602 spells out what that means: once the conditions of compensation are met, workers' comp becomes the employee's exclusive remedy against the employer, except for a short list of situations the statute allows, such as a willful physical assault by the employer. A related rule, Labor Code section 3601, applies a similar bar to a lawsuit against a coworker who caused the injury while doing their own job, again subject to narrow exceptions. Our pages on the no-fault rule, the exclusive-remedy exceptions, and the coworker exclusive-remedy rule explain those exceptions in more depth.

What doesn't workers' compensation cover?

It does not cover injuries that happen off the job, pain-and-suffering money, or an injury caused by the worker's own intoxication or an intentional act of self-harm.

Workers' comp only applies to an injury tied to the job, so it does not pay for an injury or illness that has nothing to do with work. Labor Code section 3600 also excludes an injury caused by the worker's own intoxication or unlawful drug use, and it excludes a death the worker caused on purpose.

Workers' comp does not include the kind of money a lawsuit could award, such as pain and suffering or punitive damages. That is the flip side of the no-fault trade-off described above. Benefits are set by statute, not decided by a jury.

What should you do if a claim is denied, or you need help?

Read the denial letter for the stated reason, keep every document, and consider a free consultation with a workers' comp lawyer before a deadline passes.

A denial is not the end of a case. A worker can ask the insurance company to reconsider, or file for a hearing at the Workers' Compensation Appeals Board. Our guide on what to do after a denied claim walks through next steps and deadlines.

Many workers handle a simple, accepted claim on their own. A lawyer tends to help most when a claim is denied, a permanent disability rating is disputed, or a settlement offer is on the table. See whether you need a workers' comp lawyer for a closer look at that choice.

Knowing the basic rules is a good first step. Applying them to your own claim is harder, especially after a denial or a dispute over your medical care.
