A work injury can turn an ordinary shift into weeks of pain, paperwork, and worry about your job. What to do after a work-related injury in California comes down to two steps on two different clocks. Under Section 5400 of the California Labor Code, you have 30 days to give your employer written notice of the injury. Once your employer knows, Section 5401 of the California Labor Code gives it one working day to hand you the Division of Workers’ Compensation (DWC) claim form known as the DWC-1, which you then fill out and return.
The second step is easy to miss, because it depends on paperwork your employer controls.
What Should I Do First After a Work-Related Injury?
A handful of steps in the first few days carry the most weight:
- Get medical care and say the injury happened at work: Your employer must provide treatment reasonably required to cure or relieve a work injury, and telling the provider up front keeps the record clear.
- Sort out which doctor treats you: A personal doctor who has treated you before, and whom you named in writing before the injury while you had non-work health coverage, can treat you from the start. Otherwise, you can generally switch to a nearby doctor of your choice 30 days after reporting the injury, unless your employer or its insurance carrier uses a medical provider network (MPN), a contracted group of doctors with its own rules.
- Put your notice in writing: The notice should be signed by you or someone acting for you, and a dated copy is worth keeping.
- Ask for the claim form if it does not arrive: Your employer’s duty to provide it applies once the injury causes lost time beyond your shift or needs more than first aid. A written request, with a copy kept, creates a record if the form never comes.
Missing the 30-Day Notice Deadline Does Not Always End a Claim
Under Section 5402 of the California Labor Code, if your employer learned about the injury from any source, such as a supervisor who saw it happen, that knowledge counts the same as written notice. That safety net has limits, though. An employer may later dispute what it knew and when, and a signed, dated notice takes that argument off the table.
Reporting the Injury and Filing a Claim Are Two Different Steps
Each step in a claim runs on its own timeline:
| Step | Who acts | The clock |
| Written notice of the injury | You | 30 days from the injury |
| DWC-1 claim form and notice of potential eligibility | Your employer | 1 working day from notice or knowledge |
| Filing the completed claim form | You | No fixed date, but filing pauses the one-year clock |
| Starting proceedings for benefits | You | 1 year |
The completed form goes back to your employer, not to a court. It counts as filed when you hand it over or when it arrives by first-class or certified mail, and your employer owes you a dated copy. That handoff is the formal start of the workers’ compensation process in California.
The one-year limit comes from Section 5405 of the California Labor Code, and filing the claim form pauses it until your employer denies the claim or the injury becomes presumptively compensable, meaning the law treats it as covered. That clock does not always start on the injury date. It can also run from the end of a disability payment period or from the last date medical treatment was provided.
Where a Kern County Workers’ Compensation Case Gets Filed
When your employer or its insurance carrier disputes a claim, the next step is usually an application for adjudication of claim, the form that opens a case with the Workers’ Compensation Appeals Board (WCAB). California lets you file it in any of these counties:
- The county where you live on the filing date
- The county where the injury happened
- The county where your attorney’s main office is, if you have one
For most Bakersfield-area workers, those choices point to the WCAB’s Bakersfield district office. The DWC’s guide to filing an application for adjudication of claim lists the papers that must go with it.
What Happens After You Turn In the DWC-1 Claim Form?
Within one working day after you file the claim form, your employer must authorize medical treatment for the claimed injury and keep providing it until the claim is accepted or rejected. Three rules govern that stretch:
- Coverage is capped during review: State law limits how much treatment your employer must pay for while the claim is pending.
- Authorized care is not an accepted claim: Treatment provided during the investigation does not mean your employer has admitted liability.
- 90 days is the outer limit: If your employer does not reject the claim within 90 days of filing, the injury is presumed compensable, and that presumption can generally be overcome only with evidence that could not reasonably have been found sooner.
A rejection inside that window is often where questions about a denied workers’ compensation claim begin.
Are All California Workers Covered by Workers’ Compensation?
Not every worker is. California workers’ compensation covers employees whose injuries arise out of and in the course of employment, a two-part test often shortened to AOE/COE. It means the work caused the injury and you were on the job when it happened. When the conditions are met, the employer is liable regardless of who was at fault.
Genuine independent contractors generally fall outside the system. Rideshare and delivery drivers who work through apps such as Uber, Lyft, and DoorDash are exempt from workers’ compensation coverage in California. Under Section 7451 of the California Business and Professions Code, approved by voters as Proposition 22, these drivers are classified as independent contractors rather than employees.
Firing or Punishing You for Filing a Claim Is Against California Law
It is natural to worry that reporting an injury could cost you your job. Under Section 132a of the California Labor Code, it is a misdemeanor for an employer to fire you, threaten to fire you, or otherwise discriminate against you because you filed a workers’ compensation claim or said you planned to. A misdemeanor is a criminal offense, separate from anything that happens in your claim.
A firing like that is a form of wrongful termination, and the worker may be entitled to reinstatement, meaning getting the job back, along with other remedies. The protection also applies while a claim is open, so being fired while receiving workers’ compensation comes down to the employer’s real reason.
