How Long Do You Have to Report a Workplace Injury?

Were you hurt on the job in Wisconsin? There is a limited amount of time you have to report your injury. It is a legal requirement that you notify your employer about your injury if you want to get compensation from the workers’ compensation system. Understanding what to do can be confusing, but we are here to help.
At Plumtree & Brunner, LLP, our California workers’ compensation lawyers want you to get the compensation to which you are entitled. We take a personalized approach to your case and help you pursue every one of your rights.
California’s 30-Day Injury Reporting Rule
You must report your workplace injury to your employer within 30 days of when it happened. Technically, you are allowed to provide verbal notice, but written notice is always preferred. It will help you and your lawyer negate any argument that you didn’t notify your employer in time.
When the clock starts to run matters too. For most injuries, it begins on the day it happened. For others where the injury is not immediately apparent, you may have from when you discovered the injury.
Why Is It So Important to File My Claim on Time?
If you don’t file your claim within 30 days, it can result in a denial of workers’ compensation benefits. This gives your employer an excuse to deny your claim and claim the delay prevented them from investigating it.
Timely reporting helps:
- Preserve your eligibility for medical treatment
- Allow you to seek wage replacement
- Establish a clear record of the incident
- Prevent disputes over causation
- Prevent issues over timing
What Counts as “Notice” for my Workers’ Comp Claim?
California law doesn’t require a specific letter or legal document to count as notice. If you tell your supervisor, HR director, or other manager, this is likely sufficient. However, it is even better if you:
- Submit a written report
- Report your injury in an email
- Include the date, time, location, of the injury
- Include the nature of the injury
- Keep a copy for your records
Once you report it, employers have to file a Workers’ Compensation Claim Form (DWC-1). They must do this within one working day of learning about your injury. This starts the claims process.
Are There Exceptions for Cumulative or Latent Injuries?
Not all workplace injuries are sudden. California recognizes that some injuries develop over time. Others may not be immediately apparent. Here, the 30-day rule often applies from the date the employee knew or should have known the injury was work-related.
Examples of this can include:
- Repetitive stress injuries
- Tendonitis
- Back injuries
- Hearing loss
- Lung disease
- Post-traumatic stress from an accident
- Mental health issues from a work-related accident
If you’re unsure whether your condition qualifies, consult a workers’ compensation attorney or medical professional as soon as possible.
What If You Miss the Deadline?
Missing the 30-day reporting deadline doesn’t automatically bar your claim, but it creates significant hurdles. You may still be eligible for benefits if:
- Your employer had actual knowledge of the injury
- You were physically or mentally unable to report the injury
- The delay was due to fraud, misrepresentation, or other legal exceptions
Best Practices for Reporting Workplace Injuries
To protect your rights and streamline the claims process:
- Report the injury immediately, even if it seems minor
- Document the incident with photos, witness statements, and medical records
- Request and complete the DWC-1 claim form
- Follow up with your employer
- Keep copies of all communications
Prompt reporting preserves your legal rights It also ensures you receive timely medical care and wage replacement benefits.
