How Do I File a Cal/OSHA Complaint in California?

How do I file a Cal/OSHA complaint in California?

Call or email the Cal/OSHA Enforcement District Office nearest your worksite. There is no separate online Cal/OSHA complaint form, even though many workers search for one by that name.

California's Occupational Safety and Health Act of 1973 gives every employee the right to report an unsafe or unhealthy workplace condition to Cal/OSHA. You do not need a lawyer, a case number, or proof that the hazard already hurt someone. You only need to reach the office that covers your worksite. Call between 8 a.m. and 5 p.m. Monday through Friday. Or email the district office that the Cal/OSHA Enforcement Office Search finds for your worksite zip code.

This is a safety complaint, not a wage claim. If your issue is unpaid wages, meal breaks, or overtime, that goes to the Labor Commissioner's Office instead of Cal/OSHA.

What information should I include in a hazard report to Cal/OSHA?

Describe the hazard, the worksite, and your employer in enough detail for an inspector to find and evaluate the problem.

Cal/OSHA does not expect you to know which safety order applies before you call. Its own complaint page says it is not necessary to know the exact standard a hazard may violate. What helps most is a clear, specific description of what you have seen.

You do not need every detail in hand before you call. Tell district office staff what you noticed, where it is, and how often it happens. Staff can ask follow-up questions for anything else they need.

Do I have to give my name, or can I file anonymously?

You do not have to give your name. If you do, Cal/OSHA must keep it confidential by law unless you say otherwise.

If you give your name, phone number, or address, Cal/OSHA keeps that information confidential during the investigation. The exception is if you say it is fine to share it. If you leave your contact information out, Cal/OSHA still accepts and looks into the complaint. Cal/OSHA just sorts it differently. An employee or representative who gives contact information gets a "formal complaint." One filed without that information becomes a "non-formal complaint." The label changes how Cal/OSHA tracks the complaint and whether it can send you a result afterward. It does not mean a non-formal complaint gets ignored.

What happens after I file: an inspection or a letter?

Cal/OSHA opens a surprise onsite inspection for serious or imminent hazards. For less urgent ones, it sends your employer a letter and gives it 14 days to answer in writing.

Cal/OSHA decides which path fits based on what your complaint describes. A hazard that threatens real physical harm, or looks like an imminent danger, generally gets a surprise onsite inspection. A less urgent hazard generally gets a letter instead. Cal/OSHA sends your employer a description of what you reported. The employer must respond in writing within 14 days. That response has to explain what the employer found and what it fixed or plans to fix.

If you gave contact information, Cal/OSHA sends you a copy of your employer's written response. You can then ask for an onsite inspection if that response does not satisfy you. When an onsite inspection happens, you or your representative can go along with the inspector. You can also speak with the inspector in private. The inspector will interview other employees in private too. Afterward, Cal/OSHA sends the worker or representative who filed the complaint a letter describing what it found. That letter includes copies of any citations. Your employer then has to post those citations, or the investigation letter, near the hazard so other workers see them too.

Can my employer punish me for contacting Cal/OSHA?

No. California law and Cal/OSHA's process both bar an employer from firing, demoting, or otherwise punishing you for reporting a safety or health hazard.

California Labor Code section 6310 makes it unlawful for an employer to discharge or discriminate against an employee for a safety complaint to Cal/OSHA, another agency, the employer, or a representative. Cal/OSHA's own complaint page lists what that can look like. Examples include firing, demotion, a transfer, or a layoff. Other examples are losing a shot at overtime or a promotion, an unwanted shift change, or losing a benefit such as sick leave or vacation time. The California Labor Commissioner's Office investigates these retaliation complaints. That is a separate track from Cal/OSHA's hazard investigation. Cal/OSHA's complaint page lists 833-526-4636 as the Labor Commissioner's general line for that concern. Our guide to Labor Code 6310 retaliation protection covers that complaint process in full, including the filing deadline and what to save as proof.

Behind the complaint sits a basic duty. Labor Code section 6400 requires every California employer to provide a workplace that is safe and healthful. If the hazard you reported already caused an injury, that duty can matter in a workers' compensation claim. So can any citation Cal/OSHA issues because of your complaint. Our guide to Labor Code 6400 and your comp claim explains how. A known, uncorrected hazard can also support a serious and willful misconduct claim for an added amount. That added amount applies when the employer knew about the danger and failed to correct the hazard.

When does a lawyer help with a safety complaint or the injury behind it?

A workers' compensation lawyer will not file your Cal/OSHA complaint for you, but can help once the hazard already caused an injury or your employer retaliated against you.

Filing the complaint itself takes no lawyer. Call or email the district office and describe what you saw. Where a lawyer tends to matter is what comes next. If the hazard already hurt you, the injury starts its own workers' compensation claim, with its own deadlines and medical care rules. Our overview of the California workers' comp claim process explains how that works. If you believe your employer punished you for speaking up, that is a separate legal problem from the injury claim. Both the timing and the paper trail matter there. If a lawyer takes your case, the fee usually runs 15% to 18%. A workers' comp judge must approve that fee before it is paid (Labor Code section 4906).

Yazdchi Law P.C. represents injured workers across California from its Palmdale office. Maybe the hazard you reported to Cal/OSHA already caused an injury. Maybe your employer retaliated against you for speaking up. Either way, the firm can review what happened. Call (661) 273-1780 or use the contact form. The firm reviews each matter individually and does not take every case.
