Labor Code 3550 Employer Notice Required

The rule requires a clear posted notice with insurance, claim, treatment, benefit, deadline, and contact information for employees.

What the Poster Must Do

The workplace notice is meant to be seen before an injury happens. It cannot be hidden in a file or placed where workers do not go. Employees must be able to read it during regular work hours.

The notice must identify the current workers' compensation insurance carrier. If the employer is self-insured, the notice must say that. It must also identify who handles claim adjustment.

The notice must be understandable. If Spanish-speaking employees work there, it must be posted in English and Spanish. A notice that workers cannot read does not give useful help after an injury.

Information the Notice Must Include

The notice must explain how to get emergency medical care after a job injury. It must describe the types of injuries and illnesses covered by workers' compensation. It must also explain the right to medical care.

The notice must discuss treating doctor rights, benefit types, reporting instructions, and time limits. It must include information about temporary disability, permanent disability, supplemental job displacement benefits, and death benefits when those benefits apply.

The notice must also tell workers that they may consult a licensed attorney about workers' compensation rights. In most cases, attorney fees are paid from the injured worker's recovery, not as hourly bills paid up front.

Why a Missing Notice Matters

A missing notice can affect more than paperwork. The statute says failure to keep the notice posted is a misdemeanor and initial evidence of noninsurance.

The failure can also affect medical control. If the employer does not provide the required notice, the worker may be allowed to treat with a personal physician for an injury that happens during the failure.

These issues do not prove every part of the claim. They can still matter when there is a fight about reporting, treatment choice, insurance status, or what information the employer gave the worker.

Examples of Posting Problems

Posting problems often look simple. The poster may name an old carrier. It may be covered by other papers. It may be placed in an office employees cannot enter. It may be English only even though Spanish-speaking crews work there.

These facts can matter after an injury. A worker may not know where to report the claim. A supervisor may send the worker to the wrong clinic. The insurer may later argue that the worker waited too long or did not follow the right process.

Photos are useful. A photo can show the break room, time clock, shop wall, dispatch area, or other place where the poster should have been visible. Dates and witness names help too.

When to Raise the Issue

Raise the posting issue when it connects to a real dispute. It may matter if treatment was delayed, the carrier name was unclear, or the worker did not know where to report the injury.

It can also matter when an employer says the worker ignored rules that were never posted in a useful place.

What to Save

Save photos of the place where notices are posted. Save hiring papers, handbooks, and any paper that names the insurance carrier.

If the workplace has Spanish-speaking employees, note whether the notice was posted in Spanish. If a supervisor told you where to report an injury, save that message too.

Firm Review of Posting Issues

Yazdchi Law reviews posting issues by looking for photos, handbook pages, onboarding papers, carrier names, Spanish-language posting, and messages about where injuries should be reported.

Those facts can help answer carrier arguments about late notice, wrong clinic use, or confusion about claim handling. They can also show whether the employer kept workers' compensation coverage information current.
