Workers' Compensation After a Shoulder and Arm Injury

Attorney Answer

A shoulder or arm injury from work is covered without your having to prove anyone did anything wrong — and it is covered whether it happened in one moment or built up over months of the same movements. What the system asks of you is prompt reporting and consistent documentation. Shoulder claims are disputed on those two points far more often than on whether the injury is real.

Cal. Lab. Code § 3602(a) makes workers' compensation the exclusive remedy against your employer for a work injury, subject to narrow exceptions. That is the trade: you give up an ordinary lawsuit against your employer, and in exchange you do not have to show your employer was careless. For a shoulder or an arm, that matters, because the honest answer to "how did it happen" is often "lifting, reaching and repeating, for a long time" — which would be hard to blame on anyone and does not need to be.

What the claim provides is medical treatment for the injury, wage replacement while you cannot work, compensation if the injury leaves lasting limits on what your arm can do, and help returning to work. The amounts, the waiting periods and the way lasting impairment is measured are set by statute and are not stated here; they depend on your earnings and on the medical evidence. Expect the medical evidence to be the center of a shoulder claim.

One exception is worth checking early. If someone other than your employer caused the injury — another company's crew, a delivery driver, a defective tool or machine, or the owner of premises you were working on — a claim against that person or company sits outside the compensation system and can be pursued alongside the claim.

And if reporting the injury changes how you are treated at work, Cal. Lab. Code § 132a is the section to know: "It is the declared policy of this state that there should not be discrimination against workers who are injured in the course and scope of their employment." It provides for compensation increased by one-half up to $10,000, costs to $250, reinstatement and lost wages, and makes the conduct a misdemeanor.

What you can do

1. Report the injury to your employer in writing today — the written notice of injury under Cal. Lab. Code § 5400 — and ask in writing for a workers' compensation claim form, which Cal. Lab. Code § 5401(a) requires your employer to provide. Filing that form is what opens the claim; a verbal mention to a supervisor is not.

2. In that report, describe both parts if both apply — the single incident, and the repeated work that led up to it. Leaving out the repetitive part is how a real claim gets narrowed to one bad day.

3. Tell every provider you see that the injury is work-related, and ask for a written work status report at each visit. Give a copy to your employer the same day and keep one for yourself.

4. Follow the written restrictions you are given, and keep a copy of each set. Working outside your restrictions to keep the peace tends to hurt both the shoulder and the claim.

5. Keep a dated record of what you cannot do — reaching overhead, lifting, sleeping on that side, driving. In a shoulder claim, function over time is the evidence.

6. Note anything involved that did not belong to your employer, and raise it with an attorney; that is where a second claim would come from if there is one.

7. If the employer will not provide the claim form or the claim is denied, contact the state's Division of Workers' Compensation information and assistance service. It is free and independent of the insurer.

Most lawyers offer a brief initial call at no cost, and a few minutes on your specific facts is worth more than any general guidance, including this page.

⏱ Time limits apply. A workers' compensation claim carries deadlines fixed by statute, and for an injury that developed over time they can run from when you knew or should have known the problem was work-related rather than from any single day — which is exactly the kind of date people get wrong. If someone other than your employer was responsible, that separate claim runs on the two years given by Cal. Code Civ. Proc. § 335.1. This page will not compute either.
