If you are hurt at work in Illinois, take care of yourself first, then protect your claim with clear, written records. This guide is general information only — see the Disclaimer. If you are seriously hurt, get emergency care first.
En español: Qué hacer después de una lesión en el trabajo en Illinois
1. Get medical help
Get care right away, even if the injury seems small. Tell the doctor it happened at work, describe how it happened, and mention every body part that hurts. Keep copies of discharge papers, work restrictions, and follow-up instructions.
2. Tell your employer — in writing
Report the injury to your employer as soon as possible, and in writing. Illinois generally requires notice within 45 days, but do not wait — a late report can be used to deny a claim. See How to report to your employer in writing for a sample wording and what to keep.
3. Write down what happened
- Date, time, and place of the injury, and what you were doing.
- Names of witnesses and anyone you told.
- Photos of the scene or equipment, if safe to take them.
- Every symptom, even if it starts later.
4. Keep every document
Keep medical bills, prescriptions, mileage to appointments, time missed from work, and any letters from your employer or insurer. Do not sign a statement, a settlement, or a release without understanding it — and consider talking with a lawyer first if you are unsure. See MMI, settlement vs. award.
5. Follow your doctor and ask about treatment
Follow treatment and restrictions, and ask about physical therapy if your doctor recommends it. See Illinois workers’ comp physical therapy and Choosing your own doctor and the two-doctor rule. If treatment is denied or stopped, see Claim denied.
Forms you may be asked to sign
After an injury, the insurer may send forms for you to sign. The most common is a medical release — permission for the insurer to get your medical records. You do not have to sign every form on the spot, and you can ask for time to read it and get advice.
There is a difference between a release for records related to the injury and a blanket release for all of your medical history. A release limited to the injury and the care for it is usually what the insurer needs. A blanket release may let the insurer look at records that have nothing to do with the claim. Read what the form says, and ask what it covers, before you sign it.
If you are unsure about a form, get advice before you sign it. Read Do I have to give a recorded statement to the insurance company? and Choose Your Doctor and the Two-Doctor Rule. Speak with a lawyer if a form asks for more than you are comfortable giving.
