If you are injured at work, report it immediately. The sooner you inform management, the sooner they can start the process of you receiving the relevant compensation. Initially, you may verbally report the incident, but make sure you follow up in writing as soon as possible. Some states vary on what kind of notice is legally required, but remember, a paper trail is your friend. Also, remember that some states have a statute of limitations that requires you to file your claim within a certain time after the incident. Failing to do so may nullify some of your legal rights to compensation or benefits from your employer.
