If you are hurt at work, there are things you should expect from your employer. As long as the injury occurred during the performance of your job duties, and you followed company procedures and weren't intoxicated, you should be covered under the company's worker's compensation policy.
Worker's compensation provides that an employer pay your medical expenses if you are hurt at work. It also provides for payment at 2/3 of your average weekly wage if your injury has rendered you temporarily disabled. This compensation should cover you until you reach MMI or maximum medical improvement - ie. the doctor has released you from further treatment because there is nothing more they can do for you.
Once you reach maximum medical improvement, you will be given an impairment rating. This rating along with the part of the body that was injured will control how much your settlement can be. Each body part is worth a certain number of weeks of pay at your worker's compensation rate (2/3 of your average weekly wage).
Worker's compensation claims are subject to a statute of limitations. If your employer does not report the injury to the Worker's Compensation Commission, waiting can forever bar your claim.
