Can my employer fire me if I have been hurt while on-the-job?

Maybe. The answer may depend your state of residence, and it will always depend on the circumstances of the injury and the facts of your case. In some states, your employer may be mandated to reinstate you if your doctor releases you from treatment within a year and a half of the date you sustained your injury.

Consult with an injury lawyer who works with injured workers to find out how you may be affected.
