If you are injured on the job and later terminated by your employer you may have the right to file a claim under either state or federal employment laws that govern wrongful discharge and discrimination on the job.
Employment laws vary in different jurisdictions.
Therefore, if you feel that you were fired or discriminated against due to an injury sustained on the job, you should consult with an attorney who is experienced in workers' compensation and related laws. It is important to understand that there are specific deadlines for filing claims against your employer for wrongful discharge or discrimination.
