It is against the law for an employer to fire an employee simply for filing a workers’ compensation claim. It is also illegal for an employer to retaliate against you in any other way for filing your claim, such as by threatening you, increasing surveillance of your activities on the job, giving you a negative job review, or giving negative job references. If you feel that this has happened, then you may have legal rights to sue for damages. Speak with a Philadelphia workers’ compensation attorney right away.
