If injured and laid off with supervision knowledge of injuries and the need of surgery can pain and suffering and time loss from work

Was injured at work ,told supervision. Went to doctor had MRI was told needed surgery and the day before I was supposed to talk to surgeon I was laid off,and told would be hired back when work picked up,and a few weeks later I went by the company shop and they had already filled my position.I was told by a co-worker that supervisor told him he didnt hire me back because he was scared I would take time off,i thought that's what you did when you pay for accidentally insurance benefits and was injured and as a result need surgry.
