i am a 38 yr. old male in illinois, in an upper management pos. we were short handed one day at work so I though I would lend a hand. low and behold (make a long story short) while lifting material i tore a disk in my back. L5-S1. I had surgery and therapy and reached my MMI. i am ok'd to go back to work , and was told that they hired someone in my position. I have minimal restrictions but no job and no money. Do i have any rights in this matter and can I file a claim with the ADA. PLEASE HELP
