I was injured 11/24/09 at work unloading trees off a semi, it tore my shoulder. I had an mri and it showed three small tears so they sent me to an orthopaedic surgeon. He said he thought they would heal with p/t, so I did therapy for two months with no improvement so he wanted to do surgery to clean up the scar tissue. He did surgery on 2/2/10 it was worse than the mri showed he removed bone spurs, part of my collar bone, and found two more large tears he repaired and reattached the tendons. He wanted me off work until 6/9/10. I went in for my check up today and he told me workmans comp wrote him and said I have to go back to work Monday on light duty. He said I can not use my left arm for anything at all, not even to make change. Well I am a cashier, I have to use both hands and arms, oh and no lifting . There is no job at my work which is a grocery store that you can do with one arm.My DR says if my boss says there is no light duty that I can do with only one arm then w/c will let it go I do not think they will, he also said to go ahead and go back but if they tell me to do something and it requires using my arm to walk out and call him and he will fight them. My question is can the insurance company make me go back to work before the doctor thinks I am ready to go back, it has only been 8 weeks since my surgery and if I do walk out can they drop my comp case or can they fire me for leaving my job ?
