I was injured working on the midnight shift. It happened right after break. I'm a sorter and was just lifting to an upper belt and felt something snap in my shoulder. My supervisor just happened to come by to ask me to sort 2 unloaders (something I've been doing for a while). I told him I was just injured and he asked if I was OK. I said, "I don't think so, I cant lift my left arm higher than a couple of inches." He said, " OK man, I'll let you go home first tonight" AN HOUR later he sent me home. He didn't report the injury to anyone and it being a Friday night, I naively figured I'd "tough" it out. I called in on Monday and let them know I wouldn't be in. They pretty much freaked out and the supervisor was fired but then rehired two days later. I have a note from my doctor saying I can't lift anything over ten pounds. It has been two weeks and I feel like I'm getting the runaround every night. They ask if I want to take the night off, or they'll say you can tape boxes. I tell them I can't lift anything over ten pounds and they try to make me feel bad about it. I have been trying to get approved to get an MRI, which my doctor ordered, and Liberty Mutual won't return any of my calls. I have a constant burning sensation in my entire arm and every time I try and use it there is a grinding followed by a pop and sharp pain. I guess I just need advice on what to do next. Should I contact the union, get a lawyer, just wait??? Any advice in dealing with this would be much appreciated.
