I have an old back injury that has taken me out of work. I was able to take a week of PTO to try and recover but its gotten no better. I've seen many doctors and have another appointment with pain management soon. However, standing, sitting walking is extremely painful. I have to go back this week, I can't quit, I'm the only income for my household. Disability is seems impossible to obtain, workers comp isn't possible because the injury happened years ago. I don't know what options I have, I kinda think my only choice is to get fired so I can collect the extremely low unemployment until I can maybe get Disability to take. I might not be seeing the right exit strategy. Anyone have ideas?
