If your CRPS is WC related I thought they could not terminate you. However I understand laws very from state to state.
We battle this CRPS monster everyday and having to worry about things like jobs and insurance makes it even worse. Instead of using our energy to try to get better, or not to get worse, we are forced to use that precious energy on fighting to keep our jobs. I know we all wish we could go back to the way we were before CRPS. I would love to go back to work, being a nurse was more than just a job it was who I was. It is not right that you have worked hard to get and keep this job yet they can still terminate you.
Sorry to vent but as you can tell I have some strong feelings about this. I hope you can find a solution and can continue to get the help you need.
