So recently, I just went combo and I'm basically doing two hard jobs back to back. Their are other people who went combo and they were about to stay in their original area for twilight and went somewhere else for midnight or just stayed in their original area for both shifts. I found out, that is not what they are supposed to do and need to go to the jobs they bidded on. I asked to go back to my original area just for twilight and I was told there was nothing that can be done and that management is working on making sure people are in their supposed areas. My thing is, that's bs for the fact that management would have to spend a lot of time trying to figure all that out and they are not going to do that. I explained to my hub manager about the tendinitis in my wrist and that if I were to wear a brace on my new position during twilight, it's going to be extremely difficult for me compared to when I was in my original area where I won't have any problems. My question is, should I just build a case on it or just disqualify myself and go back to part time?
