I had surgery two years ago and ever since my arm has not been as strong. I find it painful to do repetitive work.
I spoke to my manager about this when I returned and said there would be a one job in the department I would be unable to do due to the repetitiveness of it.
So another member of staff has been doing this job but has now left and no one else in the department knows how to do it and my manager keeps pushing me to do it. I keep telling her I can't do it and that someone else needs to be trained but she's not listening.
