Background: Have been off work for four weeks due to depression and anxiety. Due to start back tomorrow on adapted hours (basically a couple of hours less than a full day to see how I do). Have full support of company director for this - she has been really understanding and has been brilliant throughout, and really supportive. My line manager is a different story.
There was a social with all in my department (about ten of us) this evening - I had been looking forward to it for a while. Nothing raucous, just a quiet dinner at a colleague's house as a kind of team bonding thing. I spoke to my line manager on Friday to tell her about the arrangements for this week as I'd sorted it with the director, and to make sure she was okay with it. Mentioned the team thing and she was really funny about it and said it would look really bad if I still went as I'd been signed off. She made me feel extremely uncomfortable and said I could come if I wanted but it was clear I wouldn't be welcome. She basically implied I was being unprofessional (she said more things too but I don't want to out myself).
My points for thinking she was BU are 1) I am back at work tomorrow anyway, 2) Staying in the house all the time makes me feel even more depressed and I'm supposed to be getting out when I can, 3) It's not like I wanted to go out clubbing, and 4) I am really nervous about going back and was looking forward to seeing the rest of the team beforehand so that would be one less thing to worry about.
Now I'm really worried about going back, because not only have I got to see them all for the first time again at work instead of in a relaxed environment, but now she clearly thinks I am unprofessional and made me feel an inch tall. I do wonder whether if I had had flu instead of a mental illness she would have had the same reaction.
