My department had a staff development day last year (think "fun" quizzes, group activities etc..) and I had a really bad time of it and it made me ill. I hate these type of things, am generally down about work anyway and some other personal factors contributed. We have another development day in a few weeks and I emailed the department manager to say that I really don't want to attend as I don't want to be ill/stressed again. Their response is that it's not optional and it's been arranged to align with my working pattern (I work part time) and that they have liaised with me to take on board my reservations and proposals (we did have a meeting after the event and she was quite good about asking me what they could do to accommodate me). It's making me well up just thinking about having to go but she mentions reasonable expectations and taking an active part. The tone of the email was quite curt and that's upset me now as well. I'm wondering if she's annoyed and thinks I can't be arsed to go. I know it might be different this time but I REALLY don't want to go. I'm worried now that if I don't go this will jeopardise my position here. am I obliged to attend even though it might make me ill again? Advise please?
