Been at current job over a year, I work in a large office within a multi-disciplinary team of about 20 people. I just don't feel I fit in anywhere, there's multiple smaller groups but im often on my own. Even others who aren't part of the other groups seem to get along with everyone and have inside jokes, go get coffee etc. i just always feel on the outside. I haven't felt this way before in other jobs. It doesn't help that the team admin has taken a dislike to me (she dislikes many people and seems to think she rules the team). Every so often it bothers me, today they were decorating the office for Christmas and spent time putting things on each person's table, some people weren't even in the office yet my desk was skipped, it sounds silly but its just one more thing. Starting to think I should be looking for another job but then most other aspects of the job work well. AIBU?
