I started my current (dream) job 4 months ago. Before this there was someone filling in the post on a temporary basis, she did this for over a year. She interviewed for my post against me but didn't get it. There is possibly another post coming up in the organisation in the next 1-2 years, which I assume she will apply for. She got on very well with the team, and since starting, I have made lots of effort to talk about the 'big shoes I have to fill' etc etc to get the team comfortable with me as a leader.
Tonight we had our team Christmas night out, and she was there. She was clearly invited, but I was surprised to see her. AIBU to think that you don't come to the work night out of a team which you are no longer part of? I feel that tonight was an opportunity for me to build relationships with my new team and it was all a bit weird her being there. I get that this is all about my own insecurities in my new job. But still feel that it's not unreasonable to want her to leave me to settle into my new role in peace!!!
