Backstory:
One of the managers in my office (but not my direct line manager) was very hot and cold with me. I respected her, but she would be very difficult at times. I have literally seen her swear and be discriminatory to do that - lots of complaints. She sort of did her best to exclude me from development opportunities, kicked me out of group chats, would always be in my manager’s ear about petty things about me. Other times she was nice.
The promotion:
I applied for and was successful in a promotion 2 steps above my previous role. I started this job in summer. Eg 2 grade jump in NHS or civil service. So I am now more senior than my old management. Also this manager in question was on temporary promotion, and is now back in her substantive job which was the job I left!
The situation:
This manager applied for a job and I am supposed to be chairing the interview panel. I feel this is unfair because I don’t feel comfortable. I think my presence will throw her off as it’s a proper full circle moment. AIBU? As my manager said it’s unavoidable to interview someone you used to work with and said I can just be professional.
