Long story short - I work in a small team at a senior level. One of my colleagues (same level) has been passively aggressively targeting me for the last year but it’s escalating - they’ve made no secret that they want my job and have asked our boss to move them into my role (I would be swapped into another position).
They persistently call attention to mine and my team’s workload/actions in a negative way in meetings in front of others (incl our boss). I had to work jointly with them recently and one of my team made a mistake - we had a meeting with my boss and I apologised, took it on the chin and put in place a recovery plan. The colleague proceeded to email me multiple times with junior colleagues copied in criticising my team (and by association, me). Then raised it on a call with people who had no involvement and when I said let’s take this offline, point blank refused and proceeded to berate me. My boss said NOTHING.
I emailed her telling her I’d had enough and this was far from the first incident I’ve raised with her. Previous examples include my staffing decisions being criticised - literally nothing to do with them! My boss called me and told me that I should think very carefully about making things formal and basically that she wouldn’t support me.
What do I do now? I’m waiting on union advice but I’m already confident if I make it formal they will brush it under the carpet. This colleague has a history of bullying claims being made against them but all have been brushed off.
I work in the public sector and we don’t have a HR department to support on things like this - it’s all dealt with locally.
AIBU to make things formal?
