I work for a large, international company. It has strong HR policies about bullying, harassment etc.
Over the last two years my manager has quietly and subtly sidelined me through not giving me high profile project to work on (I have evidence that the work has not been fairly distributed), putting people who are junior to me in charge over me on projects, asking for my opinion in team meetings but then rejecting any of my suggestions, done deliberately in front of team to undermine me. I now very rarely speak up in meetings, in my annual review was told that as the most senior member of the team I should be contributing more and teaching younger staff.
I have been keeping notes for the last couple of years, including screenshots of team messages where she has been rude and dismissive of me. Writing this down, it doesn't sound like much but I am being deliberately vague on details - there is more and it's worse than this sounds but also possibly outing or recognisable.
Members of our team have joked about being depressed and wanting to leave. Bear in mind this is a household name and to get a job here is a huge achievement.
I have been raising concerns about her for 18 months and I have recently found out that people in other teams have also been raising concerns. So, next week, I have a meeting with her senior. I need to explain in a non-emotional way what has been happening and that they need to move me to another manager. My job within the company is fairly niche and I don't know how this can be done but I really can't afford to lose this job - I'm the breadwinner.
I think she is making it unbearable for me so that I leave, but not bad enough for me to raise a grievance. She often gets me to do presentations to senior staff so it looks as if I am being treated fairly. But she won't let me work on any projects where I would have to talk to them or develop a relationship with them, which she allows junior staff to do.
Is there anything I should bear in mind about what to say/not say? I have lots of evidence of not being treated fairly and where other team members are given leeways that I am not. I'm just really, really scared of going up against her, I have seen how she operates when someone is her 'enemy' and it is ruthless.
Part of me thinks I should just suck it up but I've been in counselling for the last year and feel genuine dread at the thought of seeing her every day.
