I joined my current company a year and a half ago and I've had the same manager since then. My manager has been stressing out in our one-to-one meetings that I am not performing adequately, even though both my team colleagues and colleagues I've worked from other teams, both in our location and other locations within the company have been pointing to me, in person and via emails, that my work is outstanding. I reached the conclusion that the personal relationship with my manager is influencing my manager's view of my work. The one-to-one meetings have become increasingly stressful and I concluded this is not going to improve.
I recently approached the leader of another team in the same department to see if I could transfer to this other team (i.e, team B). Team B recently had a member departing of the same grade as me in team A, and I had a meeting with the team's B leader to ask him if he would take me in his team. The first thing he said is that he recognized my name was mentioned in all "high impact" projects in the department, which he appreciated. He asked me if I had mentioned this idea of moving laterally to my current line manager and I said I didn't. Still haven't. I said I would like him to think about the idea, and he said he was positive and would think about it.
It could be that both line managers have talked about this, but haven't mentioned anything to me. I would like to know what is the best way to approach my current line manager about the idea of me moving to team B.
Should I mention it in our next one-to-one meeting? Should I ask for a meeting between the three of us? What should I say?
