I manage a team of product managers. We have a promotion period once a year. The process is like this: the manager nominates some of their team members, then a group of seniors and directors would assess the case.
We tend to have one product manager ready to be promoted (or at least close) every year. However, this year I don't have any qualified ones.
My manager wants me to promote one of my product managers, but I disagree on that. That person, in my opinion, is not yet ready.
My manager keeps pushing, he is saying that the person has potential and ultimately would be good in the new role. My point is that let's wait until next year, because a senior product manager can create more damage than good.
I discussed this many times with my manager, and he started using my performance as a way to play the game. He is saying that my role as a manager is to make sure people are ready and to grow them, which I find very weird because during the years I've promoted 4 already.
How should I go about handling this situation?
