I’m there to work and earn money, not to make friends, not to fake a friendship with any manager.

That seems sad to me.

I managed a team for a few years. Another team in our organization made a pitch to take two of the people from my team into theirs. I ended up going along with the plan because it was a way to quickly get them a salary increase that I’d been trying to get for them for years. The rest of my team got absorbed into another team in our group and I transitioned to a non-management role.

We still chat constantly and we get together regularly for dinner. I consider them all close friends.
