> No manager PIPs someone for just being TOO good.
Eh, in my company, I've seen managers that will use tools to prevent people from leaving. Fortunately, they have tools other than PIP. But if they didn't, I'm sure they would wave the PIP wand.
One guy was senior and core to the team. When he wanted to move, his manager bluntly told him he needed him for another year so he would not let him leave.
One of the orgs in my company famously classifies all employees as "essential" (nothing to do with the pandemic). Because of that, any time someone wants to leave for another org, it has to be approved by the top staff of the org (this org has thousands of employees, BTW). Although they don't prevent everyone from leaving, they do often prevent people - to the point that during internal interviews some of them were dropped by the interviewing team as soon as they discovered the org they were currently with: "We've been burnt too many times going through the interview loop only to have your org block the transfer - we just won't hire from your org any more."
So yeah, I totally can believe someone would use PIP to keep a good performer in a team, if that's the only way they have.
