> point out how they’re holding back the team to the other people on the team (ie talk shit)

It is terrifying to think that you are in any kind of leadership position. I instantly lose respect for anyone who "talks shit" about team members, especially leaders. If I found out anyone was talking shit, especially someone in a leadership position in my company I would fire them on the spot. Well, I would first ask to speak privately so that they could still have the dignity they were denying their former team.

There are no bad teams, there are only bad leaders.
