I can concur with this. I actually have responsibility for two teams at present in a way - one team I can fire all of and the other that even people three levels above me cannot it appears because of contractual relationships that are stronger than anything else. Even though someone had one of my team members fired, he couldn't fire everyone because both of the teams I have some responsibility for are different contracting companies. The team that I can't fire is the team that I consider a net negative amount of work performed because I or another person I delegate has to do their work for them repeatedly. They have shown no capacity to learn (we have to write runbooks for them still to the detail that we should just write a shell script with the time spent, so now we have unreliable humans that are executing bash scripts).
