A report of mine constantly complains about everyone else in the team and adjacent team. The thing is the bar that this employee is so high that no one is probably going to close come to it. So today I told this person if you feel this strongly about all the folks in the team and want to change things, be their manager, to which the employee backed off and said oh no, I never want to manage them. I cant deal with them. And in my mind I was like, yeah then STFU because you cannot just sit there and keep complaining forever and when given an opportunity to actually do something about it, not want to do that either!
