And of course a team doesnt fail because they hired a toxic person — if at all the fail because they dont fire them.

If a person harasses, steals or engages in other criminal behaviour you fire them. if they dont do their job, you fire them. if they just have different opinions, you suck it up and you value them. But hey, you cant: they werent licakbale enough in that short time you looked at them — so: NEXT!
