Genuinely poor performers are so toxic. They might not recognize their poor performance and suck up infinite amounts of support for no improvement. They might be ultra-aware of their game and manipulate the institution in mind-boggling ways to protect their graft. You have to get these folks out ASAP.

Of course, they could also be unrealized potential just waiting for someone to believe in them and mentor them to greatness. If you drop them too quickly you miss out on wonderful, loyal, capable people.

The trick is being able to tell the difference quickly, make the best choice you can, and move on.
