So how's our girl Leslie doing at your fine company? She's tossed herself around like a cork in a storm, and decided to pay you guys a visit for a year or two before moving on to the next unsuspecting place. Whatever you do, don't give her reports or the ability to reign over anything but her own accounts.
Clearly someone, or a team of people, didn't ask the internet or anyone at her former companies about her before bringing her on. There are not too many people who are universally disliked by colleagues, reports and superiors. But this lady happens to be one of them. If you're in her firing range, try to duck and cover until she moves on. Good luck in the meantime.
