Supervisors! Tell me how you did it.

About to be a 15. The 14’s below me have a history of poor performance with one being a real PITA. How do I go into this role setting myself up for success in dealing with them? I want them to be happy and successful- I also want them to be productive and held accountable. Should I try to outline this is their performance plans?

Please tell me the success and failures you’ve had when taking a new team. Even when everyone knows there is a bad apple being handed to you.
