I manage people at a pretty large corporation. Never take anything personally. I have had a few bad apples and the best thing to do is document everything, give them feedback of what they're doing right and wrong and how to improve, and to give them warning. We like to put them on a plan of how to improve and if they do not improve, then they get fired with no surprises.


and tell them they should know better than to slack off. If you treat them with respect then they'll do the same. And make sure you inspect their work even if it's a veteran. They can have their lazy days too.
