I'm a dick

So one of my employees is a token employee. He only has a job here cause he's related to my manager, but even she can't stand him. He's super slow and just plots around. He will do what he's told, in between smoke breaks, but it just takes forever for him to get it done. Well sure enough he comes to me and says he is giving me his 2 weeks notice. Oh really??? Yeah, somehow I have a feeling I will be excepting his resignation effective tomorrow. I'm such a dick, but I'm done with this charity project.
