Well, I took your advice and worked it a bit to fit my personality. I took some things that I need him to update by next week, wrote the time I requested the work (which I shouldn't have to request) on the top of the paper with the due date and instructions on updating them (which he also shouldn't need) put them in his box. I then followed that all up with an email to him with all the same information and copied our boss. I used to coddle and babysit and often did most of the legwork for him, but now he's on his own.
Thank you for the advice, and thank you for asking. I'll let you know if it works. So far I have not heard a single word from him in two days.... no response, no good morning, no retaliation.... absolutely nothing. And if you knew him, you would know how hard it is for him to not talk.... so I take that as a good sign... I guess.
