Not your circus, not your monkeys. What are your circus and monkeys is the fact that a job description includes...well, alas, working. A job is not about getting paid to shirk, or dally, or even fornicate, or whatever word you want to use in this situation. What you can do is send him an e-mail about something that depends upon his decision, and cc the bosses, so that he can see that they are in the know, and that you have no qualms about doing this. If he confronts you, tell him you tried calling him, and he will find your missed call(s) on his phone. A bcc would make him angry, and it's not worth it. Their perfume, their clothes, their eyewear, and their snogging is none of your business, I repeat. It's because you are stretched in all directions, and here are these two hamming it up, that you are so upset, not just because they don't pull their weight.
