This guy is a peer. I have brought it up to the CEO and he really didn't want to hear about it because he likes the guy on a personal level. It leaves me more frustrated than anything.
Well, if he's a personal peer of the CEO, I'd tread lightly. How about send an gentle reminder email, then keep it to cover your ?
Peer, friend of the CEO or not.. The guy pays it back in a timely manner or deduct from his payroll.. If the CEO says to let it slide and to count it as a bonus... then 1099 him for it
