edit wrong thread
Why don't you tweet him saying "are you actually going to do some work you lazy """ mother """""""". or you could forward the twitter link to your boss saying "just so you know what he's doing during work hours".

In fact - He keeps sweets on his desk, so should I probably just rub them in my nut sack and replace them in the packaging?
We've got someone like that where i work.
Last time i spoke to him i got a verbal warning from my boss on the grounds of bullying. I now refuse to talk to him or acknowledge his presence (been about two months)
He's one of those know it all, been there done that types. He's worked in the job 7 years less than me, but when told what to do and how to do said thing correctly he makes his own choice, makes a mistake...passes the buck and carries on as if nothing had happened.
Most recently he drove out the yard and hit the gate (turned too soon with his lorry) and kept going, pleading ignorance despite 3 of us seeing him hit the damn thing...nothing was done, a nice gouge out of the vehicle though. (drivers side as well LOL)
I work in Removals & Storage incase you were wondering.
I take it the boss man knows him in some form then because if all that is accurate then the guy shouldn't really have that job!

if he passes the jobs to you as an email (without CC the boss) then reply asking for reasons (with a CC to the boss)
^^Solves of the problem of getting him to cc the boss in the first place
