Ok... so I had a 1-1 meeting today with that sook about something completely different than the work he try to flick-off when he took a sickie on Friday. After we finishing discussing our original topic, he brought that up. I told him that his supervisor gave him specific instructions from me not to delegate the work to other staff members, because they were already under the pump, and it wouldn't be fair for them to get additional work and no reward for it. Then again, I had to bring up his laptop and phone and call-in if something was urgent that he couldn't do at home.
The guy walked away from the meeting without a further word on the matter, meaning he knew I had a point and he was in the wrong.
