Let the rotten be rotten

This guy is working under me. First impression was okay, later on become tortoise. Working slow, swing the clock or play snake 80% of the working hours. Reading novels everyday, nothing else he could do, read novel and work at the same time. Sometimes also mess up a lot of things. Plus, he is the most KBC person that I never seen before on Earth. Everytime I talk, there must be something to do with him, interupt my conversation. Or when someone is asking me something, then he answer for me. My poor colleague who sat next to me doesn't have his own privacy anymore. Everytime he checks his mailbox or types messages in MSN, he needs to be aware. Everything seems transparent beside him, so he needs to act quickly to minimize his browser before he sees them. The most of his time is spent on KBC, that's why his working speed is superslow. My other colleague told me that the boss is complaining about his working speed. I don't really care him anymore eventhough he is under me, let it be. Let him die. One more thing, I remember that day when we were rushing our work, I asked him to finish that task on that day, it was urgent. I still saw him spending his time on reading novels.
