<human>: So I was promoted to supervisor of a mailroom team in a large company. As part of my promotion, the company hired a new guy in my old position. His third day on the job, I can say with absolute certainty that he absolutely SUCKS! And his BO is unbearable...

No motivation, slowest learner ever (I need to be careful here because he may have a learning disability) and he keeps insisting on taking his HR-guaranteed 15 minute breaks (he took five yesterday...I counted).

The problem is -- he used to work for my boss, who absolutely LOVES him. I DON'T KNOW WHAT TO DO. I can't do my job because he's refusing to do his!

Could you distill the essence of the text into 1-3 sentences?
<bot>: I am supervising a mailroom team, and the newest employee doesn't do shit. But he is my bosses friend so I can't say or do anything. HELP!
