> When I get new staff, the most difficult thing to teach them is that if they have completed a task that had been given to them, that they have to hand in the work and ask for a new task. But it gets even worse. Many times, if they run into a problem in the task they just give up and don't tell anyone. When you ask them what happened, they give you a blank look and say something like, I couldn't open the file. So instead of asking someone for help they spent the next three hours on facebook until a manager noticed. Very frustrating.

I'm sure that's completely down to a lack of thinking for oneself, and not, say, a stronger desire to be on Facebook than to do one's job ;)
