part-timers are better employees first of all because they are more discipline. Second, part-timers focus on the job rather than their own psychological needs. Someone who writes a novel out of hours – or looks after children, or scales cliffs on Fridays – is less likely to have a mental breakdown over the company’s decisions. There is just one problem with hiring part-timers. The obsessive full-timers. They dislike the idea that someone else has a life outside work; they complain about absent part-time colleagues.
