I am a night dispatcher for a trucking company, and I do my work from home. Mostly it's answering the phone and telling the drivers where to go, but I also have to keep up with paper work and do some computer work. I work from 4pm-8am, I can sleep when I get things mostly lined out (usually 2am), but I still have to get up if I get a call. And I work Weekends til all the drivers are in, which could be anywhere from Friday night to Sunday morning.
I guess the only down sides is I can't go anywhere that the phone won't reach, and I have to listen to the drivers complain about how horribly they are treated and how I save all the good loads for my favorite drivers.
