It's called shift work. Most shift workers on a rotating roster would love only one night in six. And to be honest, it's not really ALL night is it?
actually, most shift workers prefer doing a cycle of nights because it means they don't have to do it again for a month or so, and they actually get into some kind of rhythm with their sleep cycles, instead of trying to sleep at a different time each day!
and yes, once you take in to account travelling time (an hour sounds fair) on either end of the shift, it is all bloody night!
so what part of the AWB do you work in,
Traffic_Is_Er_Was?
ps. how the hell do you call 4 shifts over 4 days and 2 days off, rinse & repeat a
basically 4on, 4off cycle
