You normally get 5+ hours guarantee for 1.5 - 3 hours worth of block. You get 50-80% of your sleep while on duty. Home all day.

They normally go very senior... some people like the time off, others actually have day jobs or businesses.

Now there are some 2-4 leg backside schedules with no opportunity to nap, which truly suck... that's a graveyard shift. I vastly prefer redeyes or standups to that sort of crap.
