You do 5 horrifically early starts in a row, but it's OK as it's been scientifically proven to not induce fatigue. You then lie on the couch for 2 days while your wife and kids complain about the job you do, and then you get to work another 5 days reporting either mid morning or after lunch, and you get home around midnight, give or take an hour or two. You then enjoy 4 days off. The first usually spent transitioning between the bedroom and the couch. But it's a great improvement on what we had before!
If only I could remember what life was like before!
Seriously, as a married guy with kids, personally I think the roster a real tragedy, but there are plenty of guys/girls out there who love it. Probably suits the singles better.
