Mine is great..
I work 24 hour shifts.
24hrs on then 48hrs off. One day on, two days off....
Works out great considering every three weeks, 3 24hr shifts fall into a one week period and the job decided that it's way too much overtime, so they give us one of those days off.
So that's about... 8 days a month. Still running you 48hrs a week.
I like it.
