I work 2 days 2 nights 4off and to me it is the best shift to work. Only 2 early mornings then the 2nights, which are easier to get through than 4 nights especially if you cant sleep that well during the day. I turned a job down with Rich's airline because the shift I was too work was the 7 on 3 off, 7 on 4 off and I could see it would be a killer to work.
