6 on, 2 off, 12 hours, straight mids, no rotation: much less bad.

I've done all of the above but the 12 hour shift and can add 5 on, 2 off, 8 hours, rotating between swings and mids. They sucked. I'm in general agreement with Mike's judgments as well.

If you want to be fair to your people and help keep their morale up, straight shifts is the way to go - or at least fix the mids shift and make the swing/mids switch at 2200 (10pm). Changing sleep times is the quickest way to get zombies for employees.

If you try to do a 6 and 2 style rotation, eventually some smart person is going to figure out that they're getting screwed out of a lot of weekend and holiday time as opposed to the "daybeggers."

My recommendation, based on 10 years of this nonsense in the Army, is minimum 2 people per shift, 5 on, 2 off, stagger the weekends so that someone gets Fri-Sat, the other Sun-Mon. If they can decide which wants which weekend between themselves, so much the better.

As the FAA has lately demonstrated, single person night shifts is generally a bad thing if you actually want them to stay awake.
