I worked the 12 hour rotation in Aviation before I left the department. Loved it. Only worked 14 days a month. 180 days a year. 2 on, 2 off, 3 on, 2 off, 2 on, 3 off.

Simpled down to weekly
Week one Worked M/T/F/S/S with W/TH off
Week two worked W/Th with M/T/F/S/S off

No for everyone, but you really do get a lot of time off. Longest stretch worked is 3 days with a 2 day break on the front and back of that three day stretch.
