About the 4 on 4 off schedule
In a 4 on 4 off rotation you work four 12-hour shifts, take four days off, work four shifts of the other type, then take four more days off. Four crews share the pattern so the site is covered around the clock.
The cycle is 16 days long. Each crew works 8 of those days, which averages 42 hours a week. The longest stretch on and the longest stretch off are both 4 days.
Employers use several versions of this pattern. Some split each block differently, so line the calendar up with your posted schedule before you plan around it.
