For what it's worth, was part of a datacenter operations department that 
had a 24x7 team.  4 shifts, 4 staff on each shift (1 was supervisor who 
did same work as the rest, 1 'point of contact' who stayed in the office).
4 days on, 4 days off, 12 hour shifts, 8-8.  Shift teams would alternate 
between day and night (so 4 day, 4 off, 4 night, 4 off, repeat ad 
infinitum).  During the day that was bolstered by 6 day-staff, Monday to 
Friday, who would have a staggered start through the day (IIRC 2 start 
at 8, 2 at 9, 2 at 11)
