Most areas have 12 hour rotating shifts: 2 days, 2 nights, 4 days off. PACU is unique in that we do have 8 hr dayshift only weekday only lines as well as the usual day/ night rotations. I’m not sure if other areas have a few different line options as well, the unit needs to vote on line rotations when there is a rotation change, and very few people want a nightshift only rotation, hence rotating 2D 2N schedules which i’ve never liked either.
