Are you covering 24/7/365? We have five shifts, our week hours are 32, 36, 48, 36, 48. One shift is always on days, one is always on nights. One shift is on “relief week”, which is the week with four eight hour days. If another shift was on vacation the relief shift would cover. Most take their relief week as vacation which means you can be off for 14 days straight with 32hrs vacation.
Yes, there are 5 of us on that rotation to give 100% supervision year ‘round. 2 or sometimes 3 days a week there are 2 duty engineers so one or the other can go around the campus checking, inspecting or repairing mechanical spaces and equipment. The senior guy usually gets to “escape” the plant. < BG >
