DuPont schedule

Quick answer: the DuPont schedule is a 28-day rotation for 4 crews on 12-hour shifts: 4 nights, 3 off, 3 days, 1 off, 3 nights, 3 off, 4 days, 7 off. Each crew works 14 shifts every 4 weeks, 42 hours a week on average, and gets 7 days off in a row once a cycle.

What workers say about DuPont

The draw is the 7-day break every four weeks, long enough for a trip without using vacation. The cost is the block before it: 4 day shifts after 3 nights, and one week that reaches 72 hours if the workweek starts on the first night. Changing between nights and days every few shifts is harder on sleep than fixed shifts.

The DuPont "hell week"

Workers call the heaviest stretch the hell week: depending on where the workweek starts, one week reaches 72 hours (6 shifts of 12). It comes right before the 7 days off, which is what makes the schedule popular despite it. If your employer starts the workweek elsewhere, the heaviest week can be 48 or 60 hours instead; the table above shows every option.
