Rotating shift schedules

What is a rotating shift schedule?

On a rotating schedule, you don't work the same hours every week. Instead, you follow a repeating cycle — for example a week of days, a week of evenings and a week of nights, or blocks of 12-hour days and nights. Rotations let a business run around the clock while sharing nights, weekends and holidays fairly across the team.

Common shift hours

Start times vary — 6:00, 6:30 and 8:00 AM are also common. 24-hour shifts (fire departments) usually run 7:00 or 8:00 AM to the same time next day.

Types of rotation

• Fast vs slow: fast rotations change shift every 2–3 days (continental); slow rotations stay on a shift for a week or more (southern swing).
• Forward vs backward: forward goes day → evening → night, which most sleep researchers consider easier to adapt to.
• Rotating vs fixed: in some patterns teams rotate between days and nights (2-2-3 Panama, DuPont); in others the days off rotate but the shift is fixed (Pitman).

How many people does 24/7 coverage need?

A week has 168 hours. Divide by the average weekly hours of your rotation to get the number of teams:

For more than one person per shift, multiply the team size. Plan names and coverage with the schedule maker.

Staying healthy on rotating shifts

Rotating and night work disrupt the body clock. Keep a dark, quiet bedroom, protect a regular block of sleep, use light and caffeine strategically, and plan recovery days after night blocks. Our night shift sleep schedule guide has example sleep plans.
