Rapidly rotating 8-hour shifts cycling through earlies, lates, and nights every 2–3 days. Common in UK manufacturing, utilities, and process industries.

Three-shift rotating (10-hour)

Three overlapping 10-hour shifts per 24 hours, giving 6 hours of handover overlap across the day. Used in UK emergency departments, logistics control rooms, and process plants that prize rich handovers.
