A pattern of work in which the starting time of successive rostered shifts, or blocks of rostered shifts, changes in a clockwise direction.

For example, with a three (8hr) shift a day system, generating 24hrs cover for 7 days a week, and shifts worked in blocks of six;

1. Within a block of shifts. Two Morning shifts followed by two Afternoon shifts and then two Night shifts.
2. Across blocks of shifts. A block of six Morning shifts is followed by a block of six Afternoon shifts and then a block of six Night shifts.
