Within blocks of shifts, patterns of rotation that do not cover all types of shift within the overall rota.

For example, with seven day continuous rotas based on three (8hr) shifts a day, in addition to no rotation, there are three further main types of rotation within blocks of shifts. Namely, a forward rotation (MAN), a semi-backward rotation (MNA), or a backward rotation (NAM). Mixed rotations occur when there is either two or more of these various types of rotation within the overall rota; all or some blocks of shifts do not contain all types of shift; or, some combination of the two. Mixed rotations are most prevalent with hybrid systems that incorporate a combination of three (8hr) and two (12hr) shifts a day.
