Rotas in which shifts are of different lengths. Usually a combination of 8hr and 12hr shifts, but could entail other combinations. There are two basic types. Namely:

  • Variation by day in the week. A change in shift length by day in the week. For example, with a continuous system generating 24hrs cover for seven days a week, a switch from three, 8hr, shifts a day on a weekday, to two, 12hr, shifts a day at weekends. The net result of the switch, is to increase the numbers of weekend days off over the shift cycle.
  • Variation by time of year. A change in shift length at specific times in the year. Normally confined to annual hours rotas which have one or more sub-rotas generating extended rest periods. For example, with a continuous system generating 24hrs cover seven days a week, a switch from three, 8hr, shifts a day during the basic rota, to a sub-rota based on two, 12hr, shifts a day during the Summer. This sub-rota generating one extended rest period of at least two weeks per team / employee. The net result of the switch, is to offset the reduction in the rest period between blocks of shifts that would have occurred if 8hr shifts had been worked throughout the Summer period.
