4317:, in which shift workers generally are allowed every other Friday, Saturday, and Sunday off, with two additional days off during the week, although this may differ depending on organization and industry. The most common form utilizes four shifts, each working twelve hours, with two shifts generally paired together: A working days and B working nights while C and D are off, and vice versa. It is not uncommon for shifts to rotate between days and nights, most often with six months spent on nights and six on days. This shift is sometimes known as the 2-2-3 or "two, two and three".
3697:. An employee works for four days, usually in 12-hour shifts (7:00 to 7:00) then has four days off. While this creates a "48-hour week" (42-hour average over the year) with long shifts, it may be preferred because it shrinks the work week down to four days, and then gives the employee four days' restβdouble the time of a usual weekend. Due to the plan, employees effectively work an eight-day week, and the days they work vary by "week". As with three-shift systems, most employees stay with the same shift rather than cycling through them.

accidents plus more rest for employees, less call ins, and more coverage when crews are short handed. In all the schedule is designed to improve safety. A particular advantage of this plan is that it can readily be slewed to fit business requirements. For example, if less coverage is required on a Sunday, stand-alone shifts are avoided by scheduling the fourth night and first day of four on that day. This also has the additional benefit of the quick turnaround day between three shift days and nights also falling on a Sunday.
7681:, however, when firefighters work it, the shifts rotate from day to night between every break. Since the firefighters have a two-day break before any nights worked, they do not start the series of nights with an employment-related sleep deficit. They do work three nights in a row, which would result in chronic sleep deficit if alarms are received on each night, however, the third night is always a Sunday night, which is often less busy than other nights of the week. This schedule allows for a long break every other weekend.

each firefighter in the work group, frequently reducing a 56-hour workweek to a 48-hour workweek by scheduling a 24-hour "Kelly Day" every three weeks. Departments have many options for scheduling firefighters for coverage. One option is 24 on/48 off, where a firefighter will work 24 hours and have 48 hours off, regardless of the day of the week or the holidays. Often they will be scheduled in an AβBβC pattern. Thus, a firefighter will be assigned to A, B or C shift and work whenever that letter is on the calendar.

2005 Canadian
Firefighter study comparing two models with 24-hour shifts with three models requiring at least three consecutive night shifts, found that consecutive nights were shown to be more deleterious to performance than a single, long shift. Performance effectiveness 75% after two consecutive nights and lower after three, compared to 78% for a 24-hour shift. If the schedule induces sleep deficit in a subsequent day shift, this performance would be worse.

emergency services, crews are encouraged to rest if required). Conversely, those employed on high demand days such as weekend nights, or in particularly high demand areas, will often be required to be awake or working for their entire rostered shift. However, due to the scheduled nature, most ambulance and fire employees can attempt to obtain sufficient rest before or after a particularly busy 14-hour night shift.

5205:. The benefit to working an extra hour a day gives you a normal 2-day weekend followed by a long 3-day weekend the next. Typical working hours for this type of shift would be 06:00 to 15:30 (9 hours with 30 minutes lunch) and 06:00 to 14:30 (8 hours with 30 minutes lunch) on the 8-hour work day. Often the employer will alter the starting times (e.g., start at 07:00 or 08:00).

This change, along with first shift moving a half-hour later, or second moving a half-hour earlier, ensures at least a half-hour overlap between shifts, which might be desirable if the business is open to the public to ensure that customers continue to be served during a shift change.

In other fire departments, firefighters work shorter shifts, such as a mix of 10-hour day shifts and 14-hour night shifts. The advantage is that firefighters have shorter working hours. The disadvantage is that they may sometimes have only 12 hours to recover between one night shift and the next. The

Most departments split the 168-hour-long week between 3 or 4 work groups (sometimes referred to as 'shifts' or 'platoon groups'), resulting in a 56- or 42-hour workweek, respectively.

The 8-day week with 21 hours per "day" is a general concept for full week coverage where the 168 hours of the week are grouped differently.

plan there are 24 consecutive shifts of 7 hours per week, hence covering 24/7. With 4 groups and 6 shifts per group, the work time is 42 hours per week.

To provide an overlap in shifts, some employers may require one of the shifts to work four 10-hour shifts per week (as opposed to five 8-hour shifts, both are 40 hours per week). In that scenario, the night shift might extend from 21:00 to 07:00, but the night- shift would have nearly four days off

the employee only gets one day off after a work streak of four days. There are 28 shifts per employee in a five-week cycle (i.e. 35 days).

Note that a worker transitioning from N to O works for the first six or seven hours of the first day "off". Thus, when days off follow night shifts, the first one or more days "off" are, in fact, days of recovery from lack of nighttime sleep. This daily notation refers to the start of a shift. If a

The most basic three-platoon schedule is a straight rotation of 24-hour shifts among three platoon groups. This rotation limits time off to 48 hours in a row, less than 66 hours off in a row most workers get each weekend. Workers on this schedule only get one short weekend off every three weeks.
6997:
This rotation reduces the chronic sleep deficit accrued over the first two work days at the expense of a shorter long break. This schedule's long break coincides with a standard weekend exactly once every nine weeks. The four-day break could be retained by working a fourth day in the rotation -

hours per week with 8-hour shifts. Three groups are needed for each time span, i.e. to cover the whole day and week a company needs 6 groups for 12-hour shifts or 9 groups for 8-hour shifts. This plan is mainly adopted by industries in which employees do not engage in much physical activity.
