This does not apply to the attached air wing, which will work a 12 on, 12 off schedule 7 days a week. The Surface Fleet began its shift in 2017, transitioning from their "five and dimes" approach of 5 hours on, 10 hours off. This does have the side effect of sailors assigned to a certain shift having the same meals every day, and so the shifts are periodically rotated in order to provide variety. This gave rise to a schedule of six on, twelve off, six on, thirty off, six on, twelve off.īeginning in 2014, the Submarine Force began shifting to a 24-hour day, with watches split into 8 hours on, 16 hours off. He would stand the same 6-hour watch in a given 24-hour period, usually from midnight to 06:00 (hence the midnight portion of the name, often shortened to cowboy) and the normal watchstander would then be free. With sufficient personnel, a given watchstation may benefit from a fourth man (the midnight cowboy or "Balls-to-6"). During off time the sailor has time to sleep, relax, and perform personal tasks, such as laundry. During the off shift there is time to perform maintenance, study for qualifications, and handle collateral duties. Navy used a three shift system with an 18-hour day instead of a 24-hour day. DNOO is the preferred sequence because days off follow night work and there are two consecutive days off. Within a set, DONO has the same sequence as NODO. For example, the twelve-hour, 2 nW:2 nF system with n = 1 allows twelve different plans in three serially-identical sets. One shift system may allow many shift plans. The day after this shift is an F day if no shift starts on this day, though many hours have been worked from midnight on. If a shift starts at 23:00, then this is a W day even though only one hour is worked. This daily notation refers to the start of a shift. 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. Note that a worker transitioning from N to O works for the first six or seven hours of the first day "off". A~F work teams (starts from A as first team) O days off This is defined as a day on which a shift does not begin. N night shift, 3rd shift, graveyard shift This shift often occurs from either 22:00 or 23:00 to either 06:00 or 07:00 for eight-hour shifts, and from 18:00 to 06:00 for twelve-hour shifts. S swing shift, 2nd shift, late shift, afternoon shift This shift often occurs from either 14:00 or 15:00 to either 22:00 or 23:00 for eight-hour shifts, and is not used with twelve-hour shifts. The shift plan determines the sequence of work (W) and free (F) days within a shift system.Ī notation used often identifies day (D), swing (S) and night (N) shifts for the W days and O (off) for rest days.ĭ day shift, 1st shift, early shift This shift often occurs from either 06:00 or 07:00 to either 14:00 or 15:00 for eight-hour shifts, and from 06:00 to 18:00 for twelve-hour shifts. The schedule includes considerations of shift overlap, shift change times and alignment with the clock, vacation, training, shift differentials, holidays, etc. British) is the central component of a shift schedule in shift work.
