Shift work is an employment practice designed to make use of, or provide service across, all 24 hours of the clock each day of the week (often abbreviated as 24/7). The practice typically sees the day divided into shifts, set periods of time during which different groups of workers perform their duties. The term "shift work" includes both long-term night shifts and work schedules in which employees change or rotate shifts.
In medicine and epidemiology, shift work is considered a risk factor for some health problems in some individuals, as disruption to circadian rhythms may increase the probability of developing cardiovascular disease, cognitive impairment, diabetes, and obesity, among other conditions.
Shift work can also contribute to strain in marital, family, and personal relationships.
Shift work increases the risk for the development of many disorders. Shift work sleep disorder is a circadian rhythm sleep disorder characterized by insomnia, excessive sleepiness, or both. Shift work is considered essential for the diagnosis. The risk of diabetes mellitus type 2 is increased in shift workers, especially men. People working rotating shifts are more vulnerable than others.
Shift work is an employment practice designed to make use of the 24 hours of the clock, rather than a standard 8 hour working day.

Shift-Work is a 1991 LP (13th) by the British rock band The Fall, released through Phonogram Records. The Fall started working on the album in 1990 while still touring in support of Extricate, however Mark E. Smith sacked guitarist Martin Bramah and keyboardist Marcia Schofield immediately after the Australian leg of the tour, reducing the lineup to the four-piece for the first time in band's history. Only one song ("Rose") from the sessions with Bramah and Schofield eventually appeared on the album (non-vinyl versions also included the single "White Lightning", originally recorded by The Big Bopper), while several more tracks were released as Dredger EP in August 1990, including "Life Just Bounces" which would later be re-recorded for Cerebral Caustic. The Fall's first release with a reduced lineup was single "High Tension Line" in December 1990.
Shiftwork marked, in the opinion of critic Ted Mills, a change in direction for the group, as "repetitious grooves became interspersed with pop song structures." Of the songs on the original tracklist, several have been noted as being more "introspective" than previous Fall efforts. "Edinburgh Man" for example, in which lead singer Mark E. Smith longs to be in the city of Edinburgh, Scotland has been described as "surprisingly malice-free" and, in one enthusiastic review, as the best Fall song ever.
