'''Shift work''' is an employment practice designed to keep a service or production line [[24/7 service|operational at all times]]. 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.<ref>{{cite web |url=http://workfamily.sas.upenn.edu/glossary/s/shift-work-definitions |title=Shift work, Definition(s) of |access-date= 2014-09-25 |author1=Sloan Work  |author2=Family Research, Boston College |name-list-style=amp }}</ref><ref>{{cite web|url=https://www.iwh.on.ca/summaries/issue-briefing/shift-work-and-health|title=Shift work and health|author=Institute for Work & Health, Ontario, Canada|date=2010|access-date=2018-08-05|quote=...employment with anything other than a regular daytime work schedule}}</ref><ref>{{cite web|url=http://www.princeton.edu/~ota/disk1/1991/9108.html|title=Biological Rhythms: Implications for the Worker|year=1991|author=U.S. Congress Office of Technology Assessment}}</ref>
