===Work patterns===
Typically, controllers work for 90 to 120 minutes followed by a 30-minute break.<ref>{{Cite web |last=Eurocontrol |date=26 Apr 2023 |title=GUIDELINES ON FATIGUE MANAGEMENT IN ATC ROSTERING SYSTEMS |url=https://skybrary.aero/sites/default/files/bookshelf/34421.pdf |archive-url=https://web.archive.org/web/20241219235017/https://skybrary.aero/sites/default/files/bookshelf/34421.pdf |archive-date=19 Dec 2024 |access-date=9 Feb 2025 |website=skybrary.aero}}</ref> Except at quieter airports, air traffic control operates 24/7, 365 days a year, requiring controllers to work rotating shifts that include nights, weekends, and public holidays. Shift schedules are usually set 28 days in advance.<ref>{{Cite web |last1=Arnvig |first1=Mette |last2=Beermann |first2=Beate |last3=Köper |first3=Birgirt |last4=Maziul |first4=Maren |last5=Mellett |first5=Úna |last6=Niesing |first6=Cees |last7=Vogt |first7=Joachim |date=14 Apr 2006 |title=Managing Shiftwork in European ATM: Literature Review |url=https://skybrary.aero/sites/default/files/bookshelf/5594.pdf |url-status=live |archive-url=https://web.archive.org/web/20241220094844/https://skybrary.aero/sites/default/files/bookshelf/5594.pdf |archive-date=20 Dec 2024 |access-date=9 Feb 2025 |website=Eurocontrol}}</ref> In many countries, the structure of controllers' shift patterns is regulated to allow for adequate time off. The shift pattern often varies depending on country, facility and its location. In the US the FAA regulates the hours that an air traffic controller may work. Controllers may not work more than 10 straight hours during a shift, which includes required breaks, and must have 9 hours of rest before their next shift.<ref>{{Cite web |title=Air Traffic Controllers |url=https://www.bls.gov/ooh/transportation-and-material-moving/air-traffic-controllers.htm#tab-3 |access-date=2025-04-12 |website=Bureau of Labor Statistics |language=en-us}}</ref> In the US air traffic controllers usually work a relatively unique rotating shift schedule, called the 2-2-1. Working the 2-2-1 means rotating between two afternoon shifts, two morning shifts and a midnight shift over the course of a week.<ref>{{Cite web |title=Wayback Machine |url=https://www.faa.gov/sites/faa.gov/files/data_research/research/med_humanfacs/oamtechreports/AM95-19.pdf |archive-url=http://web.archive.org/web/20250322043836/https://www.faa.gov/sites/faa.gov/files/data_research/research/med_humanfacs/oamtechreports/AM95-19.pdf |archive-date=2025-03-22 |access-date=2025-04-12 |website=www.faa.gov}}</ref>
