“[T]he 9/80 work week…occurs over a 2-week period as follows: employees work eight 9-hour days in a 2-week period, one 8-hour day and then receive one “free” day off every other week.” (United States Environmental Protection Agency, 1998)
“A “9/80 schedule” means that on 4 days per week you work 9 hours, and on the 5th you either work 8 hours or you have a day off. So for example, you may work 9-hour days Monday through Thursday, and on Fridays, you either work an 8-hour day or take the day off. 9/80 means that you work 80 hours over 9 days, instead of the traditional 10.” (Flexibility, 2005)
“9/80 Compressed Work Week Employees work 80 hours over a 9 day period instead of 10. The typical work day is 9 hours.” (Commuter Choice Primer)
