  • working an expected 9 hours per weekday other than Friday
  • working 8 hours on every other Friday
  • getting every other Friday off
  • a weekly definition of Friday to Friday (instead of Monday to Sunday or Saturday to Friday).
    • the week begin is often sometime midday Friday
      • the 9/80 week, therefore, would run noon Friday to noon Friday
