A flexible work schedule is an alternative to the traditional 9 to 5, 40-hour work week. It allows employees to vary their arrival and/or departure times. The Fair Labor Standards Act (FLSA) does not address flexible work schedules.
A normal work shift is generally considered to be a work period of no more than eight consecutive hours during the day, five days a week with at least an eight-hour rest. Any shift that incorporates more continuous hours, requires more consecutive days of work, or requires work during the evening should be considered extended or unusual.
