A workweek is a regularly recurring period of 168 hours (seven consecutive 24-hour periods). It is a fixed amount of time, meaning it cannot be moved to avoid paying employees overtime.
A workweek can start on any day and at any time, meaning it does not have to follow a standard calendar week. Creating a workweek helps employers know when they must start paying their employees for overtime work. While a workweek cannot be changed to avoid paying overtime compensation, it can be changed if the change is intended to be permanent. Different workweeks can be created for different employees, groups of employees, and business locations.
