Notice of working hours/changes. Your employer must give you reasonable notice of any changes to your working hours, such as cancelling your shifts.

The amount of pay due an employee cannot be determined without knowing the total number of hours actually worked by that employee in each workweek. An employee must be paid for all of the time considered to be hours worked and all time that is hours worked must be counted when determining overtime hours worked. The Hours Worked Advisor will help employees and employers determine which hours an employee spends in work related activities are hours worked. The Advisor applies the principles involved in making that determination under the FLSA to common situations occurring in the workplace.
