Overtime in the US
Under the Fair Labor Standards Act, non-exempt employees must be paid at least one and a half times their regular rate for hours over 40 in a workweek. Some states add daily overtime rules. See the U.S. Department of Labor overtime guidance. For a weekly timesheet with overtime pay, use the time card calculator.
Paid breaks and rounding
Short rest breaks of about 5 to 20 minutes are generally paid under federal rules, while meal periods of 30 minutes or more can be unpaid if the employee is fully relieved of duty. Check your employer policy and state law. For minutes-to-decimal conversion see the hours calculator.
