"Under the US Fair Labor Standards Act (FLSA), non-exempt employees must receive overtime pay for hours worked over 40 in a workweek at a rate not less than time and one-half (1.5x) their regular rate of pay. Accurate daily time tracking prevents wage disputes and payroll calculation errors."

Frequently Asked Questions
How do you calculate work hours with lunch breaks?
Subtract your start time from your end time to find total elapsed time, then subtract your unpaid break duration in minutes. For example: 9:00 AM to 5:30 PM is 8.5 hours (8 hours 30 mins). Deducting a 30-minute lunch break leaves exactly 8.00 billable work hours.
