This is a great overtime question. The Fair Labor Standards Act (FLSA) allows for employers to round to quarter hours (15 minute increments) when calculating overtime. However, if an employer continuously uses the practice of rounding down (not compensating you for say 10 minutes extra each day), this could lead to possible FLSA violations, since the employee is not being compensated for hours worked over a period of time. I recommend that you contact an attorney if you are continuously working time for which you are not compensated, to better understand your rights.
