Five 8 AM–5 PM shifts with a 30-minute unpaid break add up to 42:30 hours. Under the federal Fair Labor Standards Act, non-exempt employees must be paid at least 1.5 times their regular rate for hours over 40 in a workweek, so 2:30 of that week is overtime. Federal law counts by the week, not the day.
California also counts overtime by the day: hours over 8 in a workday are paid at 1.5 times the regular rate. This shift has 8:30 of paid time, so 0:30 of it is daily overtime in California even if the week stays under 40 hours. Most other states follow only the federal weekly rule.
California requires a 30-minute meal period for any work period over five hours, so a lunch break is expected on this shift. Federal law does not require meal breaks, but where one is given and you are fully relieved of duty for 30 minutes or more, it is usually unpaid.
Five of these shifts give about 42.5 paid hours a week. For employer health coverage under the Affordable Care Act, the IRS treats an employee as full-time at an average of at least 30 hours a week (130 hours a month). By that measure this schedule is full-time. Employers set their own full-time definition for other benefits.
8 AM to 5 PM is 9 hours (08:00 to 17:00 in 24-hour time).
