How it works
Shift = end − start (adding 24 hours if the shift crosses midnight). Paid hours = shift − unpaid break. Pay = paid hours × hourly rate. Pay not received = unpaid break × hourly rate.
Worked examples
- 8:00 to 16:30 with a 30-minute unpaid lunch at $18: 8:30 shift, 8:00 paid, $144.00 pay, $9.00 not paid.
- 22:00 to 06:00 with a 15-minute unpaid break at $20: 7:45 paid, $5.00 not paid, but a 15-minute break is usually paid rest time under federal rules.
- A 45-minute unpaid lunch on a 9-hour shift leaves 8:15 paid.
Common questions
Does my employer have to give me a lunch break?
Federal law does not require one. Some states do, often after 5 or 6 hours of work; see the state table linked on this page and your state labor office.
Can my employer take 15 minutes off for a short break?
Under federal rules short breaks of about 5 to 20 minutes count as hours worked, so they should be paid.
When is a lunch break paid?
When you are not fully relieved of duty, for example if you eat at your desk while answering the phone or must stay at your machine, the time is work time and is paid.
