What about lunch?
Deducting an unpaid lunch break changes your paid hours:
| Lunch break | Paid hours | Decimal |
|---|---|---|
| None | 12 hours | 12.00 |
| 20 min * | 11h 40m | 11.67 |
| 30 min | 11h 30m | 11.50 |
| 45 min | 11h 15m | 11.25 |
| 60 min | 11 hours | 11.00 |
* Breaks under ~20 minutes are generally paid time under the FLSA — short breaks usually can't be deducted. Meal periods of 30 minutes or more are generally unpaid when you're fully relieved of duties (29 CFR 785.19).
