PTO on 12-hour shifts
Paid time off is usually counted in hours, so each 12-hour shift you take off uses 12 hours. 80 hours of PTO, two weeks for a weekday worker, is only 6.7 twelve-hour shifts. Because you work fewer days, though, those shifts cover more calendar days off.

PTO hours to shifts
| PTO hours | 8-hour days | 12-hour shifts | 24-hour shifts |

| 80 | 10 | 6.7 | 3.3 |

| 200 | 25 | 16.7 | 8.3 |
Why it still goes further than it looks
On a 12-hour rotation you work about half the days of the year, so the days off around your leave are already long. On a Pitman, taking the 3 shifts of one Friday-to-Sunday block gives you 7 days off in a row. On a DuPont, 4 shifts of leave next to the 7-day break give 14 days. On a 3 on 3 off, 3 shifts give 9. Use the shift calendar to see where your blocks fall before you book.
How PTO accrual works
Most employers accrue PTO per hour worked. A plan that gives 80 hours a year for 2,080 hours worked accrues about 0.0385 hours per hour (80 ÷ 2,080). On a 12-hour rotation with 2,184 scheduled hours, the same rate gives about 84 hours. Some plans cap the balance or accrue per pay period instead; your handbook says which.
Federal law does not require paid vacation or sick leave: the FLSA “does not require payment for time not worked, such as vacations, sick leave or federal or other holidays” (US Department of Labor). Some states and cities require paid sick leave, and PTO plans are set by the employer or union contract.
Tips for 12-hour workers
- Ask whether a holiday you work is paid extra or adds PTO; see the 2027 federal holidays.
- Check whether PTO counts as hours worked for overtime: under federal rules, paid leave hours do not count toward the 40.
- For the year's hours and pay of your pattern, use the shift pay calculator.
