A part-time employee works fewer hours than the employer’s full-time schedule. There is no single federal definition, and different laws use different hour counts, so the label matters less than the hours actually worked.
| Rule | Threshold | Counted how |
|---|---|---|
| Overtime (FLSA) | Over 40 hours in a workweek | Each workweek |
| ACA full-time status | Average of 30 hours a week | Hours of service over a measurement period |
| FMLA eligibility | 1,250 hours in the previous 12 months, plus 12 months employed | Hours actually worked |
| Company benefits | Set by the plan | Per the plan documents |
Because these tests use hours, not titles, accurate time records are what decide who qualifies. See full-time hours.

A pharmacy chain classifies a cashier as part-time and excludes her from its health plan. Her schedule says 24 hours, but she picks up open shifts and her time records show she averaged 32 hours a week over the past year, 1,664 hours in total.
For the ACA, if the chain is an applicable large employer, what matters is her hours of service, not her title, so she would count as full-time for that year’s measurement. For the FMLA, her 1,664 hours are well over the 1,250-hour test, so she is eligible if the worksite is covered.
The chain reviews every part-time employee’s actual hours each quarter, offers coverage where the hours require it, and updates its scheduling so part-time roles that are meant to stay under 30 hours actually do.
Part-time employees often juggle school, care or a second job, so predictability matters more than the exact number of hours. Collect availability, post schedules early, and offer extra hours through one open process so the same few people do not get them all. Track average hours per person over time, because a part-timer who regularly works 35 hours may cross benefit or legal thresholds.
Include part-timers in communication and training on the same terms. They are often the people who cover nights and weekends, when managers are not around, so missing them means missing key parts of the business.
A retailer hires a part-time associate for 20 hours a week. Over six months, because she always says yes to extra shifts, her average reaches 33 hours.
The retailer’s monthly hours report flags her average. HR confirms how the hours affect her benefit eligibility under the plan and under the ACA measurement rules, offers her the coverage she now qualifies for, and asks whether she wants to keep the extra hours. She does, and her status is updated in the system.
The FLSA does not define it. Employers set their own definition, often under 30 or under 35 hours a week, while specific laws such as the ACA use their own thresholds.
Yes. Non-exempt part-time employees are owed overtime for hours over 40 in a workweek, like anyone else.
They can be, with 12 months of employment and at least 1,250 hours in the previous 12 months at a covered employer and worksite.
It depends on the plan and on ACA rules for larger employers, where an average of 30 hours a week makes someone full-time for coverage purposes.
Yes. Many employers offer full-time roles to part-timers first. Check how the change affects benefits, pay group and schedule.
It depends on the employer’s policy. Federal law does not require holiday pay for any employee.
