The rule is older than your grandparents and it hasn't changed: work more than 40 hours in a single workweek and your employer owes you at least 1.5 times your regular rate for every hour past 40. That's the Fair Labor Standards Act, on the books since 1938.
It covers most hourly workers automatically. If you're salaried but earn less than $684 a week ($35,568 a year), you're owed overtime no matter what your job title says. Above that salary line, your employer can call you "exempt" — but only if your actual day-to-day duties fit one of the narrow categories the DOL spells out (executive, administrative, professional, computer, or outside sales). The label isn't enough; the duties have to match.
One thing worth knowing: the DOL tried to raise the salary threshold to $58,656 in 2024, which would have pulled millions of mid-level salaried workers back into overtime eligibility. A federal judge in Texas vacated the rule in November 2024, so the line is still $35,568 going into 2026.
