Kentucky Labor Laws on 12-Hour Shifts: Breaks and Overtime

Kentucky labor laws allow 12-hour shifts for adults with no cap on daily hours and no premium for working past eight hours in a day. Overtime kicks in weekly, at time-and-a-half for anything beyond 40 hours in your employer’s fixed seven-day workweek. During a 12-hour shift you’re entitled to one lunch period and three paid 10-minute rest breaks, and if you work all seven days of a workweek you may be owed a seventh-day premium. Minors cannot legally work a 12-hour shift at all.

No Daily Overtime, Only Weekly

Kentucky does not require overtime pay for working more than eight hours in a day. A state regulation says so directly: an employer is not required to pay overtime for hours exceeding eight per day, or for work on Saturdays, Sundays, holidays, or regular days of rest.¹ The only overtime trigger that matters is weekly.

Under KRS 337.285, hours worked beyond 40 in a single workweek must be paid at one-and-a-half times the regular hourly rate.² The workweek is any fixed, recurring seven-day period the employer chooses. It doesn’t have to run Monday through Sunday, but once set it stays set.

For 12-hour shift workers the math is clean. Three 12s in a week is 36 hours: no overtime. Four 12s is 48 hours: eight hours of overtime. Paid time off, holidays, and sick days you didn’t actually work do not count toward the 40-hour threshold; only hours you were on the clock and working push you into overtime territory.¹

Kentucky’s minimum wage is $7.25 per hour. At that rate, overtime pays $10.88. If you earn more, the overtime rate scales up from your regular rate.

Your Lunch Period on a 12-Hour Shift

Kentucky requires employers to provide a reasonable lunch period, scheduled no earlier than three hours and no later than five hours after your shift starts.³ Employers covered by the Federal Railway Labor Act are the only exception.

Here’s the gap that catches 12-hour shift workers off guard: the statute requires one lunch period, and it has to fall in that three-to-five-hour window near the start of the shift. Kentucky law does not require a second meal break later. After lunch ends around hour four or five, you could legally work another seven or eight hours without another meal break. Some employers voluntarily offer a second one. The law doesn’t force them to.

Whether the lunch period is paid depends on what you actually do during it. Under federal standards, a meal period of 30 minutes or more is unpaid only if you’re completely relieved of all duties. Eating at your workstation while answering phones or watching equipment means that time counts as hours worked and must be paid.⁴ This is one of the most common wage violations in workplaces running 12-hour shifts. The break is recorded as unpaid, but the employee never actually stops working.

Three Paid Rest Breaks Per Shift

Separate from the lunch period, KRS 337.365 requires a paid rest break of at least 10 minutes for every four hours worked.⁵ A 12-hour shift earns you three of them. The statute is explicit that these breaks are in addition to the lunch period; they cannot be lumped together, skipped, or traded for an earlier clock-out. Pay cannot be reduced during the break for either hourly or salaried employees.

One exception: if a collective bargaining agreement already provides at least 10 minutes of rest per four hours worked, the employer can follow that agreement instead.⁵ Federal Railway Labor Act employees are also exempt. Everyone else on a 12-hour shift should be getting three paid 10-minute breaks. Employers who skip them can be investigated by the Kentucky Education and Labor Cabinet.

The Seventh-Day Premium

Kentucky has a separate overtime rule for employees who work all seven days of a workweek. Under KRS 337.050, if an employer allows an employee to work seven days in one workweek, the employee earns time-and-a-half for all hours worked on the seventh day.⁶

There’s an important limit: the rule doesn’t apply if you work 40 hours or fewer that week.⁶ Seven short shifts adding up to 38 hours doesn’t trigger it. But if you work seven days and clear 40 hours, you get the seventh-day rate on top of any standard weekly overtime owed under KRS 337.285.

Several categories of workers are excluded from the seventh-day rule, including supervisors and foremen whose primary role is directing other employees, Federal Railway Labor Act employees, workers at small telephone exchanges with fewer than 500 subscribers, and technical assistants of licensed professionals such as doctors, lawyers, and accountants.⁶

For 12-hour shift workers, the seventh-day rule tends to come up during high-demand stretches when an employer extends the rotation. Four 12-hour shifts already put you at 48 hours, so adding a fifth, sixth, or seventh day stacks overtime quickly.

On-Call and Waiting Time

Whether on-call hours count toward your 40-hour weekly total depends on how restricted you are. Under federal rules, if your employer requires you to stay on the premises while on call, that time is compensable and counts as hours worked. If you’re free to go home and simply need to leave a phone number, you generally aren’t considered to be working.⁴

The middle ground is where disputes happen. If you can leave the premises but face conditions that severely limit what you can do, like a 10-minute response window or a small geographic radius, those constraints can tip the balance toward compensable time. The more restrictions the employer places on your freedom, the more likely the on-call hours count as work. If those hours push you past 40 in a workweek, you’re owed overtime for the excess.

Who Is Exempt From Overtime

Not every employee qualifies for overtime, even after 40 hours. Under the federal FLSA white-collar exemption, salaried employees in executive, administrative, or professional roles earning at least $684 per week ($35,568 per year) are exempt.⁷ The job duties must actually fit the exempt classification. A job title alone doesn’t do it.

Kentucky’s own regulations exempt additional categories from state overtime, including retail employees whose principal duties involve selling, purchasing, or distributing goods; restaurant, hotel, and motel employees; motor carrier employees subject to federal Department of Transportation hours-of-service rules; auto, truck, and farm implement salespeople, parts workers, and mechanics at non-manufacturing dealerships; taxi drivers; residential child care workers providing 24-hour care at licensed nonprofit facilities; and in-home companion caregivers employed by third-party agencies to care for elderly or convalescing individuals. Retail, service, hotel, motel, or restaurant businesses with an average annual gross volume below $95,000 over the preceding five years are exempt from both minimum wage and overtime entirely.⁸

If you fall into one of these categories, your employer can schedule 12-hour shifts without owing overtime no matter how many hours you work in a week. Check where you stand before assuming you’re owed premium pay.

No Cap on Shift Length for Adults

Kentucky imposes no general limit on how many hours an adult can work in a single shift. The state’s overtime regulation confirms there is no absolute limitation on the number of hours an employee may work in any workweek, provided overtime is properly paid for hours beyond 40.¹ There is also no required minimum rest period between the end of one shift and the start of the next.

Commercial truck drivers and airline crews are the exception, because federal hours-of-service rules apply regardless of state law.⁹ For manufacturing, warehousing, retail, healthcare, and office work, there is no legal limit on shift length in Kentucky.

Minors Cannot Work 12-Hour Shifts

Everything above applies to adult workers. For employees under 18, Kentucky imposes daily and weekly hour caps that make a 12-hour shift illegal.

Workers aged 14 and 15 are the most restricted. On school days they may work no more than 3 hours per day and 18 hours per week. On non-school days they may work up to 8 hours per day and 40 hours per week. They may only work between 7:00 a.m. and 7:00 p.m., extended to 9:00 p.m. from June 1 through Labor Day.

Workers aged 16 and 17 have more flexibility but still face daily caps. On school days they may work up to 6 hours per day (6.5 with written parental permission) and 30 hours per week. On non-school days they may work up to 8 hours per day. Permitted hours run from 6:00 a.m. to 10:30 p.m. on nights before a school day (11:00 p.m. with parental permission), and from 6:00 a.m. to 1:00 a.m. on nights before a non-school day.¹⁰

The daily cap for any minor in Kentucky is eight hours. A 12-hour shift is never legal for a worker under 18, regardless of parental permission or time of year.

Filing a Claim for Unpaid Wages or Missed Breaks

If your employer has skipped overtime, denied your lunch period, or shorted your paid rest breaks during 12-hour shifts, you can recover back wages plus liquidated damages equal to the unpaid amount, effectively doubling the recovery.¹¹

Kentucky employees have three years from the date of the violation to file a wage claim. Claims can be filed online through the Kentucky Education and Labor Cabinet’s Workplace Standards division or pursued through a private civil action. Once that three-year window closes, the claim is gone regardless of its merit, so keep track of your dates and act while the record is still fresh.
