Oregon Break Laws: How Many Breaks in a 12-Hour Shift

On a 12-hour shift in Oregon, you are entitled to three paid 10-minute rest breaks and one unpaid 30-minute meal period. Oregon break laws for 12-hour shifts come from Oregon Administrative Rule 839-020-0050, enforced by the Bureau of Labor and Industries (BOLI), and the details around timing, pay, and when a meal break turns into paid time matter more than most workers realize.¹

Three Paid Rest Breaks

Oregon uses a “major fraction” rule: you earn one paid 10-minute rest break for every four hours worked, or for any portion greater than two hours past a full four-hour block. BOLI’s own chart confirms it. Any shift between 10 hours 1 minute and 13 hours 59 minutes earns exactly three 10-minute rest periods.²

Each rest break has to be 10 continuous minutes with you fully free from work duties. Your employer cannot deduct the time from your pay or ask you to clock out. Rest breaks count as hours worked and are paid at your regular rate. The federal Department of Labor treats short breaks of roughly 5 to 20 minutes the same way, meaning they count toward your weekly total for overtime purposes.³

Breaks also have to stay separate. Your employer cannot combine a rest break with your meal to make one longer break, and cannot let you stack a rest break onto the start or end of your shift so you arrive late or leave early.¹

One 30-Minute Meal Period

A 12-hour shift gets one 30-minute meal period, not two. The length of the shift makes it feel like a second meal should kick in, but BOLI’s chart is clear: shifts in the 10-hour-1-minute to 13-hour-59-minute range earn a single meal break. A second meal period is required only when a shift reaches 14 hours.²

During the meal period, you must be relieved of all duties for the full 30 minutes. Oregon law doesn’t explicitly require your employer to let you leave the premises; the legal standard is relief from work, not freedom to walk out the door. The moment your employer asks you to do anything work-related during that window, whether answering a phone, watching equipment, or staying at your station “just in case,” the meal period becomes a paid one and you are owed wages for the full 30 minutes.¹

A narrow undue hardship exception lets some employers skip the full 30-minute meal period when providing one would genuinely disrupt operations, such as a lone security post or a small continuous-operations crew. Even then, the employer must still provide adequate paid time to eat, rest, and use the restroom, must give all rest breaks required for the shift length, and must provide a specific BOLI notice to the affected worker.¹

When Your Breaks Have to Be Scheduled

Oregon does not let employers lump all of your downtime together. Rest breaks should fall roughly in the middle of each four-hour work segment.¹ On a shift that runs 6:00 a.m. to 6:00 p.m., that means breaks spaced near the midpoints of each segment, not clustered.

The meal period has its own window. For any shift longer than seven hours, the meal has to be taken after you have completed your third hour of work and finished before the start of your sixth hour.¹ On a 6:00 a.m. start, that puts your meal somewhere between 9:00 a.m. and 12:00 p.m. The rule includes “as the nature of the work allows” language that gives employers some flexibility, but not enough to push lunch to 2:00 p.m. on a shift that started at dawn.

Overtime on a 12-Hour Shift

Break pay and overtime pay interact on long shifts, especially if you work several 12-hour days in a row.

For most workers, Oregon follows the standard federal threshold: overtime starts after 40 hours in a workweek. Three 12-hour shifts (36 hours) earn no overtime. Four such shifts (48 hours) produce 8 hours at time-and-a-half.

Manufacturing workers run on a different clock. Oregon requires mills, factories, and manufacturing employers to pay overtime for any hours beyond 10 in a single day, in addition to the weekly 40-hour threshold, with the employer owing whichever calculation produces the greater overtime amount.⁴ On a 12-hour manufacturing shift, the last two hours are automatically overtime regardless of your weekly total.⁵ The same daily overtime rule applies to cannery, drier, and packing plant employees. If you work 12-hour shifts in one of these industries and your employer calculates overtime only by the week, you may be owed back pay.

Who Is Not Covered

Most Oregon employees are covered by these break rules, including healthcare, warehouse, and construction workers who commonly pull 12-hour shifts. The exceptions under OAR 839-020-0050 are narrow:

Workers alone in a retail or service business who are at least 18 and work fewer than five hours in any 16-hour span are not entitled to rest breaks, though the employer must still allow restroom use.¹
Union workers whose collective bargaining agreement specifically addresses meal and rest periods follow the contract terms, which can modify the standard rules.¹
Public school substitute teachers may receive the same breaks as the regular teacher being covered, even when those differ from the standard schedule.¹

If Your Employer Skips Your Breaks

If your employer routinely denies breaks or pressures you to work through them, BOLI handles the complaint. The agency keeps the identity of the person who files confidential. You can start a complaint through BOLI’s online portal, call 971-245-3844, or email help@boli.oregon.gov.⁶

What you can recover depends on the violation. Rest breaks you worked through, and meal periods during which you were kept on duty, are unpaid wages, and you can file a wage claim for them. BOLI may also assess civil penalties against the employer. Hospital workers have a specific statutory penalty of $200 for every missed meal or rest period when a complaint is filed through the Oregon Health Authority.²

Oregon law prohibits retaliation for filing a complaint or asserting your right to breaks. Keep a personal log of missed breaks with dates, shift times, and what happened. It is the most useful evidence you can bring to an investigation.
