Shift Work Laws: Compliance Guide for Small Businesses

Your closer just finished at midnight. You need someone to open at 6am. You're wondering: can I schedule the same person? Is that even legal?

It's a question every shift-based business owner runs into. The honest answer: it depends on where you operate. Federal law is largely silent on rest between shifts, but several states and cities aren't. And the penalties for missing those rules aren't small. Here's what you need to know.

The short answer on hours between shifts

There's no federal minimum for hours between shifts. But state and local laws fill that gap, and they vary a lot.

• Federal law: No minimum rest period required between shifts
• Oregon: 10 hours required for covered retail, hospitality, and food service employers
• San Francisco: Covered formula retail employers must provide advance notice and pay predictability premiums for schedule changes
• New York City: Fast food workers have clopening protections; utility safety workers have advance notice and no on-call call-in protections
• Seattle: Covered employers must pay time-and-a-half for hours worked in closing and opening shifts less than 10 hours apart
• 12- and 14-hour shifts: Legal federally for most adult workers, but overtime still applies
• Clopening: Legal federally, restricted or penalized in some cities

If you operate in multiple locations, check each city and state separately. The rules don't travel with you.

Does federal law require time between shifts?

Federal law sets no minimum number of hours between shifts. The Fair Labor Standards Act governs overtime pay, minimum wage, and recordkeeping, but it says nothing about how long employees must rest before coming back in.

What federal law does require:

• Overtime pay after 40 hours in a workweek (time-and-a-half), per the DOL overtime rules
• Compensable time for all hours the employer requires or permits employees to work, including most required meetings, training, prep, and waiting time — though whether specific activities count depends on the facts
• Recordkeeping for at least 3 years for payroll records, and at least 2 years for time cards and work schedules

Because federal law is silent on rest periods, state and local governments have stepped in with their own rules. Some have nothing at all. Others have penalties with real teeth. That's why "check your state" isn't a cop-out. It's the actual answer.

Which states require minimum time between shifts?

Many states don't set a general minimum rest period between shifts, but some state and local laws do for certain industries or covered employers. A handful of jurisdictions, mostly in the west and northeast, have passed predictive scheduling laws that directly regulate shift gaps, especially for food service, retail, and hospitality workers.

Oregon

Oregon has a statewide predictive scheduling law for certain large employers. For retail, hospitality, and food service employers with 500 or more employees globally, workers generally cannot be scheduled within the first 10 hours after a prior shift unless they request or consent. If an employee agrees to work during that window, the employer must pay time-and-a-half for every hour worked during that rest period, even if the employee volunteered for it.

San Francisco

San Francisco's formula retail scheduling law, Article 42, requires covered employers to provide two weeks' advance notice of schedules. Employer-initiated schedule changes can trigger predictability pay and on-call pay obligations. If you operate a covered formula retail location in San Francisco, check the current code carefully — the requirements go beyond just shift timing.

New York City

NYC's Fair Work Week law has two separate regimes. Fast food employers must pay a premium for clopening shifts and must offer additional hours to existing staff before hiring new employees. Utility safety employers face advance notice requirements and restrictions on on-call and call-in shifts. These are distinct rules — don't apply one to the other.

Seattle

Under Seattle's Secure Scheduling Ordinance, covered employers must pay time-and-a-half for hours worked in closing and opening shifts that are less than 10 hours apart. Employees may also decline hours that weren't on the originally posted schedule without penalty.

What if your state isn't on this list?

Federal law is your floor, which means no mandatory rest period. But legal and smart aren't the same thing. OSHA and NIOSH warn that long, extended, irregular, and rotating shifts can increase fatigue and injury risk. Chronic clopening also drives turnover faster than almost anything else. More on both below.

Is clopening legal?

Federally, yes. There's no law preventing you from scheduling someone to close at midnight and open at 6am. It happens constantly in restaurants, retail, and hospitality, and in most of the country, it's perfectly legal.

In cities with predictive scheduling laws, though, the calculus changes. In Seattle, employers must pay a time-and-a-half premium for clopening hours less than 10 hours apart. In NYC, fast food employers pay a clopening premium and San Francisco's formula retail law triggers predictability pay for certain schedule changes. Schedule a clopening in those cities without following the rules and you're not just creating a tired employee. You're creating a wage claim.

Even where it's fully legal, clopening carries real costs. OSHA warns that extended and irregular shifts can increase fatigue-related safety risks and workers' comp exposure. And employees who regularly clopen don't stay long. If you want to avoid clopening shifts altogether, the fix usually lives in your scheduling process, not your team's availability.

How long can a shift legally be?

For most adult workers, federal law sets no maximum shift length. You could schedule a 16-hour shift and face no federal violation, as long as you're paying correctly.

That surprises a lot of owners. But the absence of a federal cap doesn't mean anything goes. Overtime, OSHA, and state-specific industry rules all come into play.

Are 12-hour shifts legal?

Yes, in most states. Twelve-hour shifts are standard in healthcare, manufacturing, and hospitality. You'll owe overtime if the employee crosses 40 hours for the week, or 8 hours in a single day if you're operating in California, Alaska, or Nevada. Daily overtime changes the math significantly, especially for employees picking up extra shifts.

Are 14-hour shifts legal?

Also yes, federally, for most workers. Industry-specific rules carve out exceptions. Truckers face DOT hour limits, and California has special overtime rules for some healthcare employees that differ from the standard schedule. For most small business workers, a 14-hour shift is legal as long as overtime is calculated correctly. Legal doesn't mean no obligation. It just means no cap.

OSHA and long shifts

OSHA's General Duty Clause requires employers to provide a workplace free from recognized serious hazards. OSHA warns that long and irregular shifts can create fatigue-related safety risks that fall under this obligation. Long shifts are legal, but they can create liability if something goes wrong and a pattern of unsafe scheduling contributed to it.

State overtime rules shift workers need to know

Overtime rules and shift scheduling are directly connected. Get the scheduling right but miscalculate overtime and you're still on the hook. Here's a quick reference for states where daily overtime applies, not just weekly.

California: Daily overtime after 8 hours (double time after 12 hours) | 40 hours weekly Alaska: Daily overtime after 8 hours | 40 hours weekly Nevada: Daily overtime after 8 hours if earning less than 1.5x minimum wage | 40 hours weekly Colorado: Daily overtime after 12 hours | 40 hours weekly All other states: No daily threshold | 40 hours weekly

The four overtime mistakes that cost small businesses most:

• Unauthorized overtime: Your employee stays late without asking. You still owe overtime. Per the DOL, overtime must be paid when the employer requires or permits it — "I didn't approve it" isn't a defense.
• Training and meeting time: Mandatory meetings and most employer-required training count as hours worked. Optional off-hours training may not, depending on the circumstances.
• Tipped employee calculations: For tipped employees under the FLSA, overtime is based on the employee's regular rate, which includes the direct cash wage plus the tip credit the employer claims. Don't calculate overtime from the $2.13 tipped base wage alone.
• Misclassified salaried workers: Salary alone doesn't make someone exempt from overtime. Exemption depends on both salary level and duties — and the federal salary threshold can change.

How to build schedules that stay compliant

Compliance doesn't have to be complicated. Follow these steps and you'll catch most issues before they become expensive.

1. Know your local laws. Federal law is the starting point, not the finish line. Check your state labor laws before you build your next schedule, especially if you operate in Oregon, California, Washington, New York, Illinois, or Pennsylvania.
2. Write a rest policy. Even where it's not legally required, a written policy on minimum hours between shifts sets clear expectations and gives you something to point to if a dispute comes up.
3. Track every minute. Pre-shift prep, waiting for deliveries, mandatory meetings — all potentially compensable. If your time tracking relies on employees remembering to clock in and out accurately, you have a gap.
4. Post schedules early. In some predictive scheduling jurisdictions, employer-initiated late schedule changes trigger premium or predictability pay. Even where it's not required, two weeks out is the standard that reduces no-shows and last-minute scrambles.
5. Use a scheduling tool that knows your rules. Homebase offers overtime alerts, labor-law settings, and compliance configuration tools that help you catch issues before they become payroll problems. Build the schedule, not the liability.

Frequently asked questions

How many hours between shifts is legally required?

Federal law has no minimum hours between shifts requirement. Many states follow federal law, meaning there's no mandatory rest period. Exceptions include Oregon (10 hours for covered employers) and certain local laws like Seattle's Secure Scheduling Ordinance. Always check your specific state and city — rules vary by industry, employer size, and jurisdiction.

Is clopening illegal?

Clopening is legal under federal law. However, cities including Seattle, San Francisco, and New York City restrict or penalize clopening under local scheduling laws. In Seattle, covered employers must pay time-and-a-half for clopening hours less than 10 hours apart. In NYC, fast food employers must pay a clopening premium. San Francisco's formula retail law triggers predictability pay for certain schedule changes.

What's the longest shift you can legally work?

Federal law doesn't cap shift length for most adult workers. A 12-hour or 16-hour shift is federally legal as long as overtime is paid correctly. Some industries have their own limits — California has special overtime rules for some healthcare employees, and truckers face DOT hour restrictions. For most small business roles, there's no legal maximum on shift length.

Do you have to have 8 hours between shifts?

Not under federal law, and not in most states. Oregon requires 10 hours between shifts for covered employers, with a premium pay obligation if that window isn't honored. Seattle requires time-and-a-half for clopening hours under 10 hours apart. Outside of specific state or local laws, there's no universal requirement for 8 hours between shifts.

The bottom line

The honest answer to "how many hours between shifts is legal?" is: it depends on where you operate. Federal law gives you a lot of flexibility. State and local laws can take some of it back, with real financial penalties attached. The safest move is knowing your jurisdiction's rules, building them into your scheduling process, and using tools that catch issues before they become violations.
