The 8/80 overtime rule for hospitals, explained

The 8/80 overtime rule lets a hospital measure overtime over a fixed 14 day period instead of a 7 day week. The hospital pays time and a half for every hour over 8 in a workday and every hour over 80 in the period, whichever adds up to more. It comes from section 7(j) of the Fair Labor Standards Act, and it is one of the few places federal law cares about hours in a single day.

It sounds like a way to save money, and for some schedules it is. For the typical ICU or med surg unit running 12 hour shifts, it usually does the opposite. Here is how it works, where it helps, and what a nurse manager should check before assuming which system their unit is on.

What the 8/80 rule is and who can use it

Normally the FLSA counts overtime by the workweek: any hours over 40 in a fixed 7 day week get time and a half, and the law does not care how many hours land on one day. Section 7(j) carves out an alternative for two kinds of employers: hospitals, and institutions primarily engaged in caring for sick, aged or mentally ill people who live on site. The Department of Labor's own examples of the second group include nursing facilities, assisted living and intermediate care facilities, though whether a particular facility qualifies depends on its facts.

The details live in the regulation at 29 CFR 778.601. In short, the hospital and the employee agree ahead of time that a period of 14 consecutive days replaces the 7 day week for overtime. The 14 day period can start at any hour of any day, and once it is set it is meant to stay put.

A few practical limits come from the Department of Labor's Field Operations Handbook and Fact Sheet #54:

• It is not only for clinical staff. The handbook lists back office roles like payroll and engineering, with limits for contractors doing non medical work and for people who spend a large share of their time on work outside the hospital.
• It does not apply to an employee who, during a 14 day period, is employed in more than one hospital. That matters for agency staff.
• The hospital can use 8/80 for some employees and the 40 hour week for others. Fact Sheet #54 adds that it cannot use both for the same person.

How overtime is counted under 8/80

There are two tests, and both apply in every period.

1. Daily: every hour worked over 8 in a workday is overtime, whether or not the person reaches 80 hours in the period.
2. Period: every hour over 80 in the 14 days is overtime, whether or not any single day went over 8.

You do not pay both on the same hours. The regulation lets the premium already paid for daily overtime count toward the overtime owed for hours over 80. In practice that means overtime hours for the period are whichever number is bigger: total daily overtime hours, or total hours minus 80. Washington State's labor department says it exactly that way in its own guidance.

That last point catches people. The Department of Labor's handbook gives the example of an employee who works two 8 hour shifts inside one workday: the second shift is all overtime. A 1975 opinion letter looked at a hospital whose workday started just after midnight. An employee worked a day shift, then started a night shift at 11:30 p.m. That last half hour landed in the same workday, making 8.5 hours, so half an hour was overtime. The same boundary can split a 7p to 7a night shift across two workdays. Where your hospital set the start of its period quietly decides how night shifts and double backs get counted.

A worked example: 8 hour shifts vs 12 hour shifts

Take two nurses on the same unit over one 14 day period. Assume, for the arithmetic, that no 8 hour shift runs late and that each 12 hour shift falls inside a single 24 hour workday. A night shift that crosses the workday boundary can count differently, as above.

Nurse A works 8 hour shifts and picked up an extra shift in week one: six shifts in week one, four in week two, 80 hours total.

• Under the 40 hour week, week one has 48 hours, so 8 hours of overtime. Week two has 32 hours and none.
• Under 8/80, no day went over 8 and the period hit exactly 80. Zero overtime.

Nurse B works 12 hour shifts, three each week, 72 hours total.

• Under the 40 hour week, each week is 36 hours. Zero overtime.
• Under 8/80, each shift has 4 hours over 8. Six shifts make 24 hours of daily overtime, even though the period is well under 80.

These are our own illustrations, worked from the rule's text, not examples published by the Department of Labor. But the pattern is the point: 8/80 rewards uneven weeks of 8 hour shifts and punishes long shifts. That is why 12 hour units, where full time usually means three 12 hour shifts for a 36 hour week, are so often paid overtime on the standard 40 hour week, and why a manager inheriting a unit should not assume which system it is on. Ask payroll, and look at a timecard.

The agreement has to come first

8/80 needs an agreement or understanding between the hospital and the employee before the work is performed. Three details are worth knowing:

• It does not have to be in writing. If it is not written, the hospital has to keep a record summarizing its terms, when it started and how long it lasts. That requirement is in the recordkeeping rules at 29 CFR 516.23.
• It can be presumed from notice. The Department of Labor's handbook says agreement may be presumed when an employee accepts pay after being told the hospital uses 8/80, by a posted notice or a payroll insert.
• Without it, the default applies. Without a prior agreement, section 7(j) does not apply, and overtime is owed under the normal 40 hour week rule.

Blogs often say the 8/80 agreement must be signed. The federal regulation says otherwise, although your hospital's policy or a union contract may require more.

No switching back and forth

The regulation is blunt: changing from the 14 day period to the workweek and back again to take advantage of lower overtime is not allowed. Fact Sheet #54 adds that the start of the period can change only if the change is meant to be permanent and not to evade overtime, and that for the changeover the hospital has to figure pay both ways and pay whichever is better for each employee. A hospital can run different groups of employees on different systems, but one employee lives on one system.

For a manager, this mostly means you cannot fix a bad week by asking payroll to count it the other way. Plan the schedule around the system your unit is actually on.

The regular rate still includes differentials and bonuses

Overtime under 8/80 is time and a half of the regular rate, not of base pay. Under 8/80 the regular rate is figured over the 14 day period, and it includes nearly everything paid for the work:

• Shift differentials for nights and evenings go into the regular rate, and none of that premium counts as overtime pay. Weekend premiums below time and a half go in too. A weekend or holiday premium of time and a half or more is treated differently and can count toward overtime.
• Bonuses that were promised in advance, such as attendance, retention and extra shift bonuses, go into the regular rate. A discretionary bonus is left out only if the hospital decides both whether to pay it and how much at or near the end of the period, with no prior promise. A few other payments, like true gifts and some referral bonuses, can also be left out.

The Department of Labor's Fact Sheet #54, written for the health care industry, walks through examples of each, including nurses with a night differential and staff at an intermediate care facility with an attendance bonus. If your unit runs incentive pay for extra shifts, it is worth knowing that those incentives raise the overtime rate too.

State law can add to it

Federal law sets the floor. Some states add their own rules, and the stricter rule wins. As of October 2026, a few examples from each state's own labor department:

• California: the 14 day period is allowed for hospitals and residential care under Wage Order 5, but the state labor commissioner's office says daily overtime after 8 hours and double time after 12 hours still apply.
• Colorado: the state's wage order lets a hospital or nursing home agree with individual employees to pay overtime under the federal 8/80 rule instead of Colorado's own overtime rule.
• Alaska: hospital employees who provide medical services are exempt from the state's overtime law, which leaves federal law in charge.
• Washington: state guidance recognizes 8/80 and counts whichever overtime total is greater.
• Texas: there is no state overtime law for employees covered by the FLSA, so the federal rules, including 8/80, govern.

Every state is different, and these change. If your hospital operates somewhere else, your state labor department's website is the place to check.

What a nurse manager should actually do

You almost certainly do not choose the overtime system. HR and payroll do, usually for the whole hospital or a whole job class. What you control is the schedule, and the schedule is where overtime gets made. A short checklist:

1. Find out which system your unit uses, in writing, from payroll.
2. If you are on 8/80, watch for two shifts landing in one 24 hour workday, including a night shift followed by an early return. Each one creates daily overtime.
3. If you are on the 40 hour week, the weekly total is what matters. A sixth shift in one week is overtime even if the next week is light.
4. Remember that differentials and incentive bonuses raise the overtime rate, so an incentive shift that also triggers overtime costs more than it looks.
5. Track overtime by person, not just in total, so you can see who carries the extra hours before the period closes.

If your unit already runs its schedule in Adelo Workforce, the manager side includes analytics for hours and overtime, so you can see a problem while there is still time to change the schedule.

Questions people ask

Is the 8/80 rule legal in California?

Yes. California's Wage Order 5 allows hospitals and residential care facilities to use a 14 day period. The state labor commissioner's office says California's own daily overtime after 8 hours and double time after 12 hours still apply, so the state rules usually decide the outcome.

Does the 8/80 agreement have to be in writing?

No. Federal rules require an agreement or understanding before the work is done, but not a written one. If it is not written, the hospital has to keep a record of its terms, and the Department of Labor can presume agreement when an employee accepts pay after being notified.

Can a hospital use 8/80 for some employees and the 40 hour week for others?

Yes. A hospital can choose either system for any group of employees. It cannot use both for the same employee, and it cannot switch someone back and forth to lower overtime.

Does the 8/80 rule work with 12 hour shifts?

It can apply, but it rarely makes sense. Every hour past 8 in a workday is overtime under 8/80, so a 12 hour shift that falls inside one workday carries 4 hours of daily overtime, even if the person works only 72 hours in the period. A night shift can split across two workdays depending on when the hospital starts its period.

Does 8/80 apply to agency nurses?

The Department of Labor's handbook treats temporary staff as employed jointly by the agency and the hospital. It will not object to the hospital using 8/80 for a 14 day period in which the nurse works only at that hospital, if they agreed to it before the work. It does not apply if the nurse works at more than one hospital during the same period.
