What Is Nursing Overtime? How the 40-Hour Rule Works
Six 12-hour shifts over two weeks can owe a nurse no overtime, or eight hours of it. The difference is which workweek each shift lands in, and whether interrupted meal breaks and late charting count as work.
Key Takeaways
- Nursing overtime is time a non-exempt nurse works past 40 hours in one workweek. The federal Fair Labor Standards Act requires at least 1.5 times the regular rate for each hour past 40. The regular rate is the hourly figure overtime is calculated from.
- The workweek is a fixed seven-day block the hospital sets. Two workweeks are never averaged.
- Hours worked include meal breaks the nurse was not fully relieved from, required training, late charting, and hours in other departments.
- The regular rate includes shift differentials and bonuses such as attendance and retention bonuses.
- Hourly nurses are owed overtime. A registered nurse on a salary of at least $684 a week may be exempt, per the U.S. Department of Labor.

Nursing overtime is the time a non-exempt nurse works past 40 hours in one workweek. Non-exempt means the law entitles the nurse to overtime pay, and every nurse paid by the hour is non-exempt. Each overtime hour is paid at no less than one and a half times the nurse’s regular rate.
Per Fact Sheet #23, a long day, a weekend or a holiday earns no overtime by itself. What a nurse is owed depends on four things: when the workweek starts, what counts as work, what goes into the regular rate, and whether the nurse is exempt.
How Is the Workweek Defined for Nurse Overtime?
A workweek is a fixed and regularly recurring period of 168 hours, which is seven days in a row. The hospital picks the day and hour it starts. Averaging hours over two or more weeks is not permitted (U.S. Department of Labor).
The no-averaging rule creates overtime nobody planned. Take six 12-hour shifts over two weeks. If the shifts split three and three, the nurse works 36 hours each week and earns no overtime. If the shifts split four and two, the first week has 48 hours and 8 hours of overtime, though the two-week total is the same 72. The start day decides which week a shift lands in. The 12-hour shift guide covers how three-shift and four-shift weeks are usually laid out.
Hospitals have one alternative, often called the 8-and-80 method, which replaces the workweek with a fixed 14-day period. Overtime is then owed for every hour past 8 in a workday and every hour past 80 in the 14 days (29 CFR 778.601). The hospital and the nurse must agree to the method before the work is done. An unwritten agreement needs a record of its terms and the date it was made (29 CFR 516.23). The guide to reducing nurse overtime compares the two methods.
What Counts as Hours Worked for a Nurse?
Hours worked include all the time a nurse must be on duty, plus any time the hospital lets the nurse keep working. The Department of Labor’s hours-worked fact sheet for health care covers the cases that matter on a nursing unit:
- Meal breaks. A meal break is unpaid only if the nurse is completely relieved of duty. When a break is interrupted so often that it mainly serves the hospital, the nurse is paid for the full 30 minutes.
- On-call time. On call at the hospital is work. On call at home with a phone generally is not, but answering calls and coming in does count.
- Training. Required classes and in-services count. A class is unpaid only if it is outside regular hours, truly voluntary, not directly job-related, and involves no productive work.
- Staying late to chart. In one Labor Department example, nurses who stayed late to finish charts were owed time and a half, even without prior authorization.
- Hours in another department. Count every hour the nurse worked for your hospital that week. In a Fact Sheet #54 example, 40 hours as a nurse’s aide plus 16 as a receptionist makes 56 hours, so 16 are overtime. Hours on two units also add up for a per diem nurse who picks up shifts on both.
Every minute of meal break, training and charting time adds to the workweek total. A nurse scheduled for exactly 40 hours goes into overtime with one meal break during which the nurse was not fully relieved of duty. The PRN pool guide covers checking hours before calling in a per diem nurse.
How Do You Calculate Nurse Overtime Pay With a Shift Differential?
The regular rate is the nurse’s total straight-time pay for the workweek, including shift differentials and bonuses such as attendance and retention bonuses, divided by the hours worked (Fact Sheet #54).
Straight-time pay already covers every hour once, overtime hours included. Each overtime hour then adds an overtime premium of half the regular rate, which brings that hour to 1.5 times the rate.
Illustrative round numbers, not market pay data: a nurse earns $40 an hour plus a $4 night differential, and works two day and two night 12-hour shifts in one workweek.
| Step | How it is figured | Amount |
|---|---|---|
| Base pay for all hours | 48 hours times $40 | $1,920 |
| Night differential | 24 hours times $4 | $96 |
| Straight-time pay for the week | $1,920 plus $96 | $2,016 |
| Overtime hours | 48 minus 40 | 8 hours |
| Regular rate | $2,016 divided by 48 hours | $42.00 |
| Overtime premium (half the rate) | 8 hours times $21.00 | $168 |
| Total pay for the week | $2,016 plus $168 | $2,184 |
The total equals 40 hours at $42 plus 8 hours at $63. If payroll figured overtime on the $40 base rate alone, the premium would be 8 times $20, or $160. The nurse would be paid $8 too little that week. Fact Sheet #54 names leaving differentials and bonuses out of the regular rate as a common error in health care.
Are Nurses Exempt From Overtime Pay?
Nurses paid by the hour are owed overtime. A registered nurse can be exempt only by passing two tests in Fact Sheet #17N. The first is a salary of at least $684 a week, the standard salary level as of October 2026. The second is a duties test, which checks that the job needs advanced nursing judgment.
Registered nurses generally meet the duties test. Licensed practical nurses, called licensed vocational nurses in Texas, generally do not. A job title decides nothing. An RN nurse manager paid by the hour is owed overtime.
If your hospital pays a nurse a salary and no overtime, confirm both the weekly salary level and the job-duties test are met. Ask your payroll provider or HR, or call the Department of Labor’s Wage and Hour Division at 1-866-487-9243.
Does Texas Have Its Own Overtime Law for Nurses?
No. Texas has no overtime law for nurses of its own, so the FLSA decides overtime pay. The Texas Minimum Wage Act has no overtime provision, and Labor Code §62.151 excludes anyone the FLSA covers. The Texas nursing overtime compliance guide covers the records to keep.
One federal exception matters to small Texas hospitals. A county or hospital-district hospital is generally a public agency, since the FLSA’s definition includes any political subdivision of a State (29 U.S.C. 203(x)). A public agency may give comp time (paid time off instead of cash) at 1.5 hours for each overtime hour, under an agreement made before the work (29 U.S.C. 207(o)).
Texas does limit whether a hospital can require extra work. Health and Safety Code Chapter 258 stops a hospital from making a nurse keep working past the scheduled shift or come in on an extra day, and the state-by-state guide to mandatory nurse overtime covers the exceptions.
How Does SimpleScheduleAI Count Overtime When It Builds a Schedule?
SimpleScheduleAI is an AI-native nurse scheduling service for critical access hospital scheduling in Texas. AI builds your schedule, our scheduling team checks it, you approve.
The AI nurse scheduling behind each draft counts every nurse’s scheduled hours in each week against the FLSA overtime threshold of 40 hours. A nurse who can cover a shift without going past 40 is used first. When a nurse calls out, the replacement shortlist ranks straight-time candidates above overtime ones, with agency last, as the callout guide explains.
Five limits on that overtime check:
- Scheduled hours, not hours worked. We have no time clock, so a missed meal break or late charting is not in our count.
- Hours, not dollars. We do not calculate the regular rate, differentials or bonuses.
- The 40-hour workweek only. Our schedules do not apply the 8-and-80 method.
- A Monday-to-Sunday week. A payroll week that starts on another day can count a nurse’s hours differently than our schedule does.
- Only the schedules we hold. Hours in a department we do not schedule are not in our count.
One honest limitation: SimpleScheduleAI is not the right fit for a hospital that wants its overtime pay calculated or its payroll audited. Overtime pay stays with your payroll team. See how it works for the steps of each scheduling cycle.
Our Take
The costly overtime mistakes sit in three definitions: which day the workweek starts, whether an interrupted meal break was paid, and whether the night differential reached the overtime rate. A nurse manager does not need to run payroll. The manager does need all three of those definitions for the hospital, because the schedule decides how many hours land in each workweek.
What to Do This Week
- Ask payroll for your workweek start day and time. Check that your template or nurse scheduling software starts the week at the same point.
- Recheck one overtime paycheck. Pick a nurse who worked nights and overtime in the same week, and redo the regular rate with the differential included.
- Split last month’s overtime into scheduled and unscheduled. Ask payroll for the hours report by nurse and by workweek. Overtime on the posted schedule is scheduled. The rest is unscheduled: late charting, missed meals, callout cover, and hours in another department. The two totals answer the CFO who asks where the overtime came from.
- Look at how meal breaks are deducted. If the deduction is automatic, find out how a nurse reports a missed or interrupted break.
- Confirm which overtime method each nurse is on. For any nurse on 8-and-80, find the agreement or its record, dated before the work started.
A schedule built around the 40-hour line
AI builds your schedule, our scheduling team checks it, you approve. Onboarding takes 3 to 5 business days and your first schedule lands inside two weeks.
See how it works →Frequently Asked Questions
Q: Do paid vacation or sick hours count toward the 40?
Not under the FLSA. Overtime is owed on hours actually worked, and Fact Sheet #53 says the law does not require pay for holidays, vacation, sick or personal time at all.
Q: Can a nurse agree to give up overtime pay?
No. Fact Sheet #23 says the overtime requirement cannot be waived by agreement. An agreement to count only 40 hours a week as work also fails.
Q: When does overtime have to be paid?
Fact Sheet #23 says overtime is normally due on the regular payday for the pay period in which it was earned.
