The numbers behind each pattern

• A 2-2-3 cycle has 7 twelve-hour shifts in 14 days, or 84 hours, which averages 42 hours per week.
• Every four-crew 24/7 pattern averages 42 hours per week because 168 coverage hours divided by 4 crews equals 42 hours.
• Under FLSA 8/80, overtime is owed for hours over 8 in a workday and hours over 80 in the fixed 14-day period.Source: U.S. Code, 29 U.S.C. § 207(j)
• The FLSA workweek is a fixed, recurring 168-hour period, and changing it cannot be designed to evade overtime requirements.Source: 29 CFR § 778.105
• A 2012 Health Affairs study reported that nurses working shifts of 10 hours or longer were up to 2.5 times more likely to report burnout, job dissatisfaction, and intent to leave.Source: Health Affairs, Stimpfel, Sloane, and Aiken
• A Health Affairs study of hospital nurse work hours reported that error risk rose sharply when shifts exceeded about 12.5 hours.Source: PubMed, Rogers et al., The Working Hours Of Hospital Staff Nurses And Patient Safety

Choose the grid by its tradeoff

The first decision is whether you need a closed 24/7 crew rotation or a fixed-shift staffing model. A four-crew rotation fills one day post and one night post by design, but it averages 42 hours per week. Fixed 3 x 12 keeps a nurse at 36 hours, but the schedule itself does not guarantee that every slot is covered.

That 42-hour number is arithmetic, not a benefit of one clever pattern. If four crews cover 168 hours of continuous service, each crew absorbs 42 hours on average. A fifth crew lowers the average, while a fixed-12 model handles relief and open shifts through headcount, float coverage, or another staffing plan.

2-2-3, Panama, and Pitman use the same 14-day skeleton

Vendor sources use these names loosely. The honest version is one 14-day skeleton: work 2, off 2, work 3, off 2, work 2, off 3. Pitman often means fixed days or fixed nights. Panama often means the crews swap day and night after two weeks. Those labels are not consistent enough to justify separate schedules.

This is the classic four-crew, 24/7 grid. Crews A and C cover days. Crews B and D cover nights. Every column has one day crew and one night crew.

Cycle length is 14 days. Each crew works 7 shifts, or 84 hours, for a 42-hour average week. Four crews cover 24/7. The grid gives every other weekend off, with the off weekend forming a three-day block. The fixed form avoids day-to-night flipping. The rotating form shares day and night exposure, but the two-week swap gives staff a short reset window.

DuPont gives a full week off, with a hard middle

DuPont is a 28-day cycle. One crew works 4 nights, has 3 days off, works 3 days, takes 1 day off, works 3 nights, takes 3 days off, works 4 days, then gets 7 days off. Three other crews run the same cycle offset by 7 days.

Each crew works 14 shifts, or 168 hours, per cycle. That is 42 hours per week on average, and four crews are needed for 24/7 coverage. The seven-day break is attractive for retention. The cost is four consecutive nights, a single day to turn from days to nights, and a 72-hour week in the second block. This is an industrial pattern that fits nursing poorly unless the unit has a strong reason to accept that fatigue profile.

4-on / 4-off is simple, but the calendar drifts

The fixed form repeats every 8 days. The rotating form below repeats the day and night assignment across a 16-day crew cycle. Four crews are offset by four days, so one day crew and one night crew cover each calendar day.

Each crew works 4 shifts in 8 days, or 48 hours per cycle, which averages 42 hours per week. Four crews cover 24/7. Because 8 does not divide evenly into 7, the pattern walks across the calendar. Weekends drift, and a nurse may work Saturday without working Sunday. The four-day recovery block is real, but four consecutive 12-hour shifts are also a real fatigue concern.

Fixed 12s are a staffing model, not a closed rotation

Most US hospitals and SNFs use fixed day or fixed night assignments rather than a closed crew rotation. The nurse has a fixed shift and FTE. The exact weekdays are assigned, self-scheduled, or balanced around a weekend policy. That means the grid below is a copyable example, not a universal cycle.

The common 3 x 12 version averages 36 hours per week and creates no designed-in overtime under a 40-hour workweek. A fourth shift creates a 48-hour week and 8 hours above 40. There is no fixed number of crews for 24/7 because this is a headcount model. You hire enough day staff and night staff to cover every slot, then fill absences with relief, float, incentive pay, or agency coverage.

Its strength is stability. Nurses do not flip between day and night, and the employee can have real control over weekdays. Its weakness is that coverage is not guaranteed by the pattern. Weekend fairness must come from policy, and an open night shift remains open until someone accepts it.

The 8/80 calculation is the trap to check first

Under FLSA 8/80, hospitals and residential care establishments may use a fixed, recurring 14-day period instead of the normal seven-day workweek, but only with a prior agreement or understanding with the affected employee. The rule pays overtime above 8 hours in a workday and above 80 hours in the 14-day period. You cannot use both systems for the same employee.

The 4 hours over 80 in the 8/80 period are credited against the 28 hours of daily overtime. They do not make the total 32. This is why 8/80 is usually the most expensive option for a 12-hour nursing rotation, not an overtime shortcut.

The workweek boundary matters. Federal regulation lets an employer set the boundary on any day and at any hour, but a later change must be permanent and cannot be designed to evade overtime requirements. Set the boundary deliberately, document it, and ask counsel before changing an existing setup to lower an overtime bill. California has a separate health-care alternative workweek election for qualifying schedules. Check your state's rule instead of copying a hospital practice into an SNF.

Use the grid with fatigue and coverage checks

12-hour shifts reduce handoffs, but a longer shift is not automatically safer. The Health Affairs research cited above found higher burnout and dissatisfaction at 10 hours or longer, and another study reported sharply higher error risk once shifts ran past about 12.5 hours. Treat a three-consecutive-12s limit as a facility practice, not a universal legal rule.

Before publishing any pattern, check the longest block, the day-to-night transition, and the first assignment after a short recovery gap. Also check what happens when one person calls out. A closed rotation can still need relief coverage for PTO, training, vacancies, and unexpected census changes. A fixed schedule can look calm while leaving a night slot uncovered.

For a nursing facility, keep scheduled hours separate from reporting hours. PBJ records paid work by calendar day, not the label on the schedule. An overnight shift crosses midnight, and CMS requires a meal-break deduction from a full shift. Schedule design and payroll reporting answer different questions.

Where a copied schedule fails

• Do not publish separate Panama and Pitman grids as if the names describe separate mathematics. The sources use them inconsistently.
• Do not describe 8/80 as a way to avoid overtime on 12-hour shifts. Seven 12-hour shifts create 28 daily overtime hours under that method.
• Do not move the workweek boundary just to reduce an existing overtime bill. The regulation cautions against changes designed to evade overtime requirements.
• Do not turn a three-consecutive-12s cap into a legal claim. It is common facility practice, not a universal rule confirmed by the research.
• Do not treat a fixed 3 x 12 grid as 24/7 coverage. It assigns an employee's hours, while the facility still has to staff every day and night slot.
