The 2-2-3 Work Schedule: A Complete Guide

The first time I looked at a 2-2-3 schedule, I counted the hours wrong. I saw the neat two-on, two-off, three-on rhythm, added up an average of 42 hours a week, and assumed the overtime would wash out. It does not. The weeks are uneven, one is 48 hours, and that 48-hour week generates real overtime every other week, whether you planned for it or not.

The 2-2-3 is still a genuinely good schedule for round-the-clock work, as long as you see that overtime coming. This guide covers what a 2-2-3 schedule is, how the four-team rotation works, exactly how the hours and overtime break down, the state rules that make 12-hour shifts expensive, how it compares to schedules like the DuPont, and how to set it up without a payroll surprise.

The 2-2-3, better known as the Panama schedule, is one of the most common ways to cover a 24/7 operation. If you run a business that never closes, whether a care facility, a manufacturing line, a security operation, or a call center, some version of this pattern is probably already on your radar. Its appeal is real: continuous coverage with only four teams, every other weekend off, and a rhythm employees can actually memorize.

I built FirstHR to give small businesses a solid HR foundation. On top of it, a rotating 12-hour schedule only works when the coverage and the overtime math are both handled correctly, which is what this guide is for. This article is general information, not legal advice, so confirm specifics with counsel for your situation.

What Is a 2-2-3 Work Schedule?

A 2-2-3 work schedule is a rotating shift pattern that provides continuous, around-the-clock coverage using 12-hour shifts and four teams. Employees work two days on, two days off, and three days on, then the pattern inverts the following week to two off, two on, three off. The rhythm repeats every 14 days, and the defining feature is that it staffs a 24/7 operation while giving each team a three-day weekend every other week.

The name comes directly from the pattern: two days on, two days off, three days on. You will also see it written as 2/2/3, 223, or spelled out as "2 on 2 off 3 on 3 off," and all of these mean the same schedule.

The most common name is the Panama schedule, a nickname that reportedly traces to the Panama Canal Zone, where continuous round-the-clock operations required this kind of staffing, though the exact origin story is debated. The Pitman schedule is another name for essentially the same pattern.

What makes the 2-2-3 a rotating schedule, rather than a fixed one, is that teams do not work the same days every week. The two-week rhythm shifts across the calendar, so weekends, nights, and holidays get distributed fairly across all four teams over the cycle. Nobody is permanently stuck with every weekend or every night.

That built-in fairness is a big part of why the schedule is popular for the demanding, always-on work it is used for. To see how it holds together, you have to look at exactly how the four teams interlock.

How the 2-2-3 Rotation Works

The four teams in a 2-2-3 are arranged so that two are always working, one on days and one on nights, while the other two are off. This is what delivers unbroken 24/7 coverage with only four teams instead of the larger number a naive approach would require. The mechanics are easiest to see laid out across the full 14-day cycle for all four teams at once.

Read across the grid and you will see that each team follows the same two-on, two-off, three-on rhythm, just offset from the others so coverage never breaks. Two teams handle the day shift, typically something like 6 AM to 6 PM, and two handle the night shift, 6 PM to 6 AM. That offset is what makes the whole design work.

The rotation adds one more layer over the longer term. In a common version of the full Panama rotation, the teams assigned to days and the teams assigned to nights swap after 28 days, so that over time everyone shares both the day and night burden. The complete cycle then repeats every 56 days. There is no official definition, and some operations swap every 14 days instead; the swap date is yours to set.

Some operations skip this day-to-night swap and keep teams permanently on days or nights, which is the fixed Pitman variant. Whether or not the teams flip, the underlying 2-2-3 rhythm and the four-team coverage stay the same.

Pitman Schedule Example

Here is that fixed version laid out. Teams A and B hold the day shift, teams C and D hold nights, and nobody moves at day 28. The rhythm below is the same one in the grid above, so the hours and the overtime do not change either.

The tradeoff is straightforward. Nobody flips between days and nights, which is easier on sleep, but the night teams stay on nights indefinitely. If you pay a shift differential, it sits on the same two teams every cycle instead of moving around, and filling permanent night crews is harder than filling a rotation everyone shares.

Weekly Hours and the Overtime Built In

Here is the part that catches employers: the 2-2-3 does not produce 40-hour weeks. It produces uneven weeks that average to 42 hours, and that average hides a swing that has real overtime consequences. Over the 14-day cycle, each team works seven 12-hour shifts, which is 84 hours across two weeks, or 42 per week on average. But the two weeks are not equal.

The critical point is that federal overtime is calculated per workweek and cannot be averaged across two weeks. What matters is not the 42-hour average but the heavy week's 48 hours: non-exempt employees, the ones entitled to overtime pay, are owed the 8 hours over 40 at time and a half.

A common misconception is that the 42-hour average lets you figure overtime on a two-week basis. It does not. The Fair Labor Standards Act (FLSA) requires it weekly, so the 48-hour week always triggers 8 hours of overtime.

This built-in overtime is not necessarily a problem; many employees value the reliable extra earnings, and it is predictable enough to budget for cleanly. The mistake is not knowing it is there. An employer who models the 2-2-3 as a flat 42-hour average and forgets the weekly calculation will under-budget labor costs on every heavy week. Getting the number right up front, before rollout, is what protects your margins.

The 36 and 48 split depends on where your workweek starts. Under 29 CFR 778.105, a workweek is any fixed, regularly recurring period of seven consecutive days, and it may begin on any day. Five of the seven possible start days split the rotation into the three-shift and four-shift weeks shown in the table above.

Put the grid above on a calendar where day 1 is a Monday, so the three-shift blocks fall Friday through Sunday. A Sunday workweek start gives you that three-and-four split, but a Monday start turns the weeks into 60 and 24 hours.

With a Monday start, the heavy week carries 20 overtime hours rather than 8, about 520 a year per employee, so settle the workweek start before you model the cost.

Healthcare has one special case worth knowing. Hospitals and residential care facilities can use a federal exception known as the "8 and 80" rule. With a prior agreement from the affected employees, they pay overtime for hours worked over 8 in a day and over 80 in a fixed 14-day period, instead of using the standard weekly calculation.

That healthcare option raises the bill on a 2-2-3 rather than lowering it. Each 12-hour shift carries 4 hours of daily overtime, so seven shifts produce 28 overtime hours per period, against the 8 the weekly rule produces with the usual three-and-four split.

State Overtime Rules and 12-Hour Shifts

The federal weekly overtime is only part of the compliance picture, and for a 12-hour schedule the state rules are often the bigger cost. Several states require daily overtime, meaning overtime is owed for hours worked beyond a daily threshold regardless of the weekly total. On a 12-hour shift, that daily threshold matters enormously, because every single shift can trigger daily overtime.

California is the example most likely to surprise employers. Non-exempt employees there are owed time and a half for hours beyond 8 in a single day, up to 12 hours, and double time for any hours beyond 12. On a 12-hour shift, hours 9 through 12 are daily overtime on every shift, regardless of the weekly total.

An Alternative Workweek Schedule adopted by a two-thirds employee vote is not the escape hatch it is often described as. According to the California Division of Labor Standards Enforcement, an approved alternative workweek covers a regularly scheduled day of no more than 10 hours, so a 12-hour day still carries daily overtime.

The one exception is health care. Only health care employers under Wage Orders 4 and 5 (two of California's wage and hour rules for specific industries and occupations) may schedule an alternative workweek day of more than 10 and up to 12 hours without daily overtime, and double time still applies past 12. Everyone else pays 4 hours of daily overtime on every 12-hour shift.

Beyond California, the daily rules are narrower than they look. Alaska requires overtime after 8 hours in a day, but only at employers with four or more employees. Nevada requires it after 8 hours only for employees paid less than 1.5 times the state minimum rate.

Colorado requires overtime after 40 hours in a week, 12 hours in a day, or 12 consecutive hours, whichever calculation pays more, so a shift there earns daily overtime only once it runs past 12 hours. Alaska and Nevada can add cost to a 12-hour schedule that the federal weekly rule alone would not, and the rules change, so model the full labor cost in every state where your employees work.

Pros and Cons of a 2-2-3 Schedule

Setting the compliance mechanics aside, the 2-2-3 has genuine strengths and real drawbacks as a way of organizing shift work. Whether it fits depends on the nature of the operation, the tolerance of your team for 12-hour shifts, and how you weigh continuous coverage against the fatigue that long shifts create. Here is an honest accounting.

The advantages are what make the 2-2-3 so widely adopted for 24/7 work. Four teams cover every hour, never more than three consecutive shifts are worked, and the every-other-weekend three-day break is a real quality-of-life benefit that helps recruiting and retention. The fair distribution of days, nights, and weekends across all teams heads off the resentment that fixed-shift systems often breed. For the right operation, it is an elegant solution to a genuinely hard staffing problem.

The drawbacks center on the 12-hour shift itself. According to a NIOSH science bulletin (2023), researchers estimate that close to 1 in 8 workplace injuries may relate to fatigue. NIOSH names scheduling practices such as night shifts and extended hours among the work factors that interfere with sleep. It also notes that fatigued workers may take longer to react and may take more risks that lead to injury or error.

The day-to-night rotation compounds that by disrupting sleep and health, and the built-in overtime, while predictable, is a real cost. None of this rules out the 2-2-3, but it is why the schedule demands careful fatigue management and honest cost modeling rather than casual adoption.

Which Industries Use the 2-2-3 Schedule

The 2-2-3 shows up wherever an operation genuinely cannot stop. The common thread across the industries that use it is a need for continuous, around-the-clock staffing where coverage gaps are unacceptable. If the work has to happen at 3 AM on a Sunday just as much as at 3 PM on a Tuesday, the 2-2-3 is one of the standard answers.

Healthcare is a frequent adopter, particularly nursing floors, emergency departments, and long-term care, where patients need round-the-clock attention. Public safety and security, including dispatch, emergency communications, and guard services, rely on it for the same reason. Continuous manufacturing and utilities use it to keep production lines and infrastructure running without interruption. And 24/7 call centers and support operations use it to maintain coverage across all hours and time zones.

These industries also share the stakes of getting coverage wrong. A gap in hospital nursing coverage or utility monitoring is not a minor inconvenience; it can be dangerous. That is why these sectors accept the complexity and cost of a rotating 12-hour schedule: the alternative, a gap in coverage, is far worse. For operations without that hard 24/7 requirement, the 2-2-3 is usually more schedule than the work actually needs.

2-2-3 Schedule Variations

The 2-2-3 is one of a family of rotating 12-hour shift patterns, and it helps to know the close relatives, because the names get used loosely and the differences are real. Most share the four-team, 12-hour structure and differ mainly in the order of work blocks and how quickly teams rotate between days and nights.

The most important distinctions are between the 2-2-3 and its two closest relatives. The Pitman is simply a fixed 2-2-3 where teams stay on days or nights instead of rotating, which some employees prefer because it avoids the circadian disruption of switching.

The DuPont, covered in more detail below, uses longer work blocks and a longer rest period on a 28-day cycle. The DDNNOO and 3-2-2 patterns rearrange the same building blocks into different rhythms with shorter or differently ordered work stretches.

You will also see this rotation written as 2-3-2. Count the same 14-day cycle from a different starting point and the blocks read two shifts on, three days off, two shifts on, which is the identical Panama pattern under another label. The name is not universal, though. Some references use 2-3-2 for a compressed plan that packs a fortnight of hours into seven longer shifts, so confirm which pattern the other person means.

A note on the "3-2-2" specifically: the term is ambiguous. As a shift schedule, it is a close relative of the 2-2-3 with a reordered block pattern. But "3-2-2" is also used for a hybrid office schedule of three days in the office, two remote, and two off, which is an entirely different concept unrelated to shift work. When you see "3-2-2," check which meaning is intended, because the two have nothing in common beyond the numbers.

2-2-3 vs DuPont Schedule

The 2-2-3 and the DuPont are the two most common four-team, 12-hour rotations, and choosing between them is a frequent question for operations setting up 24/7 coverage. Both average 42 hours per week and cover every hour with four teams. The difference is in the rhythm of work and rest, and that difference matters for fatigue and morale.

The rhythm also changes the overtime math. The DuPont's longer blocks can put up to 72 hours into one workweek, so its weekly overtime swings more with the workweek start than the 2-2-3's does. Run the same week-by-week cost model on it before you choose.

The core tradeoff is frequent short breaks versus one long break. The 2-2-3 never works more than three consecutive shifts and hands out a three-day weekend every two weeks, which keeps cumulative fatigue lower across the cycle. The DuPont concentrates the rest into a full seven-day break but requires up to four consecutive 12-hour shifts to earn it, which is harder on the later days of the block. Neither is universally better.

The practical guidance most operations follow is to choose based on where fatigue does the most damage. If the work involves high moment-to-moment cognitive load, like emergency nursing or dispatch, the 2-2-3's shorter work blocks reduce the risk of errors piling up on a fourth consecutive night. If the work is steadier and employees value a long stretch off, the DuPont's seven-day break can be the bigger draw.

Running a 2-2-3 With a Small Team

The catch with the 2-2-3 on a small team is that a true version requires four teams, and that is a real constraint. If you cannot staff four balanced teams, you cannot run a genuine 2-2-3 as designed. This is the point most guides gloss over, and it is the first thing to confront before adopting the schedule with limited headcount.

That does not mean a smaller operation has no options, but it does mean being realistic. With enough people to form four teams, even if each team is small, the 2-2-3 works as intended.

With fewer people than that, you are looking at modified patterns: fewer teams with more overtime, a simpler two-team day-and-night split without the full rotation, or bringing in part-time or on-call staff to fill the gaps. Each of these trades some of the 2-2-3's benefits for feasibility at a smaller scale.

The realistic question for a smaller operation is whether you genuinely need continuous 24/7 coverage or whether your real need is extended-hours coverage that a simpler schedule can meet at lower cost and complexity.

A compressed schedule like the 9/80, or a straightforward two-shift arrangement, may serve extended hours without the four-team requirement and built-in overtime of a full 2-2-3. Being honest about the actual coverage requirement, rather than adopting a 2-2-3 because it is well known, saves smaller operations real money.

How to Set Up a 2-2-3 Schedule

Implementing a 2-2-3 correctly is a sequence, and the order matters because the coverage and compliance groundwork has to come before the schedule goes live. Rushing to announce the rotation before the team count and overtime cost are worked out is how operations end up understaffed or over budget. Here is the sequence that produces a practical, compliant 2-2-3.

The two steps most often underestimated are calculating the team count and modeling the state overtime cost, and those are precisely the two that determine whether the schedule is feasible and affordable. Everything else is execution: documentation, communication, tracking, and fatigue management. For the documentation step, the acknowledgment below records each employee's team, shift times, and workweek start, and has them confirm the hours that start produces.

The thread running through every part of a 2-2-3 is that accurate time tracking against the correct workweek is what makes the whole thing work. The uneven 36 and 48-hour weeks, the built-in overtime, the daily overtime in certain states, the four-team assignments: all of it depends on recording 12-hour shifts correctly and calculating against the right thresholds.

A system that assigns employees to teams, shows each person their own rotation, and calculates overtime correctly turns the 2-2-3 from a compliance and coverage headache into a schedule that runs itself. If you are weighing the schedule now, start with the cost model above: set your workweek start, fill in the four teams, and price the heavy weeks before you announce the rotation.
