How many hours does each person work on a 4-person 24/7 schedule?

A 24/7 operation requires 168 hours of coverage per week, so 4 people average 42 hours each. That is 2 hours over a standard 40-hour week, and this built-in overtime is standard practice in 24/7 industries. The classic 4-team rotations such as 2-2-3, Pitman, and DuPont are all designed around this 42-hour average.

What is the best shift pattern for 4 people covering 24/7?

With 12-hour shifts the week breaks into 14 slots, and the main candidates are 2-2-3 (never more than 3 shifts in a row, every other weekend fully off), Pitman (a 3-day weekend every other week on a 14-day cycle), and DuPont (a full 7 days off each 28-day cycle, offset by one roughly 72-hour week). If 8-hour shifts are required, Continental rotates 4 teams through days, swings, and nights at the same 42-hour weekly average. The right choice depends on whether the crew values short runs, predictable weekends, or the long break.

Should a 4-person 24/7 roster use 12-hour or 8-hour shifts?

A week of 24/7 coverage divides into 14 twelve-hour slots or 21 eight-hour slots, and either way 4 people average 42 hours each. Most 4-person crews run 12-hour shifts because the established 4-team patterns, including 2-2-3, Pitman, and DuPont, are built on them. Continental is the standard 8-hour rotation when longer shifts are not an option.

Is a 4-person 24/7 schedule legal under EU working time rules?

Yes on hours: the EU Working Time Directive caps average weekly hours at 48, and 4 people covering 168 hours average 42 each, well inside the cap. The directive also requires 11 hours of daily rest between shifts, which rules out quick turnarounds and constrains how absences can be backfilled on a 12-hour roster.

What happens when one of the 4 people is absent?

There is no spare in a 4-person 24/7 roster, so every absence converts one-for-one into extra hours for the remaining three, who already average 42 per week. A fifth person drops the average to 33.6 hours and creates cover for planned leave. For a roster that absorbs sickness and vacation without overtime, plan on 6 people.

Staffing math

What is the best 24/7 shift pattern for 4 people?

Four people at 42 hours each is the classic small-team 24/7 staffing level, and the pattern choice matters more than the headcount math.

The short answer

4 people can cover 24/7 with one person on duty by splitting 168 weekly coverage hours into an average of 42 hours per person, so roughly 2 hours of built-in weekly overtime each.

Coverage window: 24/7
Hours to staff / week: 168
Shift length: 12h
Shifts to fill / week: 14
Hours each: 42h
With absence buffer: 6 people

Why the math lands there

There are 168 hours in a week, and a 24/7 post has to fill every one of them. Split across 4 people, that is 42 hours each, 2 hours over a standard 40-hour week. That extra is built-in overtime, standard practice in 24/7 industries rather than a planning error. The week divides into 14 twelve-hour slots or 21 eight-hour slots, and the classic 4-team rotations are all engineered to land each person on the same 42-hour average.

Four people is the staffing level the entire 4-team pattern canon was built for. 2-2-3, Pitman, DuPont, and Continental all solve the same 168-hour problem; they differ in what the 42 hours feel like. Pick 2-2-3 to never work more than 3 shifts in a row, Pitman for a predictable 3-day weekend every other week, DuPont for a full week off each cycle, or Continental if 8-hour shifts are non-negotiable.

The arithmetic holds only while all four people show up. There is no spare in this roster, so every sick day and vacation week converts one-for-one into overtime for the other three. A fifth person drops the average to 33.6 hours each, and planning for absence points to 6 people for zero-overtime resilience. Most small 24/7 operations accept the risk and run with 4, which is exactly why the pattern decision deserves the attention.

124 hours a day times 7 days a week = 168 coverage hours to staff every week.
2168 hours divided into 12-hour shifts = 14 shifts to fill every week.
3168 hours divided by 4 people = an average of 42 hours per person per week, or 3.5 shifts each.
4Nobody works every scheduled week. With a typical 20 to 25 percent allowance for leave, sickness, and training, plan for 6 people to keep the roster from running on overtime.

Headcount options, side by side

The same 168 weekly coverage hours spread over different team sizes. Average weekly hours per person is the number that decides whether a roster is sustainable, legal, and affordable.

People	Hours / person / week	Shifts / person / week	Verdict
3	56	4.7	Over legal limits in most countries
4this page	42	3.5	Built-in overtime
5	33.6	2.8	Standard workload
6	28	2.3	Slack for absence
7	24	2	Slack for absence
8	21	1.8	Slack for absence

The absence buffer above assumes 20 to 25 percent of paid time goes to leave, sickness, and training. Your own rate decides the real number, which you can work out with our shrinkage calculator.

Rotations that make this work

These are proven patterns for this configuration, each with a full interactive calendar and staffing breakdown.

2-2-3 schedule (Panama)

Four teams on 12-hour shifts over a 28-day cycle, averaging 42 hours per week, with never more than 3 shifts in a row and every other weekend fully off. For a 4-person crew with no swap slack, the capped runs are the safety feature.

Pitman schedule

The same 42-hour average on a shorter 14-day cycle, with every other weekend a full 3-day weekend. Its predictability suits a 4-person roster where trades are hard to arrange.

DuPont schedule

Averages 42 hours per week across a 28-day cycle and delivers a full 7 days off, paid for with one roughly 72-hour week. With 4 people there is no relief for that heavy week, so confirm the crew wants the trade before committing.

Continental schedule

The 8-hour answer to the same 168-hour problem: 4 teams rotate fast through days, swings, and nights on a 28-day cycle, still averaging 42 hours. Expect 21 slots per week to fill instead of 14.

What the arithmetic does not tell you

Every 4-team pattern lands on the same 42-hour average, so the spreadsheet cannot pick the rotation for you. The differences are structural. DuPont buys its full 7 days off with one roughly 72-hour week that all four people have to be genuinely willing to work, while 2-2-3 caps runs at 3 consecutive shifts but takes a 28-day cycle to balance out. With only three possible swap partners, a pattern the crew resents cannot be traded around, so choose it with the crew, not for them.

Budget the overtime as a certainty, not a contingency. At this staffing level, covering an absence is never a question of who is free, it is a question of which of the other three gives up a scheduled day off. A two-week vacation means three people carry the full 168 hours between them until it ends. If that is not tolerable, the real decision is a fifth person at 33.6 hours each, not a cleverer rotation of the four you have.

Under the EU Working Time Directive, the 42-hour average sits inside the 48-hour weekly cap, but the required 11 hours of daily rest between shifts constrains how you patch holes. Someone coming off a night shift cannot legally backfill the next day shift, so absence cover on a 12-hour roster is tighter than the raw hours suggest.

Once the headcount is settled, the daily work is keeping the roster fair and covered as people swap, call in sick, and take leave. That is the part Soon automates, from constraint-aware auto-scheduling to leave management.
