How Many Employees Does One 24/7 Post Need in Poland?
Holding one position every hour of 2026 in Poland takes 8,766 staffed hours. One full-time employee is genuinely available for about 1,722 of them, so the post needs 5.09 employees, which is 6 whole people.
One ring per person, one year each
Each ring is one employee's year, broken wherever they are on holiday, on leave, or off sick. No single ring closes, which is the whole problem: one person cannot hold a post that never stops.
Stack 6 of them and the picture closes. Trace any line out from the center and it crosses at least one solid arc, so every hour of 2026 has somebody on it. That is the relief factor, drawn rather than asserted.
Where the number comes from
- 1
Staffing one position 168 hours a week comes to 8,766 hours across the year.
- 2
Poland has 261 weekdays in the year, the starting point for one employee.
- 3
Take out 8 public holidays that fall on a weekday, 20 days of statutory paid leave, 14.8 days of average sickness absence, and 3 days of training: 45.8 days lost.
- 4
That leaves 215.2 working days per employee, and at a 40-hour week that is 8 hours a day, so 1,722 available hours a year.
- 5
8,766 coverage hours divided by 1,722 available hours is a relief factor of 5.09, so the post needs 6 people.
| Weekdays in the year | 261 |
| Public holidays on a weekday | −8 |
| Statutory paid annual leave | −20 |
| Average sickness absence | −14.8 |
| Training and onboarding (assumed) | −3 |
| Working days available | 215.2 |
| At 8 hours a day | 1,722 hours |
Paid public holidays are a statutory entitlement in Poland, so they sit on top of annual leave and are deducted separately here.
The training allowance of 3 days is a planning assumption rather than a sourced statistic, and it is deliberately low. Every other figure on this page carries a source. If your operation runs heavy certification cycles, raise it and the relief factor rises with it.
What the usual rule of thumb gets wrong here
The common shortcut is to divide coverage hours by contracted hours and add a quarter for absence. In Poland that gives 5.25 against a derived answer of 5.09, so the shortcut is high by 3.1 percent. A flat buffer travels badly because the things it stands in for, statutory leave and the length of the contracted week, are set nationally.
Nobody ever away. Not a real answer.

Other coverage shapes
The same availability figure answers any coverage window. Only the hours the post must be staffed change.
| Coverage | Hours a week | Relief factor | People |
|---|---|---|---|
| Round the clock, every day | 168 | 5.09 | 6 |
| Round the clock, weekdays only | 120 | 3.64 | 4 |
| Two shifts, every day | 112 | 3.39 | 4 |
| Extended day, weekdays only | 60 | 1.82 | 2 |
If your contract is more generous
20 days is the statutory floor in Poland, and most employers sit above it. Every extra week of leave is another week the post has to be covered by somebody else.
| Annual leave | Relief factor | People per post |
|---|---|---|
| 20 daysstatutory floor | 5.09 | 6 |
| 25 days | 5.21 | 6 |
| 28 days | 5.29 | 6 |
| 30 days | 5.34 | 6 |
| 33 days | 5.42 | 6 |
The inputs, and what they do not say
How the leave figure is defined
Stated in days in the Labour Code (Art. 154 par. 1), and those days are working days: Art. 154(2) par. 1 says leave is granted only on days that are working days for the employee under their own schedule, one leave day equalling 8 hours. No conversion was needed. Public holidays are excluded: they are non-working days under Art. 151(9) par. 1 and the separate Act on non-working days, so they never consume leave entitlement.
Why the contracted week is not the legal maximum
This page divides by a 40-hour week, the typical full-time contract in Poland, not by the 40-hour statutory figure. The two match here, so the distinction makes no difference to the answer.
What these figures cannot be used for
Not a ranking. The sickness figure here comes from a national statistical source, while other countries in this library use the OECD labour force survey. Those systems define absence differently, and self-reported survey figures undercount short spells that administrative records capture. Each number is the best available answer for planning inside its own country, and the gap between any two of them is partly a gap between statistical methods rather than between workforces.
A relief factor also says nothing about whether a roster is legal or humane. It sets how many people the post needs across a year; it does not check rest periods between shifts, consecutive nights, or weekend distribution. Those constraints decide whether the pattern you build on top of this headcount is one anybody can actually work.
Research notes on Poland
LEAVE, AND THE MOST LIKELY MISREAD. The statutory minimum is 20 working days, but that only applies below 10 years of employment. At 10 years or more it is 26 days (Art. 154 par. 1). Art. 155 counts completed education toward that threshold, and higher education alone counts as 8 years, so a graduate reaches 26 days after roughly 2 years of actual work. For any experienced or degree-holding Polish workforce, 26 is the realistic planning figure, not 20. I returned 20 because the field asks for the statutory minimum.
PUBLIC HOLIDAYS ARE ON TOP, NOT INSIDE. Poland has 14 statutory public holidays as of 2025 (24 December was added by the 6 December 2024 amendment, up from 13). They sit outside the 20/26 days. On top of that, Art. 130 par. 2 of the Labour Code reduces the monthly working-time norm by 8 hours for each public holiday falling on a day other than Sunday, so a holiday cuts required hours rather than leave.
HOURS. The 40 hours is an average, not a hard weekly cap: Art. 129 par. 1 sets 8 hours per day and an average of 40 hours in an average five-day week over a reference period of up to 4 months, extendable to 12 months under Art. 129 par. 2. The real ceiling including overtime is an average of 48 hours per week (Art. 131 par. 1). Equivalent-working-time systems permit 12 hour days (and up to 16 or 24 in specific cases) as long as the average holds, which matters for shift planning.
COLLECTIVE HOURS. There is no meaningful gap between statutory and collectively agreed hours in Poland. Collective bargaining coverage is low and concentrated at company level, and agreements do not systematically shorten the week below 40. Eurostat confirms the practical week is not shorter: full-time employees usually worked 40.4 hours in 2025 and 40.3 in 2024, slightly above 40 because usual hours include habitual overtime. So 40 is the contracted week, and anything a planner sees above 40 is overtime, not a longer contract.
SICKNESS: THESE ARE CALENDAR DAYS. 14.8 is calendar days per insured person, not working days. Derivation: ZUS recorded 241,997.3 thousand days of own-illness absence among ZUS-insured persons in 2025, divided by 16,302.8 thousand persons insured with ZUS at December 2025, giving 14.84. Polish sick notes run over continuous calendar periods and sickness benefit is due for every day of incapacity including non-working days (Art. 11(4) of the sickness and maternity benefits act), which is why the count is calendar-based. The working-day equivalent on a 5-day week is about 10.6 days (14.84 x 5/7). Do not add 14.8 straight onto the 20 working days of leave; that would overstate sickness shrinkage by around 40 percent.
SICKNESS DENOMINATOR CAVEAT. ZUS's insured population is not exclusively employees; it includes contractors on umowa zlecenie and self-employed people with voluntary sickness cover. Employees alone accounted for 169,859.8 thousand of the 2025 own-illness days (70.2 percent of the total), but ZUS does not publish a matching count of insured employees in these reports, so an employees-only rate cannot be computed exactly from the same register. It would land near 13 to 14 calendar days. Cross-check on the figure I did return: ZUS's own per-health-insured-person rates by voivodeship in 2025 range from 12.85 days (Mazowieckie) to 17.25 days (Lodzkie), so a national 14.8 is consistent with ZUS's own methodology. The figure covers own illness only; care for a child or other family member added roughly a further 12.5 million days and is excluded here.

Art. 11 par. 4: sickness benefit is due for every day of incapacity for work, not excluding non-working days. This establishes that ZUS absence days are counted in calendar days.
Common questions
- How many people does one 24/7 position need in Poland?
- 6 people. One position staffed every hour of the year is 8,766 hours, and one full-time employee in Poland is actually available for about 1,722 of them once 45.8 days of holidays, leave, sickness and training come out. That is a relief factor of 5.09, which rounds up to 6 whole people.
- What is a relief factor?
- The number of employees needed to keep one position filled continuously, once the days nobody works are taken out. It is coverage hours divided by the hours one employee is genuinely available. In Poland that is 8,766 divided by 1,722, or 5.09. A factor below the headcount you actually employ means the post runs on overtime.
- Why is a flat 25 percent absence buffer not enough for Poland?
- Because it overshoots here. A raw hours calculation gives 4.2 employees, and adding a flat quarter takes that to 5.25, against a derived answer of 5.09. That is 3.1 percent too high, because the rule of thumb assumes more leave and sickness than Poland actually loses.
- Does the statutory leave minimum reflect what employers actually give in Poland?
- It is a floor, not a norm. This page computes on the statutory minimum of 20 working days because that is the figure the law fixes and a source can be attached to. Most employers sit above it, and the sensitivity table on this page shows what the relief factor becomes at more generous entitlements, so a planner can find their own contract rather than taking the floor as the answer.
