The 4 On 4 Off Shift Pattern: Rotation, Examples & Template

The 4 on 4 off shift pattern covers continuous operations with teams working four consecutive 12-hour shifts followed by four days off, repeating every 8 days. With two day teams and two night teams it staffs a 24/7 operation and averages 42 hours a week per person.

Try the rotation

Pick a start date to map the rotation onto real weeks. Team A starts the cycle on day 1; the other teams are staggered so cover never drops.

How the rotation works

The rhythm could not be simpler: work four, rest four, forever. Most sites run it with fixed crews — teams A and B alternate the day shift while C and D alternate nights — though rotating variants (4 days on, 4 off, 4 nights on, 4 off) are common where nobody wants to own the night shift permanently.

Because the cycle is 8 days, your work days drift through the calendar: you work every day of the week and you get every day of the week off, in turn. Over any 8-week span it evens out exactly — but it never aligns with a Monday-to-Friday world, which is both the pattern's gift (quiet weekday time off) and its tax (working some of every weekend rhythm).

Four days off in a row, every single cycle, is the headline. No other mainstream pattern delivers a 4-day break that frequently.

Who uses it

  • UK emergency services & control rooms — one of Britain's most widely used 12-hour rosters
  • Security & corrections — continuous posts with fixed day/night crews
  • Rail, ports & logistics — 24/7 infrastructure with predictable crewing
  • Manufacturing & process industries — continuous lines that want minimal handovers
  • Healthcare support & care homes — 24/7 cover where 4-day recovery blocks help retention

Pros & Cons

Pros

  • Four consecutive days off every cycle — half your life is genuinely off-duty
  • Dead simple to understand, administer and memorise
  • Only two handovers a day with 12-hour shifts
  • Fixed-crew version gives stable sleep schedules
  • Rolling pattern shares weekends and weekdays perfectly evenly over time

Cons

  • Four consecutive 12-hour shifts — fatigue peaks on day four
  • The roster never settles into the weekly calendar; regular weekly commitments are hard
  • You work roughly half of all weekends (rolling evenly through them)
  • 48-hour work weeks alternate with 36-hour ones; payroll must handle the swing
  • In the fixed version, night crews permanently carry the night burden

Frequently asked questions

How many hours a week is 4 on 4 off?
An average of 42 hours on 12-hour shifts: 48-hour weeks (four shifts) alternating with 36-hour weeks (three shifts) as the 8-day cycle rolls through the calendar.
Is 4 on 4 off a good shift pattern?
People who like it really like it: half of all days are full days off, in 4-day blocks. The trade-offs are four consecutive 12-hour shifts and a pattern that never matches the Monday-to-Friday week.
How many days a year do you work on 4 on 4 off?
About 183 shifts a year (half of 365), against roughly 230 for a standard 5-day week — though each shift is 12 hours rather than 8.
Does 4 on 4 off include nights?
Usually, yes. In the fixed version two of the four teams work permanent nights. In rotating versions each team alternates blocks of day shifts and night shifts.
How many staff does 4 on 4 off need?
Four teams. If a shift needs 6 people on duty, the roster needs 24 — plus relief cover for leave and sickness.
