The Panama (2-2-3) Shift Pattern Explained
A slower, longer-cycling rota than 4 on 4 off — same amount of rest, spread across shorter working blocks that land on different days each cycle.
What The Pattern Actually Is
Panama is built from a repeating 14-day cadence, per shift type: 2 days on, 2 off, 3 on, 2 off, 2 on, 3 off — then it starts again. Written as a string it looks like WWOOWWWOOWWOOO, where each letter is one day. Count it up and across that 14-day half-cycle you work 7 days and rest 7 — exactly half and half, just arranged in uneven blocks instead of one flat 4-and-4 split.
That 14-day cadence is only half the story. Panama is typically run across a 4-team rotation providing round-the-clock cover, with each team also rotating between day and night shifts. Once both the day-shift half and the night-shift half of the rotation are counted, the pattern completes a full 28-day cycle before an officer is back exactly where they started — working the same shift type, on the same day of the cycle, as four weeks earlier.
Compare that to 4 on 4 off, which resets every 8 days. Panama takes more than three times as long to complete a full loop, which is precisely what makes it feel different to work even though the underlying ratio of work to rest is identical.
Where Does The Name Come From?
Panama isn't a police invention, and it isn't unique to UK forces. This exact 2-2-3 cadence — or close variants of it — shows up under the same name across a wide range of industries that need continuous, round-the-clock cover: manufacturing plants, hospitals, control rooms, and other emergency services all use versions of it. It reads as an industry-standard naming convention for this style of slow-rotation pattern, adopted by policing rather than created by it.
We haven't been able to verify a definitive origin story for why it's called "Panama" specifically, and we'd rather be upfront about that than invent one. If you've heard a credible explanation, treat it as folklore until it's backed by something more solid than a rota-planning forum post.
Why Forces Use It
The appeal of Panama is stability of shift type. Because the cycle is slow — 28 days rather than 8 — an officer changes from days to nights (or back) far less often than on faster-rotating patterns. Over a full cycle, there are only two shift-type changes, compared to the more frequent switching that patterns like Continental require. Fewer changeovers generally means less disruption to sleep and body clock, which is a big part of why slow-rotation patterns like Panama are favoured in fatigue-conscious rota design.
The trade-off is predictability of rest. On 4 on 4 off, your rest days shift forward by a fixed, easy-to-track amount, and the block length never varies — it's always 4 and 4. On Panama, a working block might be 2 days or it might be 3, and which one you're in at any given point depends on where you are in the 14-day cycle. That makes it noticeably harder to glance at a calendar and know, six weeks out, exactly which days you'll be off.
The Honest Pros And Cons
What Works
- Working blocks top out at 3 days, not 4 — many officers find that easier to push through, especially on 12-hour shifts.
- Only two shift-type changes per full 28-day cycle, versus far more frequent switching on faster-rotating patterns.
- Total rest is unchanged from 4 on 4 off — 7 rest days for every 7 worked, averaged over the fortnight.
What's Harder
- Uneven block lengths (2s and 3s) mean your rest days land on different days of the week each cycle — much less "same day off every week" than a fixed pattern.
- A 28-day full cycle is a lot to hold in your head when planning childcare, appointments, or a social life months in advance.
- The gap between the shortest and longest working stretch (2 days versus 3) can make some weeks feel front-loaded and others feel light, even though the average is level.
Maximising Leave On Panama
The classic annual leave trick — book your entire working block off, and it merges with the rest days sitting either side into one long, unbroken break — still works on Panama. But because Panama's working blocks are only 2 or 3 days long, not a flat 4, the merged break you get is shorter than what 4 on 4 off produces from the same trick with its 12-day maximum stretch.
Concretely: if you book off the 3-day working block, it merges with the rest days immediately before it and the rest days immediately after it into one continuous break. Do the same with a 2-day block and you get a shorter merged break again. Exactly how long each of those breaks comes out to depends on precisely where in the 14-day cycle that block falls — the rest periods either side of a 2-day block and a 3-day block aren't the same length, so there's no single number that applies to every block on the pattern.
Rather than us guessing at a figure that won't be accurate for your specific team's rota position, plug your actual pattern in and see the real merged length for each block.
What Panama Means For Your Pay
Because Panama splits its working blocks across both day and night shifts over the full 28-day cycle, the mix of unsocial-hours and night-rate pay you earn can look quite different from an officer on a pattern that stays on one shift type for longer stretches. Night shifts and weekend working typically attract allowance uplifts on top of basic pay, and how much of your working time falls into those categories depends on exactly where in the cycle your team sits.

Frequently Asked Questions
What is the Panama shift pattern?
Panama is a slow-rotating shift pattern built from a 14-day cadence per shift type: 2 days on, 2 off, 3 on, 2 off, 2 on, then 3 off, before repeating. Run across a 4-team rotation covering both days and nights, it becomes a full 28-day cycle. Across each 14-day half, officers work 7 days and rest 7 — the same ratio as 4 on 4 off, just arranged differently.
Why is it called Panama?
The name isn't specific to policing — 2-2-3-style slow-rotation patterns turn up under this name across many 24/7 industries (manufacturing, healthcare, control rooms, emergency services) as a standard way of labelling this cadence. We haven't found a definitive, verifiable origin for the name, so we'd rather say that honestly than invent a story.
How many hours a week does Panama average?
Averaged over the full 14-day cycle, Panama works out to 7 working days per fortnight — the same average as 4 on 4 off. On 12-hour shifts that's an average of 42 hours a week, though any single week within the cycle can look quite different (as few as 2 shifts, as many as 5) because the blocks aren't evenly sized.
Is Panama better than 4 on 4 off?
Neither is objectively better — they trade off different things. Panama's blocks are shorter (2 or 3 days rather than a flat 4), which many officers find less fatiguing to work through, and it takes longer to fully rotate. But because the blocks are uneven, your rest days land on different days of the week each cycle, which some officers find harder to plan around than 4 on 4 off's fixed, predictable rhythm.
Does Panama give you more rest days than 4 on 4 off?
No — total rest days per fortnight are identical: 7 on, 7 off either way. Panama doesn't give you more time off, it just distributes the same amount of rest across shorter, uneven working blocks instead of one flat 4-day block.
