The Panama shift pattern (2-2-3): how it works and who it suits

The Panama pattern, also written 2-2-3, is the rota that gives people every other weekend off while covering the site 24 hours a day. It is a favourite in control rooms, emergency services and manufacturing for one reason: nobody ever works more than three days in a row. Here is how the cycle works and where it beats 4 on 4 off.

What 2-2-3 means

Read the numbers as blocks of work and rest over two weeks:

• Week one: work 2, off 2, work 3
• Week two: off 2, work 2, off 3

That is a 14-day cycle. Line it up against the days of the week and something useful appears: the three-day block lands on a weekend one fortnight and off it the next, so every second weekend is a full three days off. Shifts are 12 hours, typically 07:00 to 19:00 and 19:00 to 07:00.

The hours

The totals are almost identical to 4 on 4 off, which is the point worth making to anyone comparing the two: they cost the same in hours. What differs is the shape of the week, not the pay.

Slow rotation or fast rotation

Panama comes in two flavours. In a slow rotation a team stays on days for several weeks, then switches to nights. In a fast rotation the day and night blocks alternate within the cycle. Slow is kinder to sleep because the body settles into one rhythm; fast spreads the unpopular nights around more evenly. There is no universally right answer, so ask the team which they would rather live with.

Panama versus 4 on 4 off

• Days in a row: Panama caps you at three, 4 on 4 off makes you do four. Three is easier on most people.
• Weekends: Panama guarantees every other weekend off. On 4 on 4 off, weekends drift and are never predictable.
• Blocks of rest: 4 on 4 off gives a clean four days off every time. Panama's rest comes in a two, then a two, then a three, which is choppier.
• Simplicity: 4 on 4 off is easier to picture. Panama's 14-day cycle takes longer to learn.

If predictable weekends matter to your team, Panama wins. If long unbroken breaks matter more, 4 on 4 off does.

Who it suits

Panama fits round-the-clock operations where the work is demanding enough that four days straight would be too much: emergency services, security control rooms, power and utilities, and manufacturing lines that run continuously. Like 4 on 4 off, it needs four teams to cover 24/7.

Why the fortnight breaks a spreadsheet

A 14-day cycle fits a seven-day spreadsheet even worse than an eight-day one does. The pattern only repeats every two weeks, so a weekly grid shows you half a cycle and hides the rest. Working out who is owed which weekend, and totalling the hours across four teams and two shift types, is exactly the manual counting that goes wrong the month you are busiest.

Running Panama in InShift

Set up your day and night shift types once, assign the four teams to the 2-2-3 cycle, and InShift keeps the count: it adds up hours as the rota is worked and exports a timesheet to Excel for any period, so a fortnightly cycle and a monthly pay run stop fighting each other. Everyone sees their own shifts and their next weekend off in the app, and swaps go through without a phone tree.
