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
| Measure | Panama 2-2-3, 12-hour shifts |
|---|---|
| Working days per 14-day cycle | 7 |
| Hours per cycle | 84 |
| Average per week | 42 hours |
| Hours per year | about 2,190 |
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.
