Panama Shift Schedule: 2-2-3 Crew Rotation Explained

The Panama name describes more than a row of work days. It is commonly used for a four-crew continuous-coverage arrangement built around the 2-2-3 sequence.

For one person, that sequence is:

2 work → 2 off → 3 work → 2 off → 2 work → 3 off

Two crews can be assigned to days and nights while two corresponding crews are off, then the positions alternate according to the employer’s roster.

One crew’s 14-day calendar

This example starts on Monday. It deliberately says “Work” because the work/off pattern does not establish whether your crew is currently on days or nights.

Week	Mon	Tue	Wed	Thu	Fri	Sat	Sun
1	Work	Work	Off	Off	Work	Work	Work
2	Off	Off	Work	Work	Off	Off	Off

Another crew can follow the inverse of these work/off positions. Day and night crews are then staggered so the operation remains covered.

Why some rosters say 28 days

The personal work/off sequence returns after 14 days. But that does not necessarily return you to the same shift type. If an employer changes a crew from days to nights after one fortnight and back after the next, the complete assignment takes 28 days.

Other employers keep crews on the same shift for months. This is why copying a generic “Panama calendar” without checking the day/night rule can create a schedule that looks correct for two weeks and fails afterward.

Panama, Pitman, and 2-2-3 naming

These names frequently point to the same base sequence. They are not reliable evidence of one universal day/night policy.

• Use the 2-2-3 guide for the basic work/off math.
• Use the Pitman guide to distinguish fixed and rotating variants.
• Use this page when you are trying to understand how your crew fits into continuous day/night coverage.

Working hours

Seven 12-hour shifts equal 84 scheduled hours per 14-day work/off cycle, averaging 42 hours per seven days. In the Monday-starting example, five shifts land in week one and two in week two.

Pay periods, overtime thresholds, and shift premiums are separate workplace or legal questions.

Advantages and disadvantages

Possible advantages

• Every second weekend can contain a three-day break.
• No work stretch exceeds three scheduled days.
• Four staggered crews can cover both 12-hour shifts continuously.
• The base pattern is predictable after one correct setup.

Possible disadvantages

• Five 12-hour shifts can land inside one calendar week.
• A rotating version requires repeated day/night adjustment.
• Two employers may use “Panama” for different rotation intervals.
• Overtime or crew swaps can obscure the underlying sequence.

Where it is used

Four-crew 12-hour systems suit workplaces requiring uninterrupted coverage, such as manufacturing, processing, utilities, security, healthcare, and emergency operations. That does not mean every workplace in those sectors uses the same Panama implementation.

What to copy from your real roster

Record your crew identifier, one confirmed cycle-start date, the work/off sequence, exact shift times, and the rule that changes days to nights. Add exceptions separately so they do not move the repeating base calendar.

The CCOHS shiftwork guidance recommends predictable advance schedules and highlights recovery, workload, shift length, and rotation direction as separate safety considerations.
