5-4/9 roster

A 5-4/9 roster is a compressed work schedule where employees work nine-hour days over a two-week cycle, totalling 80 hours, with one Friday off every other week.

The name describes the structure: five days in week one, four days in week two, nine hours each day throughout. The extra hour worked daily accumulates across the fortnight to cover the full 80 hours, even with the day off. The result is a three-day weekend every second week at no reduction in pay.

How a 5-4/9 roster works in practice

A standard two-week cycle looks like this:

• Week 1: Monday to Friday, nine-hour shifts (45 hours)
• Week 2: Monday to Thursday, nine-hour shifts, plus one eight-hour day, with Friday off (35 + 8 = 80 hours across the full fortnight)

Teams typically stagger which people take their off Friday, so there’s always coverage. The shorter day before the long weekend is sometimes called the flex day.

Where this schedule fits

The 5-4/9 roster is common in government agencies, administrative offices, and professional services where core hours are fixed but some internal flexibility is possible. It works best when the work itself fits comfortably across nine hours and when teams are large enough to split across alternating off-days without leaving gaps.

Benefits of the 5-4/9 roster

The recurring three-day weekend is the clearest draw for team members. It gives people a predictable block of personal time every other week with no change to pay. For employers, total hours stay at 80 per fortnight, so output expectations stay the same. Fewer commutes per cycle is a small but real benefit for anyone with a longer travel time.

Common challenges with the 5-4/9 roster

The main coordination challenge is tracking which team members are off on any given Friday. Without clear visibility, gaps appear. Shift swaps get more complex when people are on different week patterns, since swapping a day in week one doesn’t directly mirror a day in week two. New team members need a clear introduction to the cycle so they always know which week they’re in.
