4 on 4 off roster

A 4 on 4 off roster is a shift schedule where employees work four consecutive days, then have four consecutive days off, repeating in a continuous cycle.

The cycle runs over eight days, which means it doesn’t align with the standard calendar week. Each rotation, a person’s working stretch starts one day later than the previous one. Someone who works Monday through Thursday one cycle will begin their next stretch on a Friday. Over time, this naturally distributes weekend shifts across the team without any manual adjustment.

How a 4 on 4 off roster works in practice

Most operations running this pattern use at least two teams on opposite cycles to maintain continuous coverage. For 24-hour operations, four teams is a common setup, with each group rotating through the available time slots so there’s always someone on. Teams working 12-hour shifts log 48 hours across their four working days, followed by four full days off.

The pattern is predictable by design. Team members can see their working days months ahead, which makes it easier to plan around appointments, childcare, or travel. Managers get a stable framework that doesn’t need rebuilding each week.

Common challenges

Four consecutive shifts can be physically demanding, particularly in roles involving manual work or long hours. Fatigue tends to build toward the end of a working stretch, which is worth factoring in when assigning tasks on day four.

Public holidays fall inside different people’s working stretches at different points in the cycle. Tracking who worked which holidays and applying any compensation consistently requires reliable records. Without them, small discrepancies accumulate.

Swaps and last-minute absences are harder to coordinate when the team is split across multiple cycle phases. At any given moment, some people are on their third working day, some are mid-rest, and some are just starting. Finding an available replacement means knowing exactly where everyone sits in the rotation.

How Zelos helps

Zelos works alongside a fixed 4 on 4 off base schedule. When someone needs to swap a shift or pick up an extra one outside their usual cycle, Zelos lets team members handle that through a simple signup flow. Managers can post open slots and let people claim them directly, rather than coordinating each change by hand.
