Reasonable Overtime Test

Your employer can require 38 hours a week plus reasonable additional hours — no more. This tests the extra hours you're being asked to work against all ten factors in s62(3) of the Fair Work Act, and tells you whether you can lawfully refuse.

Last verified: 19 July 2026

Full-time employees have a 38-hour cap. Part-time and casual employees are capped at the lesser of 38 and their agreed ordinary hours.

Include all hours you're required or requested to work, plus any authorised leave (s62(4) counts leave toward the weekly total).

A standing every-week requirement is much harder for an employer to justify than an occasional surge.

Fatigue, driving home after long shifts, safety-critical work, insufficient break between shifts, or a documented health condition.

School pick-ups, childcare hours, caring for a family member, or a second job you'd have to give up.

A real business need — a breakdown, a genuine peak, someone off sick. Chronic understaffing or poor rostering is not the same thing.

This is one of the heaviest factors. Unpaid extra hours are much harder to justify as reasonable.

Giving notice of your intention to refuse is expressly relevant under s62(3)(f) and strengthens your position. In writing is best.

Some industries — agriculture in harvest, emergency services — have accepted long-hours patterns. Most do not.

Longer hours are more readily expected of managers and senior professionals than of frontline or junior staff.

Your award or enterprise agreement may allow hours to be averaged over a roster cycle of up to 26 weeks under s63, or you may have an individual agreement under s64.
