The 38-Hour Week: Maximum Weekly Hours Under the NES

The 38-hour week lives in article 62 of the Fair Work Act 2009. Its first subsection sets the limit: an employer must not request or require an employee to work more than a set number of hours in a week unless the additional hours are reasonable. For a full-time employee, that number is 38 hours. For an employee who is not full-time, it is the lesser of 38 hours and the employee's ordinary hours of work in a week (art. 62(1)).

Read that carefully. The law does not say you can never work more than 38 hours. It says your employer cannot require more than 38 hours unless the extra hours are reasonable. The 38-hour week is a ceiling on what can be demanded of you without justification — not an absolute cap, and not a statement about how the hours are paid.

This is the point that trips people up. Article 62 governs how many hours you can be required to work. It says nothing about the rate you are paid for going beyond them.

The Act itself gives the game away. Among the factors for deciding whether additional hours are reasonable, art. 62(3)(d) lists "whether the employee is entitled to receive overtime payments, penalty rates or other compensation" for working them. In other words, the Fair Work Act points outward — to your modern award, enterprise agreement or contract — for the overtime rate. There is no statutory overtime multiplier in Australia. The 38-hour week qualifies an hour as "additional"; your award decides what that hour is worth.

So if you are wondering "am I owed overtime pay for my 41st hour this week?", the honest structure of the answer is two-part: yes, hours beyond 38 are in principle additional/overtime hours (art. 62), and the rate for them comes from your award or agreement — not from this article.

The 38-hour standard is not a soft target. The NES "set minimum standards that apply to the employment of employees which cannot be displaced, even if an enterprise agreement includes terms of the kind referred to in subsection 55(5)" (art. 61(1)). And when the Act lists the ten NES matters, maximum weekly hours comes first — art. 61(2)(a).

That ordering is not decorative. It reflects that the limit on weekly hours is foundational: an award or agreement can add to your protection (higher rates, tighter thresholds, better averaging), but it cannot strip below the NES floor. Your 38-hour standard travels with you regardless of what your contract says.

The 38-hour week does not always mean "never more than 38 in any single week." The Act allows hours to be averaged over a period, so that a heavier week can be balanced by a lighter one, provided the average stays within the standard.

There are two averaging routes. Article 63 allows averaging terms in a modern award or enterprise agreement — the instrument sets the period over which hours may be averaged. Article 64 allows an agreed averaging arrangement between employer and employee for those who are award- and agreement-free. If an averaging arrangement applies to you, it changes how the 38-hour threshold is calculated — and therefore when an individual hour counts as overtime. That is why, before qualifying any hour as "extra", you should check whether an averaging term is in play.

Here is the practical upshot for someone auditing their own hours. If you are covered by a modern award, that award sets your ordinary hours — often 38 a week, but sometimes arranged differently — and overtime is triggered when you work beyond them.

If you are not covered by an award or agreement, there is no award threshold to apply. In that case, the 38-hour NES standard is the qualification line: hours beyond 38 in a week are the ones to treat as additional. What you are certainly owed for any unpaid hour — award or no award — is its value at your ordinary hourly rate (a 1:1 floor), checked against the National Minimum Wage, which from 1 July 2026 is $26.44 per hour ([2026] FWCFB 3500). Any overtime premium on top depends on identifying your award. This is why a good audit tool defaults to a 38-hour threshold and flags the result as "to be qualified with the award."
