Here is something most businesses schedule around without realising it: human biology. The time at which a person does their most focused, creative, or complex work is not a preference — it is a genetic predisposition. Researchers call it your chronotype, and it determines whether your brain is firing on all cylinders at 7am or 7pm.

Morning types (often called “larks”) peak early. Evening types (“owls”) often do not reach cognitive peak until mid-morning or later. Most people fall somewhere in between — but the distribution is far wider than the standard 9-to-5 working day assumes.

 

The business case for flexibility 

A 2023 study published in the Journal of Sleep Research found that workers whose schedules aligned with their chronotype reported significantly higher levels of focus, creativity, and job satisfaction — and significantly lower levels of burnout. The same study found that forcing night owls into early starts created a chronic, low-level performance drag that was almost invisible in the moment but compounding over time.

For Australian businesses navigating skills shortages and retention challenges, this is not a soft wellness consideration. It is an untapped performance lever. If your best analyst does her clearest thinking between 10am and 1pm, scheduling her most important work — or her most critical meetings — at 8:30am is costing you output.

 

What you can actually do 

You do not need to tear up your entire operating model. Three practical adjustments:

1. Audit where flexibility already exists and whether it is being used.

Many teams operate with informal flexibility that is never formalised — and therefore never optimised. A structured conversation with your team about when they do their best work costs nothing.

2. Protect “deep work” windows.

Even one two-hour block per day where people can work without meetings or interruptions — at a time they choose — can materially improve output quality.

3. Reconsider your default meeting times.

If your all-hands or team meetings cluster between 8 and 10am, you are catching a meaningful proportion of your team before their brains are at capacity.

This is not about enabling people to sleep in. It is about understanding that human performance is biological, not bureaucratic — and that the businesses willing to work with that reality will get more from their people than those who insist on uniformity.
