Businesses Want Maximum Productivity, But Will Workers Get a Maximum Temperature?

In the Northern Hemisphere, workers are again facing dangerous summer heat. In a few months, it will be the Southern Hemisphere’s turn. Climate extremes are producing droughts, wildfires, and crop failures. It’s not the end of the world, but it’s becoming easier to see how the world ends, and how work and business will be affected. As with most catastrophes, occupational health and safety (OHS) sits quietly in the background. It needs to step forward because it has tools that can help.

Maximum Workplace Temperatures: A Political Fix Searching for an OHS Problem

The United Kingdom and Europe are again struggling through dangerous summer heat. In Australia, it’s tempting to feel a little smug. We’ve spent decades adapting our houses, cities and work practices to heat: wide‑brimmed hats in schools, backyard pools, ventilation, shade, job rotation, and a long list of practical controls that employers and regulators understand well. None of this makes heat safe, but it does make working in excessive heat manageable.

Into this UK heatwave steps Greens MP Hannah Spencer, proposing a Private Member’s Bill to establish a maximum workplace temperature.

Working Hot and Thinking Smart

In 2021, Safe Work Australia released a model Code of Practice (CoP) for Working in Extreme Heat. The latest iteration of that code was released by the Australian Capital Territory on November 7, 2025. It is greatly expanded and much clearer on the prevention and management of exposures. When companies are claiming “best practice” safety, this CoP is particularly interesting.

Heat, Harm and the Cost of Denial

As Victoria shivers in the middle of its Winter and a cop-killer runs loose in the mountains in the middle of the state, it may seem odd to think about the occupational health and safety (OHS) context of working in excessive heat. However, give us a couple of months, and it will be a hot topic again in the Southern Hemisphere. (First and last weather pun, I promise)

A recent article in The New York Times (paywalled) examined excessive heat in Spain, providing useful details on the changes being implemented—some old, some new.

Lessons on management of heat from the Australian Tennis Open

One of the best articles about managing heat exposure at work is by Madi Chwasta of the Australian Broadcasting Corporation, who wrote about the Australian Open tennis tournament.

Tennis is usually played outdoors in summer, at least in Australia. The Australian Tennis Open, held in Melbourne, was heavily promoted and had a high public attendance rate. Some tennis matches are conducted in facilities with retractable roofs, but many others are held on outdoor courts with limited shade and no air conditioning.

Working in Heat, and Gwarda

New research into working in excessive heat concisely summarises the socioeconomic impacts but misses the obvious strategies to prevent or diminish these impacts. It also includes impacts on productivity, but heat and climate change are not in the current Australian business group discussions about productivity. Those groups could benefit from understanding Gwarda.
