European unions push for legally binding workplace heat protections

European trade unions are pressing the European Union to turn workplace heat protection into law, arguing that another punishing summer heatwave has made voluntary guidance inadequate.

The push is being led by Effat, the European Federation of Public Service Unions and the European Federation of Building and Woodworkers. Together, they want the EU to adopt enforceable rules that would require employers to assess heat risk, provide shade and water, and give workers rights to breaks and adjusted hours when temperatures become dangerous.

The campaign is being framed around a forthcoming EU Quality Jobs Act, which the European Commission has said it will bring forward this year. Unions want any new labour package to include a specific workplace heat provision rather than leaving the issue to softer recommendations.

What the unions want

The draft described in the reporting would set legal thermal limits using wet-bulb globe temperature, or WBGT, a measure that accounts for heat, humidity and radiant temperature.

According to the reporting, maximum WBGTs would range from 30C to 32.5C depending on the intensity of the work. Work would be suspended above those thresholds.

The text also calls for mandatory heat-risk assessments at job sites, plus practical protections such as water, shade, cooling and heat breaks.

It would also expose employers that ignore the rules to what the draft describes as effective, proportionate and dissuasive sanctions.

Why the issue is moving now

The unions are using the June-July 2026 heatwave to push a problem that they say has been building for years. Earlier coverage this summer highlighted how extreme temperatures are already affecting productivity and worker safety across Europe, especially in outdoor and physically demanding sectors.

Those sectors include construction, agriculture, food production and public services, where workers often cannot avoid high temperatures and existing protections can be uneven.

Union leaders argue that the current European legal framework does not go far enough to protect workers from heat stress. Effat general secretary Enrico Somaglia said the current framework is not sufficient to protect workers from heat stress.

The broader public-health concern is straightforward: as heatwaves intensify, more workplaces are being forced to confront conditions that can quickly become dangerous for workers who are outside or near hot equipment.

Political stakes in Brussels

The proposal has moved into the political debate because it could shape the content of the Quality Jobs Act and, depending on how far it goes, create a more harmonized baseline for workplace safety across the bloc.

That would be a significant shift for employers and national governments. Binding EU standards could force companies to change schedules, suspend some work during peak heat and invest more in site-level protections.

The idea is gaining traction with sympathetic MEPs and officials. Finnish Green MEP Maria Ohisalo is supporting the union push and serves as rapporteur for a parliamentary report on extreme temperatures at work.

But the plan is not yet law, and it faces resistance from some labour ministers in rightwing EU states, who prefer weaker recommendations over enforceable rules.

What happens next

The immediate question is whether the European Commission takes up any of the union language and folds it into the Quality Jobs Act proposal.

If it does, the next fight would be over how strict the standards are, how they are enforced and whether member states accept binding minimums or dilute them into guidance.

For unions, the goal is to make heat a routine workplace safety issue, not a crisis managed ad hoc every summer after temperatures have already risen.

The debate is likely to stay active as the heatwave continues and as Brussels prepares the next round of labour policy.
