Working in the heat, how?!

01-07-2025

Warm weather is nice, but if you have to work all day, it's less enjoyable. Working in the sun or extreme heat can pose risks to your health. What does the CLA and law say about this?

Of course, it's not pleasant to work in extreme heat, but it is not immediately dangerous. Therefore, you cannot simply refuse to work. The CLA does not specify anything about working in warm weather. The law states that you may interrupt your work if the heat poses a serious and immediate danger to your safety and health. The law does not precisely define what is meant by dangerous heat. Not only heat, but also humidity and work clothing can create dangerous situations.

What measures can you take?

Both you and your employer must take measures to ensure that work can be carried out safely. If your employer does not take measures and there is an immediate threat to your safety and health, you may stop working. If working in extreme temperatures cannot be avoided, the employer can:

  • assess whether working in the heat is necessary
  • reduce the duration of work in the heat
  • alternate work with tasks in a cooler place
  • provide cool drinks
  • make personal protective equipment available
  • adjust clothing regulations

Employers may enforce clothing regulations as long as these regulations are reasonable. An arrangement regarding clothing regulations is established between the employer and employee. The law does not regulate this.

Need help?

If your employer does not do enough to keep work in the heat safe and bearable (see tips below as well), you can seek assistance from the Dutch Labour Inspectorate or the occupational health service. 

Tips for temporary measures

  • Do not work for too long consecutively
  • Take breaks in cool areas
  • Ensure extra ventilation
  • Drink plenty of water or sports drinks
  • Turn off heat-producing devices where possible
  • Wear appropriate clothing
