The IT company IIH Nordic is based in Denmark, where the working week is usually 37 hours. Since 2017 the company has operated with a four-day working week – eight hours a day, 30 hours a week. All 50 employees still receive the same salary as they did before, but now with every Friday off. Although the company’s work week is reduced by a full day, it still produces as much as it did with a five-day week and has increased its bottom line significantly.

This company is the first of its size in the world to have made such radical changes in working hours over such a long period of time. IIH Nordic has won several awards for its working environment. It serves as a shining example to the rest of the world that you can have an ambitious working life and enjoy great commercial success without necessarily sacrificing your freedom, health or family time.

You will find the secret of their success in this book. It contains concrete facts and unique insights from the four-day work week, interviews with employees and experts, plus a number of simple tips and tools that you can apply in your working life, present to your boss or implement in your own business.
