The 4-day week could potentially revolutionize the world of work. But not all business representatives are convinced of this model.

Ex-Trigema boss Wolfgang Grupp describes the model as doomed to failure. A pilot project currently underway is intended to clarify this. The study will implement the 100:80:100 model already used by the non-profit organization 4 Day Week Global. In terms of concrete terms, this means: 100 percent salary for the commitment of 100 percent of the work performance.
