I have worked with excellent people at ING in Amsterdam as an external IT consultant. While helping them to engineer their new platform strategy, I experienced that they are one of the best companies I have worked with in terms of culture, tech stack and hourly rate among all European clients we had during the past 11 years. Many employees opt-in for a 4-days week since it became really popular during the last few years. I think a 4-days week is more attractive for employees and tech companies in many aspects than a 5-days week. The 5-days week was established in times where work was mostly manual or repetitive. It was a historical trade-off between companies and the working society that evolved over the last centuries. But nowadays many jobs require creative and mental work which can not be placed into a linear time-scale in comparison to the idea of assembly line workers where companies can add more persons and the productivity output is mostly increasing linearly. People pursuing occupations with a high amount of mental work keep solving complex problems during and outside their working time. Probably you also remember a moment when you thought about a problem you are trying to solve and you found the solution at any random place and time. The 4-days week enables people more flexibility to organize their life around the the complex challenges that are being solved by companies they work at. P.S. +1 adding ING to the list
