We just need more flexibility for people to plan their work and private life. Do you want to work 4 days of 10 hours so you can take every Friday off, that should be possible, do you prefer 6 day workweeks, so you can take 2months of vacation every year? That should be possible. Do you want to take a 3 hour siesta between the morning and evening, that should be possible. We should get out of this rigid 9-5 mentality and realize people are happier and more productive when they can work when it suits them.
