You come back home at Friday at 4 Pm. Then you have a regular free evening. Then you have Saturday – one day. And on Sunday you have to prepare various things for work and pree cook and half the day is gone. Also you know tomorrow the 5 days start anew – this takes away half the joy of your free day.
So the weekend is actually more like 1.5 days instead of full two days. Fridays should be free – or at maximum work until 1 PM. This would be easily reachable if we dexrease the 40 hours week to just 37 or 37,5 hours.
