At one point in my career I had a 4-day week and let me tell you that it was glorious. Instead of barely having time on the weekend to recover from the eat-work-sleep daily grind, I actually had some time to feel human again and even spend some money on a hobby. A hobby!
At one point I had every other Friday off and even having the three day weekend only every other week was really refreshing and such a nice break. I miss it, I’ve been hoping it becomes more common.
