I technically most often work 5x8 per week. But with the amount of vacation and paid days off I get, it is more like 5x6 over the whole year.
And yeah, it is really nice especially for mental health. When I worked 40 hours or more at my old job, I just worked ate and slept basically aside from one day on the weekend to actually do anything. I didn't even make much money, and probably would have developed more physical problems if I kept working there, which would end up costing far more than the amount that I got paid.
So I would definitely recommend modern day companies to get the with the times. 30-32 hour workweeks are great!
