3 day work weeks are best.
Most well paid developers would gladly take a 20% reduction in income for 50% more weekend right? So 4 days it is!
Well why stop there? I’ll take another 25% reduction for 33% more weekend. So 3 days it is!
But only the rich or a fool would then take an additional 33% reduction for a measly 25% bump to your weekend.
