The standard 5-day, 40-hour work week is a form of modern-day corporate slavery. It was invented over a century ago for factory workers and makes absolutely no sense for the modern era. You spend the best days of your life making someone else rich while getting two days to clean and rest.
A 4-day work week has been proven to increase productivity, happiness, and overall mental health. We are sacrificing our families and our health just to uphold an arbitrary, outdated industrial schedule.
