I'm curious how much of the 4-day workweek movement is driven by religious obligation. Jews rest on the Sabbath which typically falls on Saturdays, plus high holy days. Christians rest on the Lord's Day, which falls on Sundays, plus holy days of obligation for Orthodox, Catholic, etc. Up until now in the Western business world we've standardized on a five-day week which allows Jews and Christians to have their rests, and soccer moms to have their bloody soccer matches. But with an increasing number of Muslims in the mix, there is a demand from Muslim faithful to rest and pray on Fridays. Create a four-day work week and now you've got 3 days of rest, 1 for each type of Abrahamic faithful person to go pray. Muslims already have won major concessions in terms of prayer times and spaces in office buildings, college campuses, etc.
