Supermajority of people would probably enjoy 4-day work week, but there needs to be a giant push from the labour side. All the needs of "big companies" and such theoretically could be ignored, if such supermajority stuck together, and pushed through legislations. But I fear, this push will resonate with the word "unionization", killing all the efforts, since there is a hate towards such movements.
