I think it would be better for everyone to get four days a month to choose as days off. Then it would be better distributed. I would prefer this to a four work week. After a few days in a row the freedom really sinks in, so I'd love to be able to take a week off every month, guilt free.
The French Republican Calendar had five/six complementary days [0] at the end of the year that were part of no particular month. They were, however, spent contiguously between summer and fall, rather than between each season.
