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.

Its probably way too late to implement something like this but the idea is still a good one.

Thinking of it, wasn't there a "metric" calendar or something that sort of did this?
