I heard of a case where a worker took one day off from work every week. His boss finally got fed up with it and asked him why he consistantly worked four days a week.
His answer, "Because I can't make enough in three."
On the other hadn, before I retired, I tried several times (unsuccessfully) to institute a program where once you turn 55 you get three day weekends every week but at the same pay. At 60 you'd go to four day weekends. At 65 - five day weekends, etc. until eventually you'd have seven day weekends every week and still get the same pay.
I couldn' get enough interest and now I already have seven day weekends every week.
