It may save the school some money but it would hurt the pockets of many, everyone who works at schools who would have to take pay cuts and the cost of day care for working parents and day cares would have to take in more children or more added. I don't like the idea of kids being left unattended for a day as I am sure there will be more than there should be as parents won't.can't pay. Our school system now provides food during the summer for the inner city kids who need a meal --they would still have to do that for a day that school wouldn't be in session.
Plus I can't imagine how it would work with athletics as most of our varsity games are played on Fridays evenings so that parents can attend games. More weekday games=less parents coming=more parental complaints. Not to mention many of our academic challenges, theater, music etc., who have many events on Fridays. The students would still be pouring into schools that day to prepare and the schools would have to provide supervision.
They are already complaining we aren't in school enough creating low test scores academically.
Me personally, I'd love a three day weekend, but I just think there are too many obstacles, especially at inner city schools to overcome
