I can't imagine what a nightmare it would be for parents who needed childcare. Ugh. Or what a bunch of tweens/teens will be getting up to all day while Mom & Dad are at work.
Also, I worry about the kids to get their main nutrition at schools. Do they just go hungry on Friday?
I hear what you are saying but it is not eh schools responsibility to be
A) childcare
B) Nutrition
C) babysitters for teens/tweens
Thats part of what I think has to change...the thoughts that many people seem to feel school is responsible for "raising" so many of these kids...its up to parents to make those decisions, though they are often tough ones to make, "parenting" is no piece of cake and a
full time responsibility, IMHO.
As far as a 4 day week, I think back to when they gave us Micro classes (HS) , every 20 minutes we went to the next class, a total FLOP....my ds gets No lunch now (by choice) he chooses to take extra classes, both college level and languages, but I still think he'd be thrilled to be off for 3 day weekends....generally speaking he works 95% of each weekend anyway...but maybe thats just HS, cause I do not recall that in MS.
For the little kids.....our district was 1/2 day kindergarten for a long time and only in last few years went full day....many many parents were thrilled ( I was not one of those) it was not because kids were "learning more" but because it made for better/easier childcare issues

I get that! Me, I was also one of those moms that did not send my baby off to nursery school, pre K and on and one for
years before he started...though I do not judge those either its a choice...(and I have One Very smart cookie, if ya ask me

) So,
....I am not really sure what is in the BEST interest of the kids....long days are tough...for Kids, teachers, and Admin alike! Just my 2 cents
