It depends on the schools, really...but based in my area it would be public school and less work without a doubt. Not just to be home in the afternoon, but to be able to have the flexibility to attend things...like assemblies when your child is getting an award, Easter Hat parades, reading in class etc etc. School has so much that involves the parents. Plus, having that one day means you get to meet the other parents...which is nice because you don't have to wonder if it's okay for your child to have a playdate. And as a bonus...I have such great friends that are fellow school mums.
