If a school has designed its programmes so that operating for all of the days in a school week is infeasible with their budget (which doesn't make sense to me, since I don't think they could reduce teacher salaries by removing a day, and I can't imagine any other cost making it worthwhile), then they have done something wrong. Wouldn't it be great if, at the cost of children playing latchkey for a day during a school year or two (or however long it takes them to fix this), they finally get their act together again.
