iak – seriously? Is that an old prejudice that lingers on? I have no doubt many of the yeshivos had no such thought (even if some did).
In my city I heard people complain that if the school closed for a day, they want a make up day or a refund. And do you think the teachers want a make up day? Many would rather just open (I work in a public school where many made the same comment)
Trust me, many of the parents don’t want the kids home and resent days off. Many work and don’t have child care options. Many don’t have the patience, and many can’t stand watching their kids spend the day playing video games. Whatever the reason, don’t be so sure you can speak for them all(or any?)
