The only thing about this whole post that bugs me is the tone. The whole "the school district can kiss my butt" concept. This is a place where you put your child for thousands of hours a year -- these people teach and train and nurture and prepare your child for the world. Now, maybe they don't do it exactly the way you want them to, but they do it. On less money than they need and with fewer people than they should have. But they should kiss your butt because they have vacation guidelines?
We put all of these requirements on our school systems -- keep my kids safe, teach my kids, give them discipline, let them be creative, prepare them for college, teach them to work as a team, and on and on. And if they don't come through, boy are we quick to criticize. But should the school say something silly like, "It's so much easier to teach your children if they're actually here, so we'd like you to limit vacations during the school year" and all of a sudden they're the bad guys.
I get the concept of "they're my kids, so it's my decision." But I think it's unrealistic to expect the school system to not weigh in. The school system is simply telling people what the rules are. They're not saying "You absolutely cannot go", they're saying "If you go, these are the ramifications." For some systems, it means zeroes on work and an unexcused absence. For others, it means doing make-up work or keeping a journal. But no school should be scorned for simply having a policy.
