Dutch high school students rampage against extra hours

First of all, since when do high school kids have a union? Since when do 16 year-olds go on strike? The national government is making them stay in school for a certain number of "useless hours" per year -- corralled into boring study halls when there is no teacher available. So the kids went on strike. They texted and IM'd and organized and threw eggs at Parliament, tipped a car and set it on fire, clashed with riot police in several cities. Police dragged a kid into a van, and the other kids rescued him. Some coverage here and here. Video of a police water cannon being used on the children is here. In my day, it never would have occurred to us to go on strike and take to the streets in protest of study hall hours. I, for one, was too busy sleeping in study hall.
