Teachers and students in Wisconsin are protesting Governor Scott Walker’s budget bill. But it’s not a mark of democracy: instead, teachers have been taking kids out of school to march on the Capitol in Madison. It’s being called a “sickout” — and it’s illegal.

“Teachers are joining protests planned today at the State Capitol,” one witness to the protest said. “Yesterday, more than half of the student body of Madison East High School walked out with the support and assistance of their teachers.”
