These people spend more time on strike than they do teaching.
Via Chicago Tribune:
After spending the morning on the picket lines, some Chicago Public Schools teachers on Friday headed to college campuses to join allied forces in protest of budget cuts and the lack of state funding for education as part of the “Day of Action,” which will culminate in an afternoon rush-hour rally at the Thompson Center in the Loop.
Classes were canceled Friday for the more than 300,000 public school students because of the one-day walkout. Instead, teachers and their supporters marched in front of their schools, offering chants, playing instruments and pumping signs — one offering the ultimate Chicago slam: claiming Gov. Bruce Rauner and Mayor Rahm Emanuel use ketchup on their hot dogs. All of it aimed at drawing attention to the failed contract negotiations between the union and CPS as well as the budget stalemate in Springfield that could further cripple the already cash-strapped school system.
