The Chicago Teachers Union is preparing for a "day of action" on Friday with rallies and protests to take place from early morning through the evening. What are the alternatives for parents who need to drop their kids at school, what is the strike about, and is it even legal? 

Parents of Chicago Public Schools students still searching for alternatives to attending school this Friday will have their pick of 262 contingency sites announced today by the district. Meanwhile, the Chicago Teachers Union has released a tentative schedule of events, which includes picketing schools and rallying downtown during rush hour.
