CHICAGO -- The carefree life on the playground may soon turn to another battle between CPS and the teachers union.
The last strike in 2012 lasted nearly two weeks as teachers protested in the streets and parents scrambled for places for their kids to go.
For a few days now, CPS has sent letters home to parents, telling them about contingency plans, setting up a website to search for the 250 sites set up as safe havens.
Those include 100 churches opening their doors to CPS students.
The sites aren't nearly enough to accommodate 300,000 CPS students, leaving some parents to search for alternatives, for a walkout by teachers union members still in the throes of contract negotiation.
The Chicago Teachers Union has said that teachers who go into work Friday for this scheduled walkout may face disciplinary action.
