The showdown in Chicago — the nation’s third-largest school district — pits teachers against Mayor Rahm Emanuel, President Obama’s former chief of staff. Emanuel remains a close ally to Obama, while many of the policies at issue in Chicago are being pushed on a national scale by Secretary of Education Arne Duncan, former Chicago Public Schools chief. We’re joined by Pauline Lipman, professor of education and policy studies at the University of Illinois-Chicago, director of the Collaborative for Equity and Justice in Education and member of Teachers for Social Justice.  It is the first teacher strike in Chicago in a quarter of a century.
