Through the eyes of public school teachers fighting for the benefit of all their students, SCHOOLIDARITY tells the interwoven story of the two most significant workers' rights struggles of our time: the weeks-long 2011 mass occupation of the Wisconsin capitol, and the Chicago teachers strike of 2012. SCHOOLIDARITY provides a history of the issues surrounding the privatization of urban public schools in the US. By documenting the ascent of the activist teacher caucus CORE, Chicago's public schools crisis is analyzed through the lens of the assault on public sector unions, where defeats are just as important to study as victories in order to insure education justice for all.
