From the union's formation in 1937 until the 1960s, the Chicago Teachers Union (CTU) was the largest and most influential teachers' union in the country. John F. Lyons examines the role of public schoolteachers and the CTU in shaping the policies and practices of public education in Chicago. Examining teachers' unions and public education from the bottom up, Lyons shows how the CTU and its members sought rigorous reforms. A combination of political action, public relations campaigns, and community alliances helped the CTU to achieve better salaries and benefits, increased school budgets, reformed curricula, and greater equality for women within the public education system. But its agenda was also constrained by internal divisions over race and gender and by ongoing external disputes with the school administration, politicians, and business and civic organizations. Detailed and informed by rich interviews, Teachers and Reform: Chicago Public Education, 1929-1970 tells the story of how committed union members effected changes to public education and to local politics that still benefit Chicago teachers, students, and the city today.
