Chicago Teachers Union

The Chicago Teachers Union (CTU) is a labor union that represents teachers, paraprofessionals, and clinicians in the Chicago public school system. The union has consistently fought for improved pay, benefits, and job security for its members, and it has resisted efforts to vary teacher pay based on performance evaluations. It has also pushed for improvements in the Chicago schools, and since its inception argued that its activities benefited students as well as teachers.

The CTU united several teachers' organizations in Chicago in the wake of a teachers' revolt against banks during the Great Depression. It was chartered in 1937 as Local 1 of the American Federation of Teachers (AFT), in which it played a founding role. It was the largest and most active AFT Local until the 1960s. The CTU won collective bargaining rights in 1966 and conducted several strikes during the 1970s and 1980s. In September 2012, the union began its first strike in 25 years.

The CTU is also affiliated with the Illinois Federation of Teachers, the Chicago Federation of Labor, and the AFL–CIO. It has more than 25,000 members. Current officers come from the Caucus of Rank-and-File Educators, elected in 2010 to replace the longstanding United Progressive Caucus. From that point until her 2018 retirement, Karen Lewis was president. Through a successors election the new officer slate became: President Jesse Sharkey, Vice President Stacy Davis Gates, Recording Secretary Michael Brunson and Financial Secretary Maria Moreno. Following the departure of Sharkey, Stacy Davis Gates assumed the role of President on July 1, 2022.
