The New York CityTeachers Union or "TU" (1916–1964) was the first New York labor union for teachers, formed as "AFT Local 5" of the American Federation of Teachers, which found itself hounded throughout its history due largely to co-membership of many of its members in the Communist Party USA (CPUSA).[1][2][3][4][5]
