When the Caucus of Rank-and-File Educators (CORE) endorsed two of our members as Teacher Trustees for the Chicago Teachers Pension Fund, we formulated a strategy that strayed far from the expected route. On October 30 our strategy yielded a big win for the rank-and-file movement within the 32,000-member Chicago Teachers Union (CTU). This was the first time that incumbents who were members of the ruling caucus in the CTU lost their seats to a reform group.
