This chapter shows how a hierarchical organization and a dominant faction were crucial prerequisites for the strategy of instrumentalism. The union’s hierarchical structure enabled it to mobilize teachers in elections and a dominant faction enabled negotiations with political parties from across the ideological spectrum. The last section analyzes the political backlash against instrumentalism in 2013, which resulted in leadership turnover and policy changes that weakened the union overall. Despite this backlash, however, the union’s internal organization remained largely intact and union leaders continue to be ideologically flexible, in line with the main argument in this book.
