This chapter shows how the bottom-up organization of CTERA was crucial for movementism. The mark of the activist base on protests is reflected in the fact that protests were organized primarily at the provincial and municipal levels, were widespread across provinces, and recurred over time. The chapter then examines the union’s role in electoral politics. While some union leaders became politicians, the union was not beholden to any political party and it lacked a coherent partisan identity. The last section analyzes the policy dynamics that ensued from movementism and the extent to which the creation of a new national institution of collective bargaining for teachers transformed the union’s political repertoire. It is shown that movementism remained largely in place.
