This chapter analyzes the organizational prerequisites for the strategy of instrumentalism, by charting changes in the organizational structure of the National Educational Workers Union (SNTE) of Mexico in the 1980s and 1990s. It examines the threats to the corporatist model posed by the dissident movement and the regime response to help the union leadership regain control. President Carlos Salinas sheltered the union from the potentially disruptive effects of education decentralization policies and strengthened SNTE with policies to improve teacher pay. These concessions shaped the union’s internal organization, providing the resources Elba Esther Gordillo needed to build a dominant faction. The consolidation of power in the national union leadership was crucial for the strategy of instrumentalism.
