Unity and diversity: Challenges to an expanding Canadian Autoworkers' Union

In response to declining memberships, trade unions are expanding their membership base by organizing the unorganized and by merging with existing unions. Through an examination of the Canadian Autoworkers' Union, this paper argues that to reap the benefits of greater size, unions must be able to represent the diverse and competing claims of their expanding membership while at the same time being capable of building internal unity. These tasks become more difficult as unions seek membership among new groups of workers. The paper argues that unions' collective identity and organizational structure are critical factors in determining how new union members are brought into a new union. The paper concludes that the CAW has embarked on a rapid and uneven course of organizational and cultural change, the result of which could be future problems for the CAW in mobilizing collective support for its goals.
