University campuses experienced a surge in protest activity around labor issues during the late 1990s, highlighted by several highprofile graduate employee unionization campaigns. Some scholars and activists attribute these developments to notable changes in the academy, while others note that this wave of activity coincided with revitalization efforts by the broader U.S. labor movement that included reaching out to new constituencies and college students in particular. The authors advance this discussion by analyzing the factors leading to graduate employee union organizing campaigns between 1996 and 2001. They draw from social movement and labor research to suggest how shifts in the nature of academic labor markets, local resources and opportunities for activism, and increased links between organized labor and college campuses influence the timing and location of organizing campaigns. Results from an event history analysis of campaign activity largely support these claims and highlight the importance of local resources and opportunities for campus organizing.
