Labor Union Political Strategy in an Era of Decline and Revitalization.

U.S. labor unions faced sharp membership losses over the last few decades, and some responded by ushering in a new, revitalized model of organizing. Yet we know little about how these forces may be shaping the political activities of the labor movement. Has crisis prompted unions to take aim at public policies inhibiting union vitality, or have unions turned outward to embrace broader social causes? This paper uses an original dataset of union appearances in congressional hearings to analyze unions' legislative advocacy activities. Findings suggest substantial differences between those unions that are likely to appear in hearings on core labor-related topics and those that appear in hearings on broad social issues: AFL- CIO unions are more likely to participate in hearings on core labor issues, while unions commonly cited as 'revitalized' and public sector unions are more likely to appear in hearings on broad social issues.
