When Do Mass Labor Strikes Reshape the Public? New Findings and a Research Agenda for Political Science

Abstract

I consider the role of exposure to large-scale strikes in shaping preferences about workplace action and labor unions, replicating and extending past work identifying the effect of large-scale teachers’ strikes. I study a large 2019 grocery store strike. Using an original survey fielded in affected states and an instrumental variables design, I find strike exposure increased support for the strikes, including actions taken supporting the striking workers. I do not find consistent evidence that strikes increased interest in online actions to support other workers or in workers taking most forms of labor actions at their own jobs. Firsthand contact with strikes had no effect on individuals’ broader perceptions of the labor movement or support for a union at their job. These results suggest important distinctions between strikes. Suggestive evidence indicates that the grocery strikes may have failed to inspire a greater sense of linked fate between affected members of the public and striking workers, as had occurred with teachers’ strikes. I conclude by laying out a research agenda for understanding the impact of mass strikes.
