Education for Mobilization: The Effects of Knowledge about Labor History on Union Support

The US working class is less organized along class lines than in other advanced democracies. We propose a new explanation: the absence of education on historical class struggle and labor organizing weakens support for the contemporary labor movement. To test this, we conduct two survey experiments exposing respondents to educational videos about the history of an American union and present-day union drives. Our surveys focus on non-college-educated whites in the US South, where union membership is low and racial conflict has historically constrained class-based solidarity. We find that exposure to labor history increases enthusiasm for unions and cross-racial class coalitions. These effects appear to be driven by greater political efficacy, better understanding of unions’ material benefits, linked fate with the working class, and increased allyship with marginalized groups. Our findings suggest that labor history education can shift political attitudes and foster greater class-based mobilization, even in contexts historically resistant to such organizing.
