This article examines the relationship between income inequality and collective labor rights, conceptualized as workers' legal and practical ability to engage in collective activity. Although worker organization is central to explaining income inequality in industrialized democracies, worldwide comparative studies have neglected the role of class-based actors. I argue that the repression of labor rights reduces the capacity of worker organizations to effectively challenge income inequality through market and political processes in capitalist societies. Labor rights, however, are unlikely to have uniform effects across regions. This study uses unbalanced panel data for 100 developed and less developed countries from 1985 through 2002. Randomand fixed-effects models find that strong labor rights are tightly linked to lower inequality across a large range of countries, including in the Global South. Interactions between regions and labor rights suggest that the broader context in which class-based actors are embedded shapes worker organizations' ability to reduce inequality. During the period of this study, labor rights were particularly important for mitigating inequality in the West but less so in Eastern Europe.
This research demonstrates that the union wage premium is higher for Black and women workers in the US public sector, what we refer to as “an intersectional union premium.” Union mechanisms reinforce and expand the more equitable practices of the public sector, resulting in this additional boost. Using Current Population Survey data, 1983–2018, this research models intersectional effects on earnings by examining interactions between union membership and race–gender. Relative to White men, union membership boosts average earnings an additional 3% for Black men and Black women, and 2% for White women on top of the direct union premium. Corollary analyses reaffirm these effects in multiple state contexts, including by union density and union coverage. Intersectional union premiums are weaker in states that prohibit collective bargaining. These premiums are present across most types of public work, with the exception of police and fire employees. To conclude, the authors discuss how changing labor policies may impact race and gender equity in the public sector.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
