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.
Public sector employees are highly engaged in civic and political life, from voting to volunteering. Scholars have theorized that this political activity stems from “public service motivation,” or the selection of publicly oriented individuals into public work. We build on this work by analyzing the role of public sector unions in shaping participation. Unions are central mobilizing organizations in political life, and one in three public sector workers are unionized. Special supplements of the Current Population Survey provide data on various forms of participation, sector, union membership, and union coverage. Logistic regressions find that unionized public sector workers have much higher odds of engaging in a range of activities compared to non‐union public workers, including protest, electoral politics, and political communication. Union membership impacts service work to a lesser extent, suggesting that unions are more central to political lives. These findings have implications for the consequences of union decline, including the class, race, and gender composition of who participates in democratic life.
