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.
