What Do Unions Do for Mothers? Paid Maternity Leave Use and the Multifaceted Roles of Labor Unions

The authors present a four-fold conceptual framework of union roles—with a focus on availability, awareness, affordability, and assurance—for enhancing workers’ paid maternity leave use. Using a panel data set of working women up to age 31 constructed from the National Longitudinal Survey of Youth 1997, the authors find union-represented workers to be at least 17% more likely to use paid maternity leave than are comparable non-union workers. Additional results suggest that availability, awareness, and affordability contribute to this differential leave-taking. The authors also document a post-leave wage growth penalty for paid leave-takers, but do not find a significant union–non-union difference.
