Redefining influence: how a feminist advocacy group reformed paternity leave in Spain through insider women’s alliances

Abstract How do citizen interest groups influence policy in domains dominated by political and economic elites? Recent research suggests their success hinges on outsider strategies to pressure policymakers, such as mobilizing public opinion. In contrast, a feminist platform named Platform for Equal and Non-transferable Birth and Adoption Leave (PPiiNA) built insider alliances with female politicians across party lines to make paternity and maternity leave equal and non-transferable in Spain in 2019. This article explores this case in depth by tracing almost 20 years of policy evolution through parliamentary documents and interviews. Against employer opposition and the absence of trade unions, the case corroborates the relevance of women in politics by illustrating how descriptive representation can open insider channels of influence to feminist advocacy groups. Nonetheless, the approval of the reform ultimately depended on left-wing governing power, while policy formulation was dominated by political elites and employer groups, limiting the capacity of cross-partisan feminist alliances to shape final policy output.
