Ideological connections between the state, political systems and industrial relations have long been important. But the influence of the structural nature of a country's political system on trade union membership, coverage and influence has been largely overlooked. We uniquely theorize three channels through which a political system can shape unionization in the workplace independent of ideology: incentives for inclusionary governance, legislative body composition and policy enactment. Empirically, we use multiple European datasets to test the relationship between political and employee representation using multivariate analyses across more than 25 countries. We find that increased political representativeness, measured by lower disproportionality and the presence of multiparty coalitions, is a statistically significant predictor of a greater likelihood of individual trade union membership, coverage and influence, while competitive fragmentation, measured by greater numbers of political parties, is associated with weakened collective voice.

政治制度对工会成员、覆盖面和影响的重要性：理论和比较证据

长期以来，国家、政治制度和劳资关系之间的意识形态联系很重要。但是，一个国家政治制度的结构性质对工会成员资格、覆盖面和影响力的影响在很大程度上被忽视了。我们独特地理论化了三个渠道，通过这些渠道，政治体系可以在独立于意识形态的工作场所塑造工会：激励包容性治理、立法机构组成和政策制定。从经验上讲，我们使用多个欧洲数据集，通过跨 25 个以上国家的多变量分析来测试政治和员工代表之间的关系。我们发现，以较低的不成比例和多党联盟的存在来衡量的政治代表性增加，
