Although social investment has become an increasingly important topic in the welfare policy discourse, reform efforts are stalling in many contexts. We examine whether labour unions and their members may be one factor contributing to the varying implementation across countries. In particular, we focus on the difference in the policy attitudes of union members and non-members. Using a new comparative survey, we investigate how union member attitudes toward social investment and classic compensatory policy differ from those of non-members, and how these differences vary across countries. We find that union members appear to be lukewarm supporters: even though union members are generally supportive of social investment policies, they tend to support compensatory policies even more. We also find cross-national variation in these associations, for which we provide some tentative explanations.

尽管社会投资已成为福利政策中越来越重要的话题，但改革努力在许多情况下都停滞不前。我们研究了工会及其成员是否可能是导致不同国家实施情况不同的因素之一。我们特别关注工会会员和非会员在政策态度上的差异。使用一项新的比较调查，我们研究了工会会员对社会投资和经典补偿政策的态度与非会员之间的差异，以及这些差异在不同国家之间的差异。我们发现工会成员似乎是不冷不热的支持者：尽管工会成员一般都支持社会投资政策，但他们倾向于更加支持补偿性政策。我们还在这些协会中发现跨国差异，
