Liberalisation of industrial relations entails the weakening of unions and a respective rise of alternative, ‘new labour actors’, altering traditional class representation by introducing new strategies. Research on this phenomenon has focused on decentralised contexts, where new actors are seen to pursue both independent strategies as well as cooperation with unions to contest rising employers’ discretion. Drawing on multiple qualitative methodologies, this article analyses the roles and contributions of new actors in the context of corporatist industrial relations, to find rising conflicts between them and unions. Combining social movement theories of strategic change with industrial relations theories of power and theories of institutional complementarity, reveals conflictual forms of complementarity between new actors and corporatist unions. Through interacting with new labour actors, corporatist union strategies are seen to change in a ‘spin-off’ form, reforming unions’ traditional power and dominance to (partially) counter previous liberalisation of industrial relations.

劳资关系的自由化需要工会的削弱和替代性“新劳动者”的兴起，通过引入新的战略来改变传统的阶级代表。对这种现象的研究集中在分散的环境下，在这种情况下，新的参与者被认为既追求独立战略，也追求与工会的合作，以对抗日益增长的雇主的自由裁量权。本文利用多种定性方法，分析了在社团主义劳资关系背景下新参与者的角色和贡献，以发现他们与工会之间日益加剧的冲突。将战略变革的社会运动理论与劳资关系的权力理论和制度互补理论相结合，揭示了新参与者与法团之间的互补形式的冲突形式。
