AbstractThis article looks at the hospital European Sectoral Social Dialogue Committee (SSDC) through a Community of Practice (CoP) theoretical lens. Based on a 2‐year project, qualitative in‐depth interviews at the European level and in five Member states, and participant observation of the hospital SSDC, we propose a shift from traditional institutional and resource‐based accounts and provide a learning and knowledge‐focused understanding of this specific area of European industrial relations. Interpreting the SSDCs as a CoP sheds new light on the role of power relations, participation and informal activities among members and on how they work together; this, we find, can alert those interested in more effective functioning of the European Sectoral Social Dialogue on how to strengthen this supra‐national level of industrial relations.
