The analysis of collective bargaining coordination has attracted the attention of scholars and policy-makers since the early 1990s, but has witnessed a renaissance more recently. Originally, ‘coordination’ was presented as a dimension of collective bargaining that was considered an alternative to ‘centralization’, as it focused on processes rather than structures. However, the reality was that all coordination indexes and scores have tended to reflect structural characteristics of collective bargaining, and have provided very little insights on the processes and relational aspects underpinning coordination.

Despite growing research on the comparative analysis of collective bargaining coordination and its impact, we still lack deeper knowledge about: the mechanisms sustaining coordination; how information flows between actors in the collective bargaining structure; the exact role played by different organisations / actors; the way in which actors and the different levels of the collective bargaining structure are articulated, including the national and trans-national.
