Previous Eurofound research developed three complementary tools to examine the dynamics of industrial relations and compare how national industrial relations systems are faring in terms of quality and change over time. These tools are a dashboard of indicators; an index to measure country performance in industrial relations as a whole, four key dimensions and subdimensions; and a typology of industrial relations systems based on performance in industrial democracy and relevant characteristics of industrial relations systems. This report builds on this previous research and has three main objectives: to revisit and update the index of each of the four key dimensions for 2018â2021 based on new data and indicators; to analyse convergence trends in the key dimension industrial democracy from 2008 to 2021 across national industrial relations systems; and to update the typology of industrial relations systems to contribute to the cross-country analysis of relevant patterns of change from 2008 to 2021, particularly in relation to collective bargaining.
