In this article, we review and assess research on the role of trade unions in labour markets and society, the current decline of unions and union revitalisation. The review shows three main trends. First, trade unions are converging into similar strategies of revitalisation. The ‘organising model’ has spread far beyond the Anglo-Saxon countries and is now commonplace for unions as a way to reach new worker constituencies. Thus, even in ‘institutionally secure’ countries like Germany and the Nordic countries, unions are employing organising strategies while at the same time trying to defend their traditional strongholds of collective bargaining and corporatist policy-making. Second, research has shown that used strategies are not a panacea for success for unions in countries that spearheaded revitalisation. This finding points to the importance of supportive institutional frameworks if unions are to regain power. Third, especially in Anglo-Saxon countries, unions are building external coalitions with other social movements, including across borders, to compensate for the loss of power resources that were tied to national collective bargaining and policy-making. Research has shown that unions, even in adverse institutional contexts, can be effective when they reinvent their repertoires of contention, through political action or campaigning along global value chains.

The widespread decline of trade unions and the emergence of various alternative forms of worker voice and representation have posed a challenge to the field of industrial relations and generated significant rethinking of the future directions for this field of study. In this article, we examine how well industrial relations meta-theories, when combined with efforts to build middle-range theories, provide distinctive explanations and different predictions for the alternatives that have emerged to date to fill the void. We propose new directions for theory and research that expand the range of actors or institutions that shape employment relations and include social identities outside of the employment relationship as the basis for mobilizing collective actions and voice. Finally, we suggest using these theoretical arguments to test among alternatives as a means of revitalizing and reshaping industrial relations as well as carrying forward the problem-solving norms that have characterized the field since its inception.

This article develops a new analytical framework to account for institutional change in vocational education and training (VET) systems. Trajectories of institutional change are typically explained using one of two perspectives on institutional contention. First, the Varieties of Capitalism-approach highlights positive efficiency effects from coordination between companies on skill formation. Second, a historical institutionalist approach focuses on positive political feedback effects from the governance of VET institutions. We propose adding a third dimension of institutional contention related to what role VET should play in fostering greater socio-economic equality. Employing this three-dimensional framework enables a more fine-grained analysis of gradual forms of institutional change and greater appreciation of the ways in which political struggles over the configuration of the three dimensions drive institutional reform. The argument is supported by analyzing the trajectory of institutional change in the Danish VET system in the post-war period.

Often neglected in flexicurity studies is the question of how collective bargaining contributes to the development of flexicurity, despite the continued resilience of this form of regulation in many European countries. The article compares sector-level bargaining and flexicurity in the printing and electrical contracting industries of Denmark, Spain and the UK to assess this link. In line with prior research, the article finds that Danish agreements contribute significantly to flexicurity. Somewhat against conventional expectations, however, are findings in the UK and Spain. In the UK, agreements contribute significantly despite a hostile context for collective bargaining. In Spain, due to the heavy influence of legislation the contribution is more modest but nevertheless notable. This overall finding gives strong evidence for the proposed link. The article goes on to discuss if a positive contribution is facilitated by certain institutional and relational conditions.
