While their power is declining, unions and workers remain prominent actors in society. Therefore, there is a need to bring power resource theory back to the analytical forefront in the study of contemporary labour politics and labour market sociology. It provides the analytical perspectives necessary for a comprehensive and historical understanding of labour markets and labour politics. However, this article argues that the original theory developed by Korpi needs to be reassessed and further developed. Revisiting the original theory and reviewing common criticism, the authors argue that power resource theory should pay closer attention to how different types of power resources are mobilised and used and how actors’ interests are shaped during that process. The article seeks to address these issues and thus move power resource theory forward and pave the way for future theorisation.

Germany and Denmark are among the world’s largest exporters of meat products. Two decades ago their labour markets were similar, but since then they have diverged significantly. The industry in Denmark has maintained high wages and good working conditions, while in Germany there has been a rapid growth in precarious employment, with widespread use of subcontracted and posted migrant workers. We argue that the key explanation for this radical difference is the power position of the trade unions, which also affects how employers position themselves. We show how trade union power embedded in the local and sectoral industrial relations systems influences the wages and working conditions in German and Danish slaughterhouses.

Through a cross-national comparative study of local government "best practice cases" of socially responsible procurement in Denmark, Germany and the UK, this article critically examines the role of labour clauses in addressing issues of low wages and precarious work in public supply chains. It provides new insights on the negotiations and outcomes of labour clauses across different stages of the policy process, including implementation and monitoring. The analysis demonstrates the importance of pragmatic alliances of progressive local politicians, unions, and employers in ensuring that socially responsible procurement moves beyond rhetoric, along with supportive national and sectoral employment regimes. Labour clauses can compensate for weak systems of labour market regulation by setting higher standards for outsourced workers, while they play a complementary role in more regulated labour markets by levelling up wages and working conditions to prevailing collectively agreed standards.

Eastern and Central European labour migration following the EU enlargement has significant impact on the Nordic labour markets. This article demonstrates, through sector-based case studies in Denmark, how labour migration influences working condition and wages in two sectors that have so far only been sparsely studied: the agriculture and cleaning industries. The high inflow of labour migrants is used by some employers to bypass and undermine the institutionalized class compromise, by employing EU8/2-workers at lower wages and often without collective agreements coverage frequently combined with below average working conditions. This put strains on the Danish agreement-based model of industrial relations, potentially leading to a more segmented labour market as well as replacement of native, mainly low-skilled workers with EU8/2-workers.

Transnational workers on large-scale construction projects are often poorly included in national industrial relations systems, which results in employment relations becoming trapped in vicious circles of weak enforcement and precarious work. This article shows how Danish unions have, nonetheless, been successful in enacting existing institutions and organising the construction of the Copenhagen Metro City Ring, despite initially encountering a highly fragmented, transnational workforce and several subcontracting firms that actively sought to circumvent Danish labour-market regulation. This is explained by the union changing their organising and enforcement strategies, thereby utilising various power resources to create inclusive strategies towards transnational workers. This includes efforts to create shared objectives and identity across divergent groups of workers and actively seeking changes in the public owners’ attitude towards employment relations.
