The article identifies how tensions between different levels of worker solidarity helped shape the possibilities of collective action in automobile and related sector trade unions in Argentina. It advances the framework proposed by Morgan and Pulignano in two ways. First, it highlights the interrelation of both the complementarities and the tensions between different solidarity practices. Second, it extends the understanding of how these solidarity practices connect the workplace and community. The contribution is based on thematic analysis of interviews with trade union leaders, representatives and activists that shed light on solidarities produced, as well as tensions and complementarities between them. This is contextualised by the impact of crisis in the automobile sector after 2015, showing how increased worker vulnerabilities affected emergent solidarities. Overall, the article demonstrates the significance of these dynamics for understanding the continued resilience and limitations of trade unions in Argentina and beyond.

这篇文章确定了不同层次的工人团结之间的紧张关系如何帮助塑造阿根廷汽车和相关行业工会集体行动的可能性。它以两种方式推进了 Morgan 和 Pulignano 提出的框架。首先，它强调了互补性的相互关系和不同团结实践之间的紧张关系。其次，它扩展了对这些团结实践如何将工作场所和社区联系起来的理解。该贡献基于对工会领导人、代表和活动家访谈的专题分析，这些访谈揭示了所产生的团结，以及他们之间的紧张关系和互补性。这与 2015 年后汽车行业危机的影响有关，显示工人脆弱性的增加如何影响紧急团结。总体而言，本文展示了这些动态对于理解阿根廷及其他地区工会的持续弹性和局限性的重要性。
