ABSTRACT This article examines the external and organizational factors behind the coalition dynamics of two labour unions representing different types of employment contracts – temporary and permanent – that led the 2007 Irregular Workers Movement in South Korea. Drawing on semi-structured interviews, video footage, newspapers and internal document data, we find that while political opportunities drove the two unions to come together, broad alliances that formed around the coalition on the issue of job security for irregular workers caused the union of predominantly regular workers to become marginalized. Organizational differences that initially seemed complementary prevented a shared identity from forming despite collective strikes and became a source of resentment. The varying progress of negotiations not only reduced the benefits of claims coordination and collective action but also invoked otherness between the two unions. Lack of trust and recognition did not allow for even a loose relationship of cooperative differentiation.

当联盟瓦解时：两个韩国工会在工作不稳定的时代建立团结的案例

摘要 本文研究了代表不同类型的雇佣合同（临时和永久）的两个工会的联盟动态背后的外部和组织因素，这导致了 2007 年韩国的非正规工人运动。利用半结构化访谈、录像、报纸和内部文件数据，我们发现虽然政治机会促使两个工会走到一起，但围绕非正规工人的工作保障问题形成的广泛联盟导致了工会主要是正式工人成为边缘化。尽管集体罢工，最初看似互补的组织差异阻止了共同身份的形成，并成为了怨恨的根源。谈判的不同进展不仅减少了索赔协调和集体行动的好处，而且还引发了两个工会之间的差异。缺乏信任和认可甚至不允许合作差异化的松散关系。
