Industrial relations and sectoral interests: Comparing extension of collective agreements in construction and shipyards in Norway
比较挪威建筑业和造船业中，雇主和工会如何因产品市场竞争和跨境流动性的差异，对集体协议扩展采取不同立场，解释为何造船业雇主反对而建筑业雇主支持扩展。
This article expands knowledge on the (inter)sectoral dimension of industrial relations, specifically how sectoral differences in product market competition, scope and mobility have shaped organized actors’ regulative responses to the rising cross-border labour and services mobility in the post-2004 EU/EEA Single Market. We compare how organized employers and labour in the (non-tradeable) construction sector and the (tradeable) shipbuilding sector approached the extension of collective agreements and navigated EU posting rules in wake of the 2004 enlargement. Showing how organized employer interests in tradeable and non-tradeable sectors are oppositely affected by enhanced cross-border mobility, competition and national re-regulation of migrant workers’ rights, we explain why shipbuilding employers acted as antagonists while organized construction employers in alliance with their union counterparts served as protagonists in the strife over extension.
