Towards ‘multi-collar’ unionism: Cases of trespassing professionals in Norwegian industrial relations

This article discusses the changes in workers’ identity as blue-collar or salaried staff with respect to changing work content due to new models of industrial systems. Within these new industrial models, traditional blue-collar work is moving into areas of work previously held solely by salaried staff. This article argues that the merging of work content will cause a process of identity-mergers, a process calling for increased collaboration between blue-collar unions on the one hand, and salaried staff unions on the other. Reporting on four company cases, the authors argue that this process is caused both by labour unions’ efforts to increase workers’ motivation in work, as well as by market demands generating new models of industrial production. The authors conclude that the models of industrial relations must change so as to encompass cross-union collaboration and the diversity of professions.
