The dynamics of union-management collaboration during postmerger integration

Collaboration between unions and management may facilitate postmerger integration, however collaboration can also be time-consuming and challenging. Using a qualitative case study, we examined union–management collaboration in the integration of two Norwegian firms. The integration was split into two processes, involving different business units. While both processes were designed according to similar principles of collaboration, we observed the emergence of two diverging integration trajectories. Whereas the first process was characterized by a virtuous cycle of trust and constructive collaboration that facilitated integration, the second process turned into a vicious cycle of mistrust and conflict, causing disruption, and impeding integration. Based on our inductive analysis, we identify four distinctive features characterizing the emerging mode of collaboration. We develop a model to illustrate the dynamics of union-management collaboration in postmerger integration. These findings expand the current understanding of merger and acquisition (M&A) dynamics to include a broader set of actors and potential conflict factors in the integration process. Furthermore, our study suggests that collaborative integration processes require careful management while also potentially posing challenges for unions, particularly in the context of historical conflicts.
