While inter-organizational coordination among firms in networks has become a widespread phenomenon and the governance of inter-organizational networks has garnered considerable attention in the management literature, the repercussions of the network form for managing and organizing work remain a considerable gap in the literature. Building on Gittell’s concept of relational coordination, we explore the inter-organizational work collaboration in four German airports’ ground handling operations. By zooming-in on ramp agents’ boundary spanning work role, our comparative study illustrates whether and how a collaboration in inter-organizational work processes is brought about in practice. Our findings reveal the various practices ramp agents deploy in order to handle the tensions emerging from divergent organizational jurisdictions and the requirements for collaboration. We also illuminate how the field-level context influences inter-organizational collaboration by setting conditions such as workload and time restrictions in distributed service delivery.
