In workplace health interventions, engaging management and union decision makers is considered important for the success of the project, yet little research has described the process of making this happen. A case study of a knowledge-transfer process is presented to describe the practices and processes adopted by a knowledge broker who engaged workplace parties in discussions on research on physical and psychosocial factors important for employee health. The process included one-on-one interactions between the knowledge broker and individuals to explain the (...) research, to build trust and credibility, and to explore the applicability of the research to their work (sense making). It also included facilitated group sessions, where the groups explored how the research could solve problems within the workplace (social construction of knowledge). The workplace context offered multiple opportunities that helped and hindered the flow of research. Nevertheless, this intense, sustained, knowledge-transfer intervention noted conceptual, structural, and political knowledge use. (shrink)
