Collegiality is considered a hallmark of professionalism and involves specialization, equality, and leadership based on profession. Traditionally, within a profession, collegiality is treated as given and dealt with intra-professionally. This article, in contrast, studies collegiality as institutional work within the organizational context. We analyse how professionals and managers in a highly professionalized and institutionalized organization perform collegiality as institutional work. Interview and observational data shed light on collegiality in the practices of pastors in the Church of Norway. The findings highlight collegiality as a cultural ideal and a process of work beyond a mere governance structure. Collegial meetings constitute structural work that signals the intersection of conceptual work (theology) and operational work (daily challenges), facilitated by relational work. This article shows how collegiality constitutes institutional work that not only maintains the pastor profession as an institution but also gradually adapts it in response to external demands and strengthened management.
