In addition to guarding national frontiers, some border patrol officers also escort illegal immigrants abroad. This article analyses this work from an interest in officers’ (moral) experiences and how these relate to the circumstances in which they work, such as occupational culture, policy and procedures. Therefore, the notions of dirty work and moral injury are used as conceptual frameworks, and 14 Dutch escort officers were interviewed about their experiences. This article adds to dirty work analyses by developing an understanding of how workers’ experiences relate to both formal and moral legitimacies and a possible tension between the two. In addition, it extends the literature on moral injury by describing context-dependent forms of impact that escape clinical diagnoses. Theoretically, this article shows that the occupational resources that are elsewhere seen as tools for navigating ‘necessary evils’ can in fact hide the impact of this kind of work.
