Clinicians regularly work as teams and perform joint actions that have a great deal of moral significance. As a result, clinicians regularly share moral responsibility for the actions of their teams and other clinicians. In this paper, we argue that clinicians are exceptionally susceptible to a special type of moral luck, called interpersonal moral luck, because their moral statuses are often affected by the actions of other clinicians in a way that is not fully within their control. We then argue (...) that this susceptibility partly explains why a conscientious clinician has reason to avoid participating in unvirtuous healthcare teams. We also argue that this susceptibility partly explains the special systems of entitlements that characterize healthcare teams and set healthcare teams apart from other teams of workers. (shrink)
