Drawing from social learning theory and the conservation of resources theory, this study examines the relationships between authentic leadership, collective mindfulness, collective thriving, and prosociality in hotel workplaces. Data from 86 hotel units with a total of 354 full-time frontline employees were used to test the research hypotheses via structural equation modeling. As anticipated, statistical results revealed that authentic leadership is positively related to collective mindfulness and collective thriving; collective mindfulness is positively related to collective thriving; and collective thriving is positively related to prosociality (helping behavior and proactive customer service behavior, respectively). This study links Buddhist culture to Western management theory and highlights that collective mindfulness partially mediates the relationship between authentic leadership and collective thriving.
