This study explores the influence of team mindfulness on nurses' presenteeism. The mediation effect of perceived empathic concern and perceived insider status and the moderating effect of organisational formalization are assessed. Nurses are prone to presenteeism. Few studies have explored the influence of the organisational environment on nurses' presenteeism. Studies that consider organisational, work-related and person-related factors on the decision-making process influencing nurses' presenteeism are scarce. Using a cross-sectional survey, data from 396 nurses were gathered from three time points and multiple regression analyses were used to test each hypothesis. (a) Team mindfulness reduces nurses' presenteeism. (b) Both perceived empathic concern and perceived insider status mediate the relationship between team mindfulness and nurses' presenteeism. (c) Organisational formalization exerts a positive moderating effect on the relationship between team mindfulness and perceived empathic concern. Team mindfulness reduces nurses' presenteeism through affective (perceived empathic concern) and cognitive (perceived insider status) sensemaking paths. Organisational formalization is a situational factor to improve the effectiveness of team mindfulness. Nurse managers need to devote themselves to cultivating team mindfulness, building an atmosphere to promote perceived empathic concern and perceived insider status, and promoting a formal organisational structure.
