Abstract
In the context of nurse shortages and budget constraints in hospitals, retaining skilled nurses is crucial. This paper investigates the impact of supervisor–nurse relationships on engagement, wellbeing, affective commitment and turnover intention for Italian private and public sector nurses. Private sector nurses in Italy were found to be more committed, engaged and had higher perceptions of wellbeing than public sector nurses. Based on these results, public managers need to do more to sustain the motivation of nurses in public sector hospitals.
