Incivility is a major concern in healthcare, and it is vital that uncivil behaviour is recognised and addressed. Manifestations of incivility are wide ranging and can take the form of microaggressions, which are difficult to pinpoint but have significant repercussions. Research has demonstrated the negative effects of incivility on staff and patients. Uncivil acts and behaviour can create conflict, reduce performance, affect morale, decrease retention and jeopardise patient safety. The role of nurse managers in reducing incivility and promoting civility includes providing leadership, fostering psychological safety, creating a shared understanding of civil behaviour and managing uncivil behaviour as soon as it occurs. The input of employers is crucial to promote a compassionate and inclusive organisational culture and to support nurse managers to acquire the knowledge, skills and confidence to prevent and reduce incivility.
