PurposeThe fundamental challenge for project management is dealing with people and their feelings. While there has been sporadic attention to the importance of emotions in project work, project management practices tend to neglect the role of emotions and emotional reflexivity. The authors use a symbolic interaction framework to present an in-depth exploration of emotions and emotional reflexivity in projects.Design/methodology/approachEmpirical data was gathered in 19 semi-structured interviews with diverse project managers to assess their experience of emotion (15 male, 4 female, early 20s to late 50s, 3–38 years of expertise). Transcribed interviews were thematically analysed using a sociology of emotions informed, grounded theory, interactional framework.FindingsThe data revealed that emotional states are framed by factors specific to project management, including organisational change, project constraints and dealing with stakeholders. Explicitly managing emotions improved team engagement and project performance by acting as a catalyst for engaging in reflective practice and intuitive decision making.Practical implicationsGiven the widely held misconceptions of emotion as maladaptive, project management education must focus on empathy in communication and leadership if practitioners are to master valuable soft skills. Techniques for emotional reflection and learning feeling lessons must be incorporated into practice.Originality/valueThe authors contribute to the emerging understanding that emotions matter in project management. The authors demonstrate the centrality of emotions in projects and the substantial impact they have on the wellbeing of practitioners and staff. Emotional reflexivity in practice, which is widely acknowledged yet tends to be ignored, is an essential part of the project manager's toolkit.
