Leadership in general is still perceived as individualistic, masculine and hierarchical. Despite fighting against discrimination and for social justice, third sector organizations are themselves often places of entrenched privilege and limited diversity. Leaders with lived experiences draw on their first-hand experience of social issues and/or injustices and attempt to tackle those problems through their work. They represent a diversity of backgrounds, experiences and capabilities that challenge the homogeneity of third sector leadership. Following critical leadership studies this thesis draws from the standpoints of lived experience leaders to offer new, intersectional perspectives on leadership and to expand and diversify understandings of what it is to lead in third sector organizations. The focus of this thesis’s exploration is the experiences and perceptions of 10 individuals who hold or have held leadership positions within third sector organizations in the UK and Germany. Through the analysis of semi-structured interviews, a phenomenology of lived experience leadership is explored. Drawing from feminist standpoint theory, attention is paid to what lived experience leaders think about leadership generally and lived experience leadership in particular, as well as their perspectives on the systemic leadership structures they exist within and challenge. It is found that lived experience leaders acknowledge ‘traditional,’ ‘mainstream’ concepts of leadership and see their own leadership styles and approaches as distinct from these leadership norms. Their approaches and understandings challenge typical leadership constructions and, strongly influenced by their own lived experiences, promote political self-organization, activism and a socio-economic empowerment of people with lived experiences in order to unravel current social power structures and promote social change. With these key findings, the paper suggests further research to test and expand on the conclusions drawn. Ensuring that leadership positions are accessible to all should be a priority for future development of third sector organizations and beyond. Further research should therefore explore how lived experience leadership can help to gain insights about how to remove barriers to leadership positions efficiently.
