Despite the growing body of scholarship on burnout among social justice activists who are working on a variety of issues, from labor rights to queer justice, little attention has been paid to burnout among those whose activism focuses on issues of educational justice. To begin to address this omission and understand what supports might help social justice education activists mitigate burnout and sustain their activism, we analyzed interview data from 14 activists focused on activist burnout and its implications on movements for educational justice. This analysis identified 3 major symptom categories of activist burnout and we gained insights into the "culture of martyrdom" in social justice education movements. These symptoms and the culture of martyrdom, by negatively impacting the health and sustainability of activists, threaten the efficiency and effectiveness of educational justice movements.
