This study examined the ethical leadership and workplace well-being of teachers in public secondary schools in the Caraga North District, Division of Davao Oriental. A non-experimental quantitative research design utilizing the correlational method was employed. The respondents of the study consisted of 132 public secondary school teachers selected through universal sampling. Data were analyzed using the mean, Pearson r, and regression analysis. The findings revealed that both the ethical leadership practices of school heads and the workplace well-being of teachers were at a high level. Results further showed a significant relationship between ethical leadership and workplace well-being, with the domains of ethical leadership exerting a significant influence on teachers’ workplace well-being. Based on these findings, it is recommended that public secondary school teachers participate in seminars and training programs organized by the Department of Education (DepEd) to enhance professional growth and instructional competence. Likewise, schools may strengthen professional development initiatives aimed at building teacher capacity, thereby providing more rigorous and well-supported educational opportunities that improve academic practices and student learning outcomes.
