The study investigated the moderating role of perceived organizational support on emotional labour-burnout relation among 323 secondary school teachers in Enugu State, Nigeria. Participants completed the Teacher Emotional Labor Scale (TELS), Survey of Perceived Organizational Support (SPOS), and Maslach Burnout Inventory (MBI). Results showed that surface acting, deep acting, and POS significantly predicted emotional exhaustion. Only deep acting and POS significantly predicted depersonalization whereas surface acting did not. Both the two-way interaction terms between surface acting and POS, and that between deep acting and POS were not significant in predicting either emotional exhaustion or depersonalization.
