This study examined occupational stress and effectiveness among senior secondary school teachers in India. The researchers found that less effective teachers, both male and female, reported higher levels of occupational stress than more effective teachers. Female teachers experienced more stress than male teachers, with 90% of female teachers found to be stressed. Higher occupational stress was correlated with lower teaching effectiveness. The four main sources of occupational stress identified were role conflict, role ambiguity, poor interpersonal relationships, and heavy workload. The study suggests addressing sources of stress in order to improve teacher enthusiasm, accountability, and job satisfaction.
