The present study aims at finding out the relationship between occupational stress and mental ill health among the teachers. Occupational Stress Index was used to collect data from a sample of 100 teachers. Statistical techniques such as mean, standard deviation, t test and coefficient of correlation were employed for the analysis of data. Analysis of occupational index scores revealed that teachers are moderately stressed. It is found through correlational analysis that occupational stress is significantly related with anxiety, depression, somatic symptoms and social dysfunction. t-tests indicated significant differences between high and low occupational stress groups of teachers with relation to dimensions of mental ill health.
