Abstract: >The study investigated the determinants of occupational stress using gender, self-concept and occupational status as factors. Survey research design was adopted. Sample comprised 100 Bank workers randomly selected from Lagos state, Nigeria. Job Situation Questionnaire (JSQ) was used. Three hypotheses were tested while the student t-test was used for data analysis. Results tested at 0.05 level of significance indicated no significant difference in occupational stress of male and female bank workers and in the research of workers of different occupational status. However, significant difference exists between workers with high self-concept and those with low self-concept. Conclusively, stress effects are greatest among service staff at the bottom of the hierarchy, with least participation in decision-making.
