Abstract: Stress among workers is becoming more and more prevalent year by year. Stress can lead to other health related problems. Much research has been done to know the causes of stress among workers. In this journal article, academic staff belonging to Higher Learning Institutions in Tanzania was chosen to test weather the causes posed to them were factors causing stress. The objective of this article is to prove that the cause of stress among lecturers is due to demand of staff and support from management. A total set of 55 questionnaires were distributed. The results showed that lecturers of Higher Learning Institutions in Tanzania experience occupational stress. The most common factors that caused occupational stress among lecturers, were lack of support from management, lack of facilities, and feeling work not valued. It is recommended that organisation concerned should help the workers to cope with occupational stress effectively.
