Job satisfaction is one of the most widely discussed issues in organizational behavior , personnel and human resource management and organizational management. As teaching does require a great deal of thoroughness and commitment, so in teaching it is more important to have mental commitment and loyalty than physical presence. In this study the researchers investigated the present level of job satisfaction among the faculty members of private universities of tertiary level in Bangladesh. Based on a survey, it attempts to gain insights into the satisfaction levels from the perspective of the private university teachers. The study concluded with the facts that faculty members are overall satisfied with their present condition, except the factors like- training facilities, and some physical facilities and distribution of courses. Further it has been found that there is no significant difference between male and female faculty members regarding job satisfaction. As the job itself is not gender bias by nature so it does not play a crucial role for female faculty members while working under masculine culture. The researchers summed up with view that universities may give more attention to motivate and maintain these human resources to make them more contented and to make the most of their effort by ensuring overall excellence of organization.
