South African organizations operate in a changing environment. The ultimate criterion of organisational effectiveness is whether the organisation survives in its environment. Political, social, technological and economic changes constantly challenge businesses to adopt new approaches in this strive for survival. These challenges affect the roles, and possibly the job satisfaction levels of first-line supervisors and middle-level managers. In this paper, the writer aimed to study and compare job satisfaction levels of first-line supervisors and middle-level managers in the Nelson Mandela Metropolitan area. The effects of job satisfaction, or the lack thereof must be clearly identifiable to the top managers. These can either be positive or negative. In the case of positive effects, managers must strive to maintain the conditions that contribute to the positive effects of job satisfaction. In the study it was observed that middle-level managers scored higher and therefore they had higher overall job satisfaction levels than first-line supervisors. The job satisfaction levels of the first-line supervisors are found to be lower in all the areas that were stated as factors affecting job satisfaction. These areas were the personality job fit, the job content, the job context, the organisational environment and the macro environment. The companies therefore have a task of improving the job satisfaction levels in these areas. The writer recommends that organisations in the Nelson Mandela Metropolitan area take a closer look at the job satisfaction levels of their first-line supervisors. These managers' job satisfaction levels need to be improved from being just satisfactory to being excellent. It is mentioned in the theoretical study that firstline supervisors are very important in organisations, as they are the link between upper management and the employees. Their roles are multi-faceted as they have important functions to fulfil in the operation and ultimately success of the organization.
