The purpose of this study was to examine demographic effects on the satisfaction levels of lecturers from a Singapore public tertiary institution regarding job-related variables. The research findings indicated that demographic variables had an effect on the levels of satisfaction over specific job-related differentials. Satisfaction related to job stress levels increased significantly with being female, age, job position and length of employment; while satisfaction over salary levels rose significantly with being female and job position. Satisfaction with nature of the job was significantly affected positively with job position, academic qualification and length of employment; whereas satisfaction over supervision level decreased significantly with age, marital status, job position and length of employment. Satisfaction with organisational justice rose significantly with age, job position and length of employment, while satisfaction over communication was decreased significantly with age and years of service. These findings have practical implications for the management of the tertiary institution to reexamine their current institutional policies and make the necessary changes to enhance job satisfaction of the academics.
