This study investigated differences in general values, work values and organizational commitment among 549 private sector, public sector, and parapublic sector knowledge workers. No differences in general values were observed across sectors, although five significant work value differences were revealed: parapublic employees value work that contributes to society more than public servants, who value it more than private sector employees; parapublic employees value opportunities for advancement less than both public and private sector employees; public servants value intellectually stimulating and challenging work more than parapublic employees; and private sector employees value prestigious work more than public servants. Private sector employees displayed greater organizational commitment than the employees in the other two sectors. Overall, the findings suggest only limited value differences among employees of the various sectors. The finding of some work value differences between employees in the public and parapublic sectors suggests that these two groups merit separate consideration in comparative studies such as this one.
