The purpose of this study was to examine differences in career-related variables, such as career commitment and career satisfaction, based on employment status (temporary vs. permanent employees) and job type (professional vs. nonprofessional employees). With a sample of 302 employees working in information technology companies in Korea, it was hypothesized that among the professional employees there would be no significant differences in career-related variables between temporary and permanent employees, whereas among the nonprofessional employees temporary employees would have lower scores of the career-related variables than permanent employees. The hypothesis on career commitment was supported, whereas the hypothesis for career satisfaction was only supported for the nonprofessional employees. These findings suggest that professionalism can increase career commitment for temporary employees. The implications, limitations of the study, and the need for future studies are discussed.
