The purpose of the study was to analyze a series of factors that influence the early careers’ voluntary
turnover intention in small and medium-sized corporations. First, we explored the influential factors for
job and workplace-related variables and their effects. Next, we investigated the organizational culture and
environmental factors that affected the careers’ turnover as the mediating variables. Subjects are the early
careers who were 2-3 and 4 years graduates and had worked in small and medium-sized corporations
under 300 employes. Finally, 807 subjects were analyzed. The results were as follow. First, educational
mismatch, job satisfactions, work type, and wage level of early careers in small and medium-sized
corporations have affected their turnover. The level of turnover of early careers became lower when their
job satisfaction was high and wage level was higher. Second, organizational culture and environmental
variables, including communication, human relationship, work environment, and personal development
mediated the turnover subjectively. Although the job satisfaction was lower and organizational culture
and environment variable was high, their turnover intention became lower. Finally, other mediating
variables have no effects on turnover intention, including job type and wage level. We suggested the
necessity of education and training for early careers in small and medium-sized corporations and it’s
expected to decrease their rates of turnover.
