This study proposed and tested corresponding sets of variables for explaining voluntary organizational versus occupational turnover for a sample of medical technologists. This study is believed to be the first test of the Rhodes and Doering (1983) occupational change model using occupational turnover data. Results showed that corresponding job (occupational) satisfaction and intent to leave organization (occupation) variables were each significant for explaining subsequent organization (occupation) turnover. Job insecurity was found to be a significant correlate for organizational turnover while work exhaustion was found to be a significant correlate for occupational turnover. Study limitations and directions for future research are discussed.
