현장실험을 통해 분석한 비정규직의 정규직 전환에 따른 직무태도 변화에 관한 연구

This study is an empirical analysis of whether job attitudes improve as expected when non-regular workers are converted to regular workers. Theoretically, there may be a controversy over whether the transition of non-regular workers to regular jobs necessarily improves job attitudes such as job satisfaction and organizational commitment. According to the social comparison theory as an example, former non-regular workers were compared themselves with non-regular workers inside and outside the organization who performed similar jobs because they were virtually incapable of being converted to permanent workers. However, after the transition to regular workers, their reference group may be changed to existing regular workers, not the non-regular workers anymore. As a result the, job attitudes may fall because of this change in reference group. To analyze the argument above, this study measured the job satisfaction and organizational commitment of non-regular workers who were converted to regular workers at Seoul A corporation under Seoul Metropolitan City. To measure the job satisfaction and organizational commitment, two surveys were conducted respectively before and after transition of non-regular workers to regular workers in the corporation in March through June 2018. In addition, in order to increase the validity of the research results, the control group of existing regular workers was set and surveyed simultaneously. To verify the hypeses, paired t-test and DID test were used in the analysis. The results show that the transition to regular employment has increased job satisfaction for non-regular workers. But the change was not strongly significant as expected by the government and by the scholars who support the transition to regular workers. The results of the study also show that the existing regular workers lower their job attitudes when the experimental group of non-regular workers changes their job status from non-regular to regular employment. This result was interesting because it is expected that the job attitude of control group would not change at all because their physical aspect of working conditions does not change. In the theoretical review of this study, the social comparison theory predict that job attitudes of experimental group may not be necessarily improved or even lowered because the group changes its reference from non-regular to regular workers after the transition. This prediction was supported by the empirical analysis of this study. Of course, this empirical study needs a caution to generalize the results because the study analysed only a sample of specific job group of workers at a public organization in Seoul. Also, the size of control group is not large enough to secure the empirical results. However, this result can be a first step to analyze the real effect of transition of non-regular workers to regular workers in Korean public sector.
