Differences and Determinants of Job Satisfaction by Employment Type

고용형태별 직무만족도 차이 및 결정요인

This study analyzed differences and determinants of job satisfaction by employment type using the Korean Labor and Income Panel Data (KLIPS) (5th~13th) and obtained the following results. First, it was found that the job satisfaction of regular employees was significantly higher than that of non-regular employees and, as a result of analyzing job satisfaction by subdividing various types of employment within the non-regular employment category, 'temporary work' was found to have the highest satisfaction, while 'long-term non-regular work' had the lowest. Further, as a result of analyzing the differences in job satisfaction by the method of career choice, it was found that job satisfaction in the case of choosing a job voluntarily was higher than that in the case of choosing a job involuntarily. Second, as a result of analyzing the determinants of job satisfaction by employment type, all variables in regular employment were found to have statistically significant effects on job satisfaction, which is a dependant variable, whereas non-regular employment was found to have a limited effect only depending on the employment type. In case of the determinants of job satisfaction according to the method of career choice, they were found to have statistically significant effects on all variables except for the career variable in the group that chose employment voluntarily, whereas they were found to have significant effects on some variables only such as gender and wage, etc., in the group that chose employment involuntarily. Therefore, it is more suitable to analyze job satisfaction by subdividing it by employment type rather than dividing it into regular employment and non-regular employment, although the method of career choice (voluntary/involuntary) also needs to be considered.

본 연구는 한국노동패널데이터(5차~13차)를 사용하여 고용형태별 직무만족도 차이 및 결정요인을 분석하였으며, 그 결과는 다음과 같다. 첫째, 정규직이 비정규직에 비해 직무만족도가 유의미하게 높은 것으로 나타났으며, 비정규직을 고용형태별로 세분화하여 직무만족도를 분석한 결과, 비정규직 내에서는 한시적 근로가 가장 높았으며, 장기임시직이 가장 낮았다. 그리고 직업선택 방식에 따른 고용형태별 직무만족도 차이를 분석한 결과, 자발적으로 직업을 선택한 경우가 비자발적으로 직업을 선택한 경우에 비해 직무만족도가 높았다. 둘째, 고용형태별 직무만족도 결정요인을 분석한 결과, 정규직은 모든 변수가 종속변수인 직무만족도에 대해 통계적으로 유의미한 영향을 미치는 반면, 비정규직은 고용유형에 따라 제한적으로만 영향을 미치는 것으로 나타났다. 직업선택 방식에 따른 직무만족도 결정요인의 경우, 자발적으로 직업을 선택한 그룹은 경력변수를 제외한 모든 변수가 통계적으로 유의미한 영향을 미치는 반면, 비자발적으로 직업을 선택한 그룹은 성별, 임금 등 일부변수에서만 유의미한 영향을 미치는 것으로 나타났다. 따라서 고용형태별 직무만족도를 분석할 시에는 정규직과 비정규직으로만 구분하는 것보다 고용형태별로 세분화하여 분석하는 것이 더 의미가 있으며, 직업선택 방식(자발적/비자발적) 또한 고려될 필요가 있다.
