Identification of conditions for establishing in-house subcontract labor union is an important issue for both labor and management, yet related research is extremely rare. Using Korea Labor Institute's Workplace Panel Survey data for the 3rd ~ 5th year (2009 ~ 2013), this paper examines the determinants of the in-house subcontract labor union establishment by pooled logit and random effects model. Major findings are as follows. First, the increase in the number of workers in the workplace recognized as industrial accidents increased the probability of establishing in-house subcontract labor unions. Second, the welfare policy for indirectly-employed nonstandard workers was not statistically significant. Third, the probability of establishing in-house subcontract labor union was higher in multiple establishments. Fourth, the probability of establishing in-house subcontract labor unions in the public sector is higher than in the private sector. Fifth, the higher the financial performance and the older the business, the higher the probability of establishing in-house subcontract labor unions. Sixth, there was a positive relationship between the ratio of indirectly employed nonstandard workers and establishment of in-house subcontracted unions. Seventh, the favorable labor-management relations were positively correlated with the probability of establishing in-house subcontract labor unions, but they were not statistically significant. The results of this study will provide a clearer framework on how workplace and labor relations characteristics affect the establishment of in-house subcontract labor unions, and can be used as reference material for the related stakeholders. In addition, it can give various implications to the selection and implementation of human resources management and labor relations strategy of the company.
