As such, the Commission expressed its opinion to the Minister of Employment and Labor that the Ministry should "ensure in-house subcontracting is not abused as a means to avoid direct employment relationships or to employ agency workers illegally by stating, in accordance with the Supreme Court rulings, the criteria to distinguish legitimate subcontracting and illegal temporary agency work in relevant laws so that if the user-company has the actual right to supervise and manage in-house subcontract workers, the company is found to use illegal agency workers" (November 12, 2012).
