Work agreements in positive law are regulated in Law no. 13 of 2003 concerning Manpower and Decree of the Minister of Manpower and Transmigration No. 100/MEN/IV/2004. Work agreements are divided into 2 (two) types, namely Work Agreements for an Unspecified Time (PKWTT) and Agreements for a Specific Time (PKWT). In this case, the author conducted research on legal protection carried out by the DIY Oversight Office of Manpower and Transmigration for Workers in the outsourcing company PT MEDIA, Sleman Regency. Outsourcing company PT MEDIA Sleman Regency in practice uses PKWTT and PKWT, but what is widely used is PKWT. The implementation of PKWTT is quite good with the fulfillment of workers' rights in accordance with labor laws. However, the implementation of this PKWT is a problem, because workers are not given their rights in accordance with applicable law. To anticipate discrepancies in the regulations contained in the manpower law and their implementation and to provide legal protection for workers/laborers as well as companies/employers, the government guarantees by providing supervision through the government, in this case represented by the local Manpower and Transmigration Office.
