"International Covenant on Civil and Political Rights" and "International Covenant on Economic, Social and Cultural Rights" (hereinafter "two Covenants") were the Realization of the "Universal Declaration of Human Rights" adopted by the United Nations General Assembly in 1948. However, after the adoption of Resolution 2758 in 1971 by the Assembly, with the representative seat taken away, Republic of China has been unable to participate in the activities of the United Nation thereafter and which made the ratification process of the two Covenants delayed for 42 years until its completion in 2009.Although the two Covenants possess its legal significance back in 1960, the protection thereof concerning the labor is relatively oversimplified and outdated from present perspective. On the other hand, standards and rules contained in the International Labor Organization's Conventions (hereinafter ILO Conventions) and the Recommendations become more and more prominent to protect the labor's right nowadays. Therefore, the ratification of the two Covenants can only make little contribution to ROC's Labor Law despite its political significance. Yet, this article is aimed at analyzing the 8 key issues concerning the protection of labor force in the two Covenants and its connection with the ILO Conventions and Recommendations to make a brief review of the current rules concerning labor protection in our domestic legal system.
