E/C.12/KOR/CO/4 in its national social security system and benefit from welfare services, and ensure the universal birth registration of children, irrespective of the status of the parents. The Committee refers the State party to its statement dated 13 March 2017 on the duties of States towards refugees and migrants under the International Covenant on Economic, Social and Cultural Rights (E/C.12/2017/1). Non-standard forms of employment 28. The Committee remains concerned at the prevalence of non-standard forms of employment, including long-term temporary employment, in spite of the adoption of measures, such as act No. 8074 of 2006 on the protection of fixed-term and part-time workers. Moreover, the Committee remains concerned that in order to minimize their labour costs and transfer accident risks, large companies resort to practices involving subcontracting, “dispatched labour” and the recruitment of individual contractors that deprive workers of the protection of labour rights (art. 7). 29. The Committee recommends that the State party take effective measures to curb abuse of the forms of employment that do not fully protect workers’ rights. In that regard, the Committee recommends that (a) the labour legislation cover all categories of workers, including those who are working under the regime of subcontracts or dispatched labour, or who are recruited as individual contractors; (b) legislative and regulatory measures be taken to fully implement Supreme Court ruling 2007 Doo 1729, outlawing unreasonable non-renewal of contracts, including deterrent penalties for contraveners; and (c) labour inspections effectively monitor abuse of non-regular forms of employment. Coverage of the labour and social security legislation 30. The Committee is concerned that sectors such as agriculture, fisheries and domestic work, where workers are exposed to unfair and unfavourable conditions of work, are excluded from the labour standards act and other legislation protecting the right to just and favourable conditions of work and the right to social security (arts. 7 and 9). 31. The Committee urges the State party to expand coverage of the labour standards act and other laws protecting workers’ right to just and favourable conditions of work and the right to social security to all sectors of the economy. Moreover, the Committee recommends that any distinct legislation applicable to specific sectors, such as agriculture, fisheries and domestic work, do not provide for a lower level of labour rights, but rather address the increased risk of infringement of workers’ rights. The Committee refers the State party to paragraphs 47 (f) and (h) of its general comment No. 23 (2016) on the right to just and favourable conditions of work. Adequate remuneration 32. The Committee remains concerned that, in spite of the recent increase, the minimum wage remains inadequate to enable workers and their families to enjoy a decent living. The Committee is also concerned at the number of workers that are paid below the minimum wage (art. 7). 33. The Committee reiterates its recommendation that the State party ensure that the minimum wage is at a level which would enable workers and their families to enjoy an adequate standard of living. It also recommends that the minimum wage be applicable in all sectors and enforced through labour inspections and dissuasive penalties. Gender wage gap 34. The Committee is concerned that the gender wage gap has not narrowed in spite of the measures taken by the State party (art. 7). 5
