The Korean Confederation of Trade Unions will participate in a government-proposed one-point social dialogue on a semiconductor megacluster bill, marking its return to tripartite labor talks after six years. KCTU opposes proposed exemptions from South Korea’s 52-hour workweek limit and related overtime, night and holiday allowances for managers and researchers among the top 3% of income earners. The government is also considering extending the selective working hour system’s calculation period from one month to six months in designated megaclusters. Earlier proposals linked to the Honam Semiconductor Cluster included exemptions for research and development personnel and extending fixed-term employment from two to four years. Business groups want work-hour rules applied nationwide and say power, water and military airfield relocation remain more urgent obstacles. The government and ruling party aim to introduce the bill by the end of September, although labor participation does not indicate agreement.
