LS Cable & System has ended a 37-year no-work-stoppage record, with its Federation of Korean Trade Unions-affiliated union holding a rally and staging partial strikes at plants in Gumi and Donghae. Workers are seeking a 6.5% base-pay increase and performance compensation equal to 15% of operating profit, while management has offered a 4% raise and a fixed bonus of 8.5 million won. The dispute follows record results driven by demand from artificial intelligence data centers. Labor action has also intensified at POSCO, HD Hyundai Heavy Industries, Hanwha Ocean and Samsung Heavy Industries, as chip-sector payouts raise expectations while steelmakers face oversupply and weaker profitability. Settlements before Chuseok are viewed as a key test, although analysts say wider participation by subcontractors would be needed for full-scale production disruptions.
