NextFin News -- The world's largest chipmaker Samsung Electronics is hurtling toward the largest strike in its history after last-ditch labor negotiations collapsed on Wednesday. Over 48,000 workers —representing more than 60% of the tech giant's critical semiconductor division—will launch a massive 18-day walkout. Driven by the AI boom, the union demands 15% of operating profits, rejecting management's counteroffers. As continuous-run fabs face production shocks, Samsung shares plunged nearly 4% during Wednesday's intraday trading. With global clients fearing severe supply disruptions, South Korean officials are weighing rare compulsory arbitration to contain a potential 30-trillion-won economic blow.
