Workers at South Korean tech giant Samsung Electronics will extend an unprecedented strike over pay and benefits "indefinitely," its labor union said in a statement on Wednesday. This is the first strike by the labor union in Samsung Electronics' entire 55-year history, according to local media. "The company remains committed to engaging in good faith negotiations with the union," Samsung said. The NSEU, which extended the strike saying Samsung management was not keen on holding discussions, asserted the strike had disrupted chip production. Samsung Electronics is the world's largest maker of memory chips, commonly found in consumer devices such as smartphones and laptops.
