Samsung workers to strike ‘indefinitely’ posing risk to global tech

Samsung Electronics Co.’s largest labor union of more than 30,000 workers declared an indefinite strike, a surprise move that raises the risk of production disruptions at the world’s largest memory chipmaker.

The union’s call for a general strike sharply escalates a dispute with South Korea’s biggest company. Thousands of workers rallied earlier this week outside Samsung’s chipmaking complexes south of Seoul to kick start what originally was a three-day walkout demanding better pay.
