The Korean electronics firm Samsung is the world’s biggest manufacturer of memory chips. It also usually outpaces Apple, its main rival, for the production of smartphones. Until a one-day strike last month, Samsung’s workers had never gone on strike throughout its 55-year history as a company, during a period that saw the rise of a strong labor movement in South Korea. Yet after calling a three-day strike last week, on July 10 the National Samsung Electronics Union (NSEU) decided to extend its strike indefinitely as the company continues to dodge negotiations over pay and holidays.
