Unionized workers at Samsung Electronics, staging the biggest labor action in the technology giant’s 55-year history, declared an “indefinite general strike” Wednesday, stepping up pressure over their demand for a pay raise.

After a three-day strike scheduled to come to an end Wednesday, the National Samsung Electronics Union, the largest labor union at the world’s largest memory chipmaker, had planned to stage another five-day strike, starting July 15.

But the union said it changed its plan to go straight to an indefinite strike as the company did not attempt to engage in any dialogue during the three-day strike.
