The National Samsung Electronics Union (NSEU) was holding a three-day national strike when the announcement was made.
The union said that it took this choice because management had not indicated that it would engage in negotiations over its requests.
The NSEU, which in South Korea represents almost 25% of Samsung Electronics employees, said that its protests had hampered production. Samsung refutes these assertions.
“Samsung Electronics will make sure there are no manufacturing line interruptions. The business is still dedicated to holding sincere talks with the union,” the company stated.
However, the labor group stated: “The company has no intention to engage in a dialogue even after the first general strike; thus, we declare a second general strike starting on July 10th, lasting indefinitely.”
Approximately 6,500 workers have participated in the walkout thus far, according to the NSEU, which is urging more of its members to join the work stoppage.
Regarding the number of employees who had joined the strike, a Samsung Electronics representative declined to say.
