STORY: Samsung workers began a three-day strike for better pay in South Korea on Monday.

The National Samsung Electronics Union said about 3,000 workers attended a rally near company headquarters, south of the capital Seoul.

It further said Samsung's production operations could be affected, and disputed media reports of low turnout.

Union President Son Woo-Mok:

"What we think is the most important for this strike is to disrupt production, so we've been mainly encouraging those working on the production line to join the strike so they can directly impact it."

The union has demanded increased pay and leave, and equality in the company's bonus system.

Samsung has proposed flexibility in pay and leave conditions, but hasn't yet met union demands.

The tech giant said there was no disruption in production Monday.

Analysts also said low participation and automated production means the strike is unlikely to have a major impact on output.

But it still signals a fall in staff morale at a key point for the chip industry, as tech firms enjoy soaring demand for AI-related gear.

Monday's walkout follows the union's first industrial action last month.

The union said 6,540 workers will take action this week, mostly at manufacturing sites and in product development.

The union has roughly 30,000 members, who make up almost a quarter of the firm's South Korean workforce.
