Unionized workers at Samsung Electronics have gone on an indefinite strike, with 6,500 employees walking off the job over pay and working conditions. The strike, led by the Nationwide Samsung Electronics Union, represents a significant escalation in a rare labor dispute that could impact the company's chip business, which is a world leader in the industry. The union, which represents 28,000 workers, has vowed to continue the strike as they have received no response from the company. Samsung, South Korea's biggest private employer, is known for its memory and logic chips, making it a key player in the global tech market. Negotiations between the union and Samsung have been ongoing since January, with the union vowing to stand firm until their demands are met. The union is confident that continued strike action will force Samsung management to come to the negotiating table and reach a resolution.
