Unionized financial workers in South Korea have voted overwhelmingly to stage a one-day nationwide strike later this month, demanding better working conditions and pay.

The Korean Financial Industry Union (KFIU), representing employees across private and state-run banks as well as financial institutions, announced Tuesday that 95 percent of its members supported the strike. The walkout is scheduled for September 26. The union is calling for wage increases, the introduction of a 4.5-day workweek, more hiring, and an extension of the retirement age. The KFIU is affiliated with the Federation of Korean Trade Unions, one of the country’s two major umbrella labor organizations.

At the same time, tensions are brewing within South Korea’s tech sector. Unionized workers at Samsung Electronics submitted a letter to Chairman Lee Jae-yong demanding greater transparency in the company’s bonus system. They criticized Samsung’s reliance on the economic value added (EVA) framework, which they argue lacks fairness and can result in no bonuses despite strong operating profits.

The push comes after SK hynix reached a tentative agreement with its labor union on Monday to allocate 10 percent of its annual operating profit to a profit-sharing bonus program. The deal also scrapped a previous ceiling that capped payouts at 1,000 percent of basic pay, signaling a more worker-friendly approach.

Samsung employees stressed that adopting a more transparent and performance-linked system is essential to rebuilding trust. They noted that while competitors like SK hynix are moving toward equitable models, Samsung risks falling behind in worker satisfaction.

Financial markets reacted positively, with Samsung Electronics stock rising 2.22 percent to 69,100 won at Tuesday’s close, while SK hynix shares climbed 1.76 percent to 260,500 won.
