The walkout by the National Samsung Electronics Labor Union will begin on Thursday, August 15 (Liberation Day), and continue through Sunday.
This action comes two weeks after the union ended its 25-day strike on August 1, transitioning to a long-term strategy that includes partial stoppages to press their demands.
During the strike, Samsung's largest union, representing more than 30 percent of its total workforce, will refuse holiday work and all flexible schedules.
Despite its short duration, the union expects the strike to have a significant impact on the company.
The timing was chosen strategically, as office staff cannot easily replace production line workers during this period, a union representative stated during a YouTube live broadcast.
Management said that it will strive to prevent production disruptions and adhere to the principle of "no work, no pay" for striking employees.
The company added it will continue dialogue with the union.
