PANGYO, South Korea – Kakao, the operator of South Korea's dominant messaging platform, is facing renewed industrial action as its labor union launched a full-day strike on June 29, 2026. Dubbed "Logout Day," the collective action follows a breakdown in salary and performance-based compensation negotiations that have remained deadlocked for two months.

Escalation of Industrial Action

The unionized workforce, representing five key entities—Kakao headquarters, Kakao Pay, Kakao Enterprise, DK Techin, and XL Games—organized the strike by having members take full-day annual leave or time off, effectively logging out of all internal work systems. This follows a landmark four-hour partial strike held on June 10, which marked the first such walkout in the history of the company.

Industry analysts estimate that the number of participants for this second wave of action could reach up to 3,000 employees, including staff across the various affiliates. Unlike the previous strike, which was limited to a few hours, this "Logout Day" involves a complete cessation of work for the entire day, raising concerns about potential impacts on emergency response capabilities.

The Core Dispute: Profit Sharing vs. Corporate Sustainability

The primary driver of the conflict is a deep disagreement over the company’s performance-based bonus structure. The union is demanding a performance bonus equivalent to approximately 10 million KRW per person, which they state represents about 13% to 14% of the company's operating profit from the previous year. Furthermore, the union has taken issue with management’s proposal to include Restricted Stock Units (RSUs) worth 5 million KRW as part of the bonus pool, arguing that these should be provided as a separate benefit rather than a substitute for cash incentives.

Management, however, maintains that the union’s demands are financially unsustainable. "The compensation plan demanded by the union is at a level that would significantly burden company management," a Kakao official stated, emphasizing the need to consider future investment capacity and shareholder value when determining bonus levels.

Service Stability Amidst Labor Unrest

Despite the escalation in labor-management tensions, Kakao has assured users that core services, including the flagship KakaoTalk messenger and Kakao Pay, remain operational. The company has implemented a "real-time response system" to ensure service stability and minimize any potential inconvenience to customers.

Given that much of the service maintenance and operational infrastructure at Kakao is highly automated, the first strike on June 10 resulted in no significant service disruptions. However, the company remains on high alert, with officials stating that they will continue to engage in dialogue with the union to find a mutually acceptable resolution.

A Broader Context of Discontent

The strike at Kakao reflects broader grievances within the South Korean tech sector regarding employment security and the fairness of profit-sharing models. Beyond the bonus dispute, some employees have expressed growing distrust toward management, citing recurring issues such as the controversial sale of affiliates and a perceived lack of clear vision for the company's future business units.

As of the morning of June 29, the union has not announced plans for offline rallies or public statements, focusing instead on the impact of the "Logout" maneuver. Both labor and management now face pressure to bridge their differences to prevent further disruptions and restore internal stability within one of South Korea's most influential technology conglomerates.
