Workers at Starbucks Korea established the company’s first-ever labour union since its entry into the South Korean market in 1999. The union was announced publicly on July 16, 2026, on the Korean Federation of Chemical, Textile and Food Workers’ Unions website and confirmed by Starbucks Korea on July 19, 2026 [1, 2, 3].
The union’s formation came after uproar surrounding Starbucks Korea’s “Tank Day” reusable cup promotion on May 18, 2026. The promotion coincided with the 46th anniversary of the Gwangju uprising, where 165 civilians were killed, which led to widespread public criticism and a sharp decline in sales in the following days [1, 2, 3].
As a result, over 2,000 Starbucks stores across South Korea closed early in June 2026 to conduct staff education sessions on the historical significance of the uprising. The Tank Day controversy also prompted the resignation of Starbucks Korea’s chief executive [1, 2, 3].
Starbucks Korea employs approximately 23,000 people nationwide. The union cited ignored demands for improved workplace conditions and criticized the introduction of burdensome promotional events imposed without worker consultation. The union statement declared, "The time has come for us to assert our rights and re-establish labour-management relations on an equal footing," and expressed a desire to work with sincerity and pride [1].
A company official responded, "We will continue to engage with the labour union in accordance with the relevant laws and regulations," but did not disclose how many employees had joined the union [3].
While union membership among Starbucks employees remains small globally, with only a limited proportion of U.S. stores unionised and represented by Starbucks Workers United, this marks a historic milestone for Starbucks Korea [1, 2, 3].
The Tank Day promotion itself was not directly referenced in the union’s statement. The next key development will be ongoing company-labour discussions as the union seeks to protect worker rights and influence workplace policies.
