Employees of Samsung Biologics, a prominent South Korean manufacturer, have overwhelmingly voted in favor of a strike, citing significant concerns over the company’s environmental, social, and governance (ESG) practices. This decision reflects deep-rooted frustrations regarding operational autonomy and what the union describes as a passive approach to labor relations.

Union Vote Breakdown
In a decisive move, union members cast their votes between March 24 and March 29, with an impressive 95.5% supporting the strike. This overwhelming majority signals a collective desire for change that extends beyond wage disputes. Union representatives have pointed out serious issues related to corporate governance, including allegations of unfair labor practices and unauthorized handling of employee personal data.
A Call for Accountability
Jaesung Park, the president of the Samsung Biologics Labor Union, emphasized the stakes involved in this labor action. He articulated that unresolved disputes and compliance failures in the contract development and manufacturing organization (CDMO) sector pose a direct threat to the supply chains of their international clients. The union aims to address these governance issues and foster a more transparent and responsible corporate culture.
Wage Increase Rejection
The union’s discontent was further compounded by the rejection of a proposed wage increase of 4.1% from Samsung Electronics, the parent company. The workers pointed out that Samsung Biologics experienced a remarkable 56.6% increase in operating profits in 2025, suggesting that the suggested raise does not adequately reflect the company’s financial success nor the value of its employees.
Future Steps
As tensions rise, the union has set a timeline for potential action. Unless management presents a credible and autonomous proposal to address their concerns, a rally is scheduled for April 22, leading up to a planned strike on May 1. This timeline highlights the urgency felt by the workers and their commitment to advocating for their rights.
Broader Implications for the Industry
The unfolding situation at Samsung Biologics serves as a microcosm of larger industry trends. As labor relations evolve, companies across sectors must recognize that employee satisfaction and governance structures are critical to maintaining a stable supply chain. Strikes like this one can ripple through the industry, affecting not only the immediate company but also its partners and clients.
The Way Forward
While Samsung Biologics has yet to comment on the union’s strike vote, the pressure is mounting for the company to engage in meaningful dialogue. The outcome of this situation may set a precedent for labor relations in the biotech and manufacturing sectors.
