As South Korea prepares to implement the Yellow Envelope Law, a discussion was held in Ulsan focused on improving the labor rights of subcontracted workers in the shipbuilding industry. The event, organized by the Ulsan Dong-gu Support Center for Irregular Workers, convened policymakers, academics, and labor activists to examine the implications of the law, which aims to enhance the responsibility of primary contractors towards their subcontracted employees. The significance of this law is pronounced, especially given that subcontracted workers often face greater challenges in negotiating their rights and are frequently marginalized within the corporate structure. The discussion highlighted how the law might reshape the negotiation landscape between primary and subcontracted workers and potentially assist them in advocating for better working conditions and labor rights. Experts emphasized that the implementation of the law could encourage more active participation from subcontracted workers in labor movements. Furthermore, the Ulsan Dong-gu Support Center plans to support educational initiatives aimed at expanding labor rights for approximately 20,000 subcontracted workers at Hyundai Heavy Industries. This educational effort underscores the importance of equipping workers with the knowledge and skills necessary to navigate the changing labor landscape and advocate for their rights more effectively in light of upcoming legal changes.
