United States and South Korea have different labor relations practices and systems. The U.S. tends to emphasize individual employment contracts, decentralized bargaining, and a more employer-centric approach, while South Korea has a history of strong collective bargaining, worker activism, and a focus on job security and social welfare. Collective bargaining is common and typically occurs at the industry level in South Korea. Industry-wide labor agreements set wage and working condition standards across sectors, with negotiations between labor unions and employer associations. However, unionization rates in the U.S. have declined over the years. Labor unions negotiate contracts at the enterprise level, leading to a decentralized collective bargaining system. South Korea has faced concerns regarding long working hours and a demanding work culture, although there have been efforts to address this issue in recent years. In the U.S., there is less pressure regarding working longer than regular hours, and also provide overtime pay for any hours worked over.
