Abstract

Background
This study analyzed occupational diseases compensated through the government system in the Korean electronics industry and observed changes in the rationale for compensation.
Methods
Data from the Korea Workers’ Compensation and Welfare Service (KWCWS) from 2012 to 2023 were analyzed to examine occupational disease issues in South Korea's semiconductor and display industries.
Results
KWCWS received 174 occupational disease claims between 2012 and 2023, with 88 (51%) approved. The case of a 22-year-old semiconductor worker who died from leukemia has raised awareness and appears to be leading to more claims and higher approval rates. Cancer-related claims, particularly for breast and blood cancers, were the most common. Since 2018, the approval rate for occupational diseases has increased to 60%, which may have been influenced by the Supreme Court's Principle of Presumption of Occupational Diseases and the government’s reduction of the burden of proof. However, approval rates remain lower in small- and medium-sized enterprises (38%) compared to large corporations (56%), likely because of better documentation and unionization in the latter. The semiconductor industry had more claims and approvals than the LCD industry, primarily due to its longer operational history and greater chemical exposure. Conclusions: In South Korea, the increasing approval rate of occupational diseases in the electronics industry from 2012 to 2023 appears to reflect changes in how causal relationships and occupational health policies have been implemented and this is likely due to stakeholder involvement and relevant legal decisions.
