The South Korean government's consideration of integrating the Incheon International Airport Corporation with Korea Airports Corporation and Gadukdo New Airport Construction Corporation has sparked significant opposition, particularly from labor unions. The Incheon Airport Joint Committee for Preventing Sudden Integration, made up of labor groups, firmly stated their dissent, arguing that the unity of these companies would not enhance efficiency and that it endangers the competitive edge and public service their workers have maintained. They strongly oppose the notion that the integration will benefit Incheon Airport, asserting that it would merely shift financial responsibilities onto them while the government tries to manage its own failures in airport policies.

The proposal to merge these three institutions arises amid concerns about the operational efficiency of Gadukdo New Airport, with suggestions that Incheon Airport may need to cover part of the construction costs. Proponents argue that having distinct institutions run various airports might lead to inefficiencies, providing a rationale for integration. However, the labor union refutes this, claiming such moves are merely attempts to absolve the government of the failures associated with local airport policies and the burgeoning financial burdens of new airports. Their statements highlight the ongoing lack of viability and demand for local airports, which cannot be resolved overnight.

Moreover, dissenting sentiments are echoed within the internal communications of the Incheon International Airport Corporation. Employees are openly expressing their grievances, with some suggesting that action, such as strikes, may be necessary to resist the integration. There is a growing concern that the government's approach to addressing the financial strains associated with local airports is misplaced and unfairly targets the workers at Incheon Airport, thereby leading to a potential crisis in the aviation sector if their calls for accountability are ignored.
