Unionized workers of Asiana Airlines reaffirmed their opposition to the proposed merger with Korean Air, stating their determination to use all available means to impede further progress. The labor unions called upon Asiana Airlines' main creditor, Korea Development Bank, and the European Commission to thoroughly reassess the merger, which has received conditional approval from the EU's antitrust regulator. Possible courses of action outlined by the general labor union and pilots' labor union include the resignation of cargo flight attendants and allegations of breach of trust against Asiana Airlines CEO Won Yoo-seok. Despite numerous attempts to engage in dialogue with Korean Air's management regarding job security and fair treatment of employees, the unions claimed to have received no satisfactory responses. The head of the pilots' union, Choi Do-sung, emphasized during a press conference in Seoul that the recent selection of Air Incheon as the preferred bidder for Asiana Airlines' cargo business, which he described as "a small cargo airline with no long-distance flight experience," was seen as a move by Korean Air to seize control of the cargo sector. Furthermore, the general union head, Kwon Soo-jeong, argued that the merger would significantly harm the competitiveness of the nation's infrastructure industry, as the creation of a 'mega-carrier' as proclaimed by Korean Air was compromised by the relinquishment of numerous slots and the sale of the cargo business. The absence of Craig Malcolm, chairman of the Associations of Star Alliance Pilots, who was invited to the conference, was attributed to the difficulty faced by airlines affiliated with Star Alliance in fully supporting the union due to their interest in obtaining the slots that might become available in the event of the merger.
