In June 2019, the Taoyuan Flight Attendants' Union initiated a 17-day strike by EVA Air flight attendants, setting a domestic record. EVA Air expressed dissatisfaction over the strike and subsequently filed a civil lawsuit seeking $34 million in damages. However, the Supreme Court upheld the previous rulings and dismissed EVA Air’s appeal on the 25th.

EVA Air claimed significant losses during the strike, including the cancellation of 62 flights, and incurred costs to compensate passengers and travel agencies, including expenses incurred to transfer passengers to other airlines. They sought joint compensation from the flight attendants' union and 12 union officials.

The union argued that they exercised their right to strike through legal processes and that EVA Air could not claim damages due to the provisions of the Labor Dispute Settlement Act. The union emphasized that no violence or illegal acts occurred during the strike, asserting that their actions were within legal rights.
