2019年12月下旬，新型冠狀病毒（COVID-19）隨著國際間跨境遷徙人口的快速流動，迅速擴大蔓延至全球，引發一場近兩年之全球隔離行動。以邊境防疫政策為主軸的臺灣政策與社會象徵秩序為背景，國際航空公司的營運模式與頻繁跨越國家邊境且接觸全球各國移動人流的跨國勞動者—航空業機組人員皆受到了極大的衝擊。本研究藉由深度訪談、參與觀察和對國家政策、新聞媒體的實物分析，探討針對航空業機組人員所制定之「國籍航空機組員健康防疫管控措施」於臺灣邊境防疫政策中所帶來的效益，以及對航空業機組人員之影響。研究結果顯示，該政令為同時扮演了外來者、歸國者、移民接觸者等多重角色的機組員在勞動環境、勞動條件、生活能動性方面帶來諸多負面效應。甚且透過權力的運作與媒體的傳播形塑該特殊職業群體的污名標籤，造成社會排斥的現象。深入研究發現，隨著疫情的擴展而相應出的規範網絡，使多數機組員逐漸內化危險他者的意識並自我監控，同時也陷入雙重忠誠的困囿中。由外而內的種種枷鎖，使機組員在職業與個人的身分認同和社會互動上更顯窒礙難行。

In late December 2019, the coronavirus (Covid-19), originating from Wuhan, China, swiftly spread globally due to the rapid movement of international cross-border populations. This triggered a nearly two-year-long global quarantine initiative. Against the backdrop of Taiwan's policy and societal symbolic order centered around border control, the operational model of international airlines and the transnational labor force of aviation industry crew members—constantly crossing national borders and interacting with mobile populations from various countries—have faced significant challenges. This study, employing in-depth interviews, participant observation, and analysis of given national policies and news media content, explores the effects of the " Crew Health Control Measures for Epidemic Prevention " implemented for aviation industry crew members within Taiwan's border epidemic control policy. The research findings reveal that these transformations on regulations has adversely impacted crew members, who simultaneously play multiple roles as foreigners, returnees, and immigrant contacts, in terms of the working environment, labor conditions, and life autonomy. The operation of power and media communication has constructed a stigma for this unique professional group, leading to societal exclusion and exacerbating difficulties for crew members in terms of occupational identity and social interaction.
