This research aimed to learn about the flight attendants' work and reflect on actions that prevent and promote these professionals' mental health. To accomplish this, eight professionals from three different airlines were interviewed through individual semi-structured interviews. It was identified that the main tasks of the flight attendants are frequently repeated, such as checking safety and emergency equipment and checking the in-flight service. The positive aspect of the profession most mentioned by the participants is the possibility of getting to know different places and cultures. Among the negative points are the difficulty of being present at moments considered socially important and the physical fatigue. In an attempt to compensate for this tiredness, many flight attendants end up using substances to be able to sleep. The resources offered by companies for mental health care are seen as ineffective. It was concluded that the alternating scales and work routines of the flight attendants affect health conditions and end up generating invisibilities in the mental health care of these professionals. Therefore, it is important to strengthen workers' health actions in this sector given the adversities inherent in the work environment.This research aimed to learn about the flight attendants' work and reflect on actions that prevent and promote these professionals' mental health.

Para isso, foram entrevistados oito profissionais de três empresas aéreas diferentes, através de entrevistas individuais semiestruturadas. Identificou-se que as principais tarefas dos(as) comissários(as) se repetem com frequência, como o check de equipamentos de segurança e emergência e conferência de serviço de bordo. O fator mais citado como positivo pelos participantes é a possibilidade de conhecer diversos lugares e culturas. Já entre os pontos negativos da profissão estão a dificuldade de se fazer presente em eventos familiares considerados socialmente importantes e o cansaço físico. Na tentativa de compensar esse cansaço, muitos(as) comissários(as) acabam usando substâncias para poder dormir. Os recursos oferecidos pelas empresas para o cuidado em saúde mental são vistos como ineficazes, ou pouco efetivos. Conclui-se, que as escalas alternadas e rotinas de trabalho dos(as) comissários (as) afeta as condições de saúde e acaba gerando invisibilidades no cuidado em saúde mental destes profissionais. Logo, é importante fortalecer as ações de saúde do trabalhador neste setor em vista das adversidades inerentes ao meio de trabalho
