**5. Conclusions**

This study shows that the di fferences in job engagemen<sup>t</sup> and job retention intention of nurses working on the frontlines of the COVID-19 situation depend on their social characteristics and support. Di fferences in job engagemen<sup>t</sup> and job retention intention are based on nurses' individual characteristics and working environments, so these characteristics must be considered in operations for nurses to continue in their jobs. In particular, the job retention intention of nurses working in COVID-19-related divisions was low; this issue should be taken into careful consideration. Low job retention intention could cause significant damage to the nursing workforce, and it should be recognized that this may cause hardships in overcoming the COVID-19 pandemic. To win against COVID-19 and adequately prepare for a future COVID-19 pandemic situation, press media targeting nurses (e.g., news, articles, and documentaries) should become more active and family support should be provided.
