Synthesizing the conservation of resource theory, proximal withdrawal state theory, and job demands-resources theory, the present study examined the relationships between two dimensions of emotional labor (i.e., surface and deep acting) and turnover intention, as well as the moderating role of perceived organizational support in these relationships, such as the context of Korean firefighters. Using survey data drawn from fire organizations in Gyeonggi-do, the largest province of South Korea, we found that both surface and deep acting are positively related to firefighter turnover intentions. Further analysis indicates that the perceived organizational support of firefighters, vital for public health and safety, attenuates the positive relationship between surface acting and turnover intention but has no significant moderating effect on the relationship between deep acting and turnover intention. Our results suggest that perceived organizational support acts through essential psychological resources to recover the loss of emotional resources and contributes to the retention of firefighter personnel who primarily perform challenging and stressful work, including firefighting and offering emergency medical services. Thus, this study examines a crucial tool to ensure firefighters' public mental health.
