Abstract
The coronavirus disease (COVID-19) outbreak has impacted the restaurant industry tremendously. Building on the Conservation of Resources Theory, the current study investigates the relationships among U.S. restaurant frontline employees' fear of COVID-19, job insecurity, and emotional exhaustion. The study also examines the moderating role of employee mindfulness and perceived organizational support. SPSS PROCESS macro was used for hypotheses testing. Results suggested that restaurant frontline employees' fear of COVID-19 was positively associated with both job insecurity and emotional exhaustion. Fear of COVID-19 had an indirect effect on restaurant frontline employees' emotional exhaustion via job insecurity. Employee mindfulness buffered the positive relationship between fear of COVID-19 and job insecurity. Perceived organizational support was found to intensify the positive relationship between job insecurity and frontline employees' emotional exhaustion. The research provided useful human resource management practices for U.S. restaurant businesses amid crises such as COVID-19.
