In the present study, we seek to understand how public sector employees that go to work to perform essential duties for the society and the economy cope with the fear of COVID-19 and maintain their motivation, energy, and enthusiasm for their work. We hypothesized that because employees are motivated to protect their health, an increase in daily fear of COVID-19 would be related to a daily increase in coping behaviors in the form of job crafting, which would consequently be related to employees’ daily motivation. Data were based on 64 tenured employees working in public service organizations during the third wave of the COVID-19 pandemic (March 2021), who completed a quantitative diary for five consecutive workdays (N = 320 occasions). Results from multilevel analysis indicated that fear of COVID-19 had an indirect effect on work engagement through only one dimension of job crafting, seeking job resources. The study contributes to the ongoing theoretical extension of the beneficial role of job crafting by suggesting seeking social resources as an effective coping strategy for fear of COVID-19.
