The COVID-19 pandemic has exposed the vulnerability of frontline employee (FLEs) to infections and other hazards and highlighted the importance of workplace safety practices (WSP) for service organizations. In response to the critical issue of service safety, we developed and empirically tested a model proposing that WSPs negatively influence FLE perceptions of pandemic related threats and positively influence their perceptions of organizational supportiveness (POS). In turn, these perceptions have time-lagged effects on two aspects of FLE wellbeing—reduced emotional exhaustion and increased work engagement. Utilizing data from a two-wave (separated by a month) survey panel consisting of 310 FLEs across the United States, we found evidence for all hypothesized relationships. We discuss the practical and theoretical implications of our findings and provide suggestions for future research on service safety on the organizational frontlines.
