COVID-19 has made service sector jobs much more dangerous. But, while the Centers for Disease Control and Prevention (CDC) released guidelines to prevent infections in the workplace, employers were largely left to adopt measures at their own discretion. Scattered reports suggested that these efforts often fell short, especially early in the pandemic and that substantial variation in the adoption of safety practices persisted across states and firms.
