In 2019, workers were quitting their jobs at record rates, with labor experts saying workers did so in order to secure the pay raises and promotions they weren't getting from within.

Then, beginning in March 2020, the labor market shed 20.5 million jobs in the first few weeks of the coronavirus pandemic. Now, a year later, there are still nearly 7.9 million fewer Americans counted as employed than in February 2020, while the labor force is down 3.9 million.
