Charting the Great Resignation The uptick in workers quitting their job during the pandemic, dubbed the “Great Resignation,” isn’t very exceptional, according to [research]( from the San Francisco Federal Reserve bank. When economies recover quickly from an economic downturn, it’s [common for workers to quit]( at about the same rate they have been over the past two years. As job openings increase, workers move around to find better opportunities. [A line graph showing how US employment has changed following recent recessions. Other recessions, including the 2000 tech bubble and the 2007 great financial crisis, saw a steady dip and gain in employment, though the 2007 recessions lasted nearly 80 months. The 2020 pandemic, by contrast, saw a huge dip in unemployment followed by a rapid increase in employment in under 30 months.] The current Great Resignation only feels special because recent economic recoveries have been unusually slow. In the US, it took years for employment numbers to bounce back from the 2000 tech bubble and the 2007 financial crisis; the pandemic recovery, by comparison, has moved at lightning speed, creating the feeling of great turmoil and change in the economy.
