The COVID-19 crisis changed the way many Americans viewed their jobs and how satisfied they were with them. Thus, we saw an increasing amount of Americans flat out leave their job, leave to seek new employment, retire, or at least consider making a major life change change when it came to their careers.
Now, there are a reported 5 million more job openings than unemployed people in the U.S. economy. The sectors with the largest levels of unfilled positions are education, health, and business and professional services, transportation, and utilities. The sector with the highest amount of workers who quit centered in the travel and hospitality sectors. This comes as no surprise seeing how COVID changed these areas for most of the foreseeable future. Many have termed this the "great resignation" as more and more workers leave positions for hopes of career betterment and improvements in their work lives. The Federal Reserve attributes these glaring numbers in employment as factors in the rising rate of inflation. To combat this the FED raised interest rates. Couple these trends with other major macro events and the American and world economy is in a unique place.
