In the United States, the Bureau of Labor Statistics (BLS) is reporting that more workers quit their jobs in December 2015 than at any other point in time since December 2006.

The monthly report on job opening and labor turnover showed that over three million people gravitated toward the exit sign while employers took on over five million workers. These numbers account for some of the highest reported since the 2007-2009 recession began.

Human resource experts fear that the market has become too much of a candidate’s market, spurring more voluntary separations from employers. Candidates know that they’re able to demand more pay with more benefits and employees are more confident now than ever before.

Unemployment rate in the United States is at an all-time low of 4.9 percent, which is within the range considered to be full employment. With this increase in the quit rate, human resource professionals will really have to amp up their retention program to keep valuable talent. Unfortunately, wage increases are probably at the top of these retention programs, as employees are well aware of their worth.
