"Job openings fall for second straight month"

OK, people leaving the labor force and job openings dropping.

Employers posted fewer job openings in December, the second straight month of declines. That's a sign hiring is still weak even as the economy is gaining strength.
The Labor Department said Tuesday that employers advertised nearly 3.1 million jobs that month, a drop of almost 140,000 from November. That's the lowest total since September.
Openings have risen by more than 700,000 since they bottomed out in July 2009, one month after the recession ended. That's an increase of 31 percent.
But they are still far below the 4.4 million available jobs that were advertised in December 2007, when the recession began. . . .
