The Labor Department says that productivity grew at 3.1% between July and September. The increase is the largest in a year and half. The growth means that employers had to pay less for more work, which is good for employers but not for job growth. While rising demand and lower productivity often means job growth, economists worry that the demand seen during the summer will not be sustained.
