Yet the total "aggregate weekly hours of production or nonsupervisory workers" is still below the 2002 level: http://stats.bls.gov/news.release/empsit.t18.htm
The St. Louis Federal Reserve graphically tracks this number pretty well. You can see it at the link below, which shows that the real trough in total labor demand was in 2003: http://research.stlouisfed.org/fred2/series/AWHI/11/10yrs
Work seems to be being spread around a bit more, but the total labor needed still seems to have increased only modestly, and nowhere near older levels.
