"According to the EPMU, since 2008 nearly 40,000 manufacturing jobs have been lost to the economy."
I checked the 2012 HLFS data here against the 2008 HLFS data here
June 2008 186,300 manufacturing jobs
June 2012 175,100 manufacturing jobs
BUT there were 184,600 in March 2012. Obviously a good deal of fluctuation occurs. Nevertheless the lost jobs as quoted by EPMU will have been counter-balanced by created jobs.
