I would guess what Zero Hedge is talking about is the very real phenomenon where people dropping out of Unemployment programs are no longer counted as employed. They are "discouraged workers" and only get counted in U6 Unemployment figures.
So if you have 3 out of 10 people unemployed but enrolled in a jobs program then U3 would show 7/10 employed and a 30% unemployment. If those 1 of those people drops out of the unemployment program, even though they never found a job, the U3 number is 7/9 or 23% unemployment. It looks like unemployment is dropping when in fact it isn't.
What we will see, more than likely, is a precipitous drop in the U3 unemployment with a far smaller or non-existent drop in U6 unemployment.
