This chart is all over and there is little new to say about it.
However, you may notice that the curves of these employment recessions tend to be symmetrical, meaning it takes about as long to recover as it did to reach the nadir.
We are 26 months into this employment recession (it started, remember, in December 2007) and the curve is flattening out, hopefully meaning we are nearing the bottom. But that still means we are more than two years away from full recovery. With luck, things might start looking rosy around the summer of 2012.
