So I was thinking about this, and I wondered what the USPS employment statistics looked like. I tried a number of Google searches with no luck. I would note that that in addition to reduced volume, the USPS supposedly does a lot of automated sorting. So if this were any ordinary operation one would think that employment numbers would be down substantially. My guess is that they are higher now than in 2007, and those were higher than years ago when all the sorting was done by hand. But it's just a guess.
