Well, my ignance, such as it is, come from lifetime of observation backed up by Googling. You always seem to show up to defend the bloated Post Office whenever these threads arise. I thought there was all sorts of automation, and less mail these days. (To say nothing of reduced counter hour and box mail hours at the POs I go to.) No GS15s are sorting the mail, delivering it or mopping the floors around here.
