I truly do -- and did -- understand the difference between 1966 and 1969. The fact remains that the Post Office employed some 960,000 in 1969.
My point was that the Post Office has severly reduced its workforce.
Yes, the workforce is down ~ i had something to do with that. put me in charge of USPS for 2 years ~ on a special consulting contract ~ they don't pay enough for me to show up otherwise ~ and i'd top off a 1000% productivity improvement while speeding up average origin to destination times.
