When I went to work at the Downtown Pittsburgh post office on Grant Street in October 1966, postage was five cents.
The usual complaints about discounted "junk mail" no longer apply because advertising circulars are presorted and sequenced by the sender. The postal service must implement "Zip Plus 4 Plus 2" coding to bring about the maximum possible mechanized sorting of first-class mail to replace the manual sorting performed by letter carriers prior to final delivery. The Letter Carriers Union has threatened a strike to prevent that. Jobs will not be saved. Jobs will be lost.
