No Saturday USPS mail delivery could cost 40,000 Post Office jobs and services - Examiner The postal oath, "Neither snow, nor rain, nor heat, nor gloom of night stays these courageous couriers from the swift completion of their appointed rounds" - but the US Congress might. For decades the United States Postal Service had toyed with the idea of a "No Saturday" delivery. With competition from private delivery services like United Parcel Service and Fed-X, as well as so many electronic ways to send messages, the Post Office has been taking a hit for quite some time now. You can even send greeting cards via the computer. There is no indication how many Atlanta jobs will be affected but it is expected to be 40,000 nationwide. The changes and loss of so many jobs will have a trickle down affect with those who do business with the post office, even the contract drivers and air service employees. There will be many families who will be adversely affected by such a change - bringing the total affected to over 100,000 or more.
