The U.S. Postal Service is expected to announce that it will discontinue letter services on Saturdays. The agency says the move will save about $2 billion a year. The move comes as the Postal Service seeks ways to cut costs, due to deficits relating to a law that requires them to pay money into a future retiree health fund. The American Postal Workers Union, which represents about 220,000 workers and former employees, said that the move will only hurt the postal service.
