(5)The US Postal Service announced today that it is considering closing about 3,700 post offices over the next year because of falling revenues.
    Facing an $ 8.3 billion budget deficit this year, closing post offices is one of several proposals the Postal Service has put forth recently to cut costs.(6)Last week, for example, Postmaster General Pat Donahoe announced plans to stop mail delivery on Saturdays, a move he says could save $ 3 billion annually. " We are losing revenue as we speak," Donahoe said. "We do not want taxpayer money. We want to be self-sufficient. So like any other business, you have to make choices. "
    Dean Granholm, the vice president for delivery and post office operations, said the first wave of closings would begin this fall.(7)He estimated that about 3,000 postmasters, 500 station managers and between 500 and 1,000 postal clerks could lose their jobs.
