Hours will be slashed in half at the Marshall Post Office in January 2015 as part of a nationwide downsizing, U.S. Postal Service employees told a frustrated crowd on Tuesday. The reduced hours are “self-defeating” since limiting retail service will drive revenue even further into the ground, locals said. Some said their business will be hurt without an afternoon pickup. Postmaster Chris Knowles, who’s manned the branch since 2005, says the cut in hours may force him to transfer elsewhere. “I hope we aren’t dismantling the best post office system in the world,” one woman said.
