The financially struggling U.S. Postal Service sought Wednesday to tamp down concern over wide-scale cuts, revealing it will seek to keep thousands of rural post offices open with shorter hours.

At a news briefing, Postmaster General Patrick Donahoe said the mail agency was backing off its plan to close up to 3,700 low-revenue post offices sometime after May 15. Citing strong community opposition, Donahoe said the agency will now whittle down full-time staff but maintain a part-time post office presence in rural areas, with access to retail lobbies and post office boxes.

Under the emerging strategy, no post office would be closed. But more than 13,000 rural mail facilities could see reduced operations of between two and six hours.
