WASHINGTON (AP) — Negotiators for the U.S. Postal Service and a major postal union are opening talks on a new contract.

The Postal Service’s current contract with the American Postal Workers Union expires on May 20.

Among the issues on the table is whether Saturday deliveries should be pared down in some areas. Congress has refused to allow the Postal Service to eliminate Saturday deliveries.

The union has proposed that the Postal Service be allowed to offer some banking services. Under the proposal, customers would be able to set up accounts where they could get checks cashed and pay bills.

The agency faces deep financial problems because it is required to pre-fund retiree health care benefits.
