A bill sponsored by Sen. Ton Carper, D-Del., chairman of the subcommittee that oversees the Postal Service, calls on the USPS to "develop a plan for the expansion of retail alternatives to post offices, such as self-service kiosks, vending machines, the Internet, Postal Service employees or contractors on delivery routes, and contract postal units."
That bill has been referred to the Committee on Homeland Security and Governmental Affairs.
In a July statement, Carper said, "The Postal Service is facing a dire fiscal crisis and two challenges -- the rapid transition to electronic communications and the lingering after effects of the Great Recession -- which threaten its very existence. In order to survive, let alone thrive in the 21st century, all options have to be considered and the Postal Service has to modernize the way it does business, including where and when it does business."
