A group of postal workers picketed outside the main branch of the Boise Post Office Thursday.

BOISE -- Postal workers across the country and here in Idaho are picketing today - warning of possible changes they say would cause big problems with the mail.

About a dozen postal workers walked a picket line outside of Boise’s main post office.

The signs read: “Don't let our mail service fall apart.”  The informational picket was organized by the American Postal Workers Union in cities across the nation.  

Members say the U.S. Postal Service is planning to shut down several mail sorting facilities to consolidate operations.

In Idaho, the union says the Twin Falls facility could be closed, with all of the mail sorting now handled there moved to Boise.

"Their mail service is in jeopardy because the Postal Service is looking at doing this behind closed doors. We need to let them know that there is going to be an issue and it could happen," said APWU Idaho President Chris Santos.

"Service is the most important thing to the Postal Service.  It's what people come to us for.  If we don't provide good service they'll go somewhere else, so we won't do these things if we can't do them with maintaining the same amount of service," said Teresa Rudkin, U.S. Postal Service Communication Programs Specialist.

The Postal Service says they are always looking at ways to be more efficient and say the Twin Falls facility is part of a larger study on how to best manage mail service. But they say at this point it is just that, a study, and that no decision has or will be made in the near future.

Rudkin also says that mail is moved overnight and sorted so quickly that customers wouldn't notice any changes in their service, even if letters and packages had to be sorted 100 miles away.
