The Pasco Processing & Distribution Center has gotten a more than seven-month reprieve from closing.
Moving mail handling from the Court Street building to Spokane has been delayed until February 2013.
The mail handling facility is one of 229 mail processing locations the Postal Service plans to close nationwide as part of an effort to cut costs.
Earlier, Pasco employees were told the Pasco mail handling facility would close on June 30. The post office side of the Court Street building will remain open even when the mail handling portion closes.
Never miss a local story.
"It doesn't necessarily mean that we are saved," said John Michael Wald, president of the local American Postal Workers Union. "It just means that we have bought (several) months."
Last month, the Postal Service announced that the closures would occur in three sets, said Ernie Swanson, Postal Service spokesman.
This summer, 48 of the smallest mail handling facilities will be closing, he said.
Pasco is among 90 that the Postal Service plans to close in early 2013, Swanson said. The rest are expected to close in early 2014. However, the schedule could change.
The closures are supposed to save the agency $1.2 billion each year and mean 13,000 fewer employees nationwide.
The Postal Service is expected to reassess the pending closures, but the study used to determine that Pasco's mail handling should move to Spokane is not expected to be redone, Wald said.
While mail handling may be staying in Pasco longer, not all of the employees are.
Wald said by the end of June, nine workers at the mail handling facility will have left. The mail handling facility had 65 employees.
Those jobs, along with two other vacancies, can only be filled by current Postal Service employees. And other Postal Service workers are looking for jobs at centers that are expected to stay open, he said.
Wald said he thinks the closure decisions will hinge on what Congress does to address the financial burden on the Postal Service, which is self-funded through the sale of postage, products and services.
Congress has not made any reforms to the Postal Service yet, Wald said.
Employees say that the federal mandate for the Postal Service to prefund 75 years of future retirees' health care benefits is the lead cause of the agency's budget woes.
Each year, the agency has borrowed money from the federal government to meet required payments, but recently, it hit its debt limit.
