The Hattiesburg Post Office's Customer Service Mail Processing Center will be moving to Mobile, Alabama, in 2015.
Enola Rice, U.S. Postal Service spokeswoman, tells The Hattiesburg American Hattiesburg, Grenada and Gulfport mail processing will be part of Planned Phase 2 of consolidating up to 82 facilities beginning in January.
Rice said the consolidations will be completed by the fall mailing season.
The consolidation was not welcomed news for some employees at the Hattiesburg facility.
Timothy Eaton says he doesn't think any employees will lose their jobs.
Eaton says postal employees are unionized and can't be laid off.
In 2012 and 2013, Rice says the postal service consolidated 141 mail-processing facilities but no employees lost their jobs, and the move saved approximately $865 million.
