The members of the Twin Falls City Council heard from local postal workers last night regarding a plan to consolidate mail processing centers in Twin Falls and Boise. It's a move some postal workers said would result in jobs lost and slower deliveries. All mail from zip codes beginning with 833 in eight counties would be processed in Boise.  Only mail that machines can't sort would still be processed in Twin Falls.  It's a move the Postal Service says would save money, but Twin Falls Postmaster Bill Reese disagrees.  Reese said there would likely be a net decrease of six jobs in Twin Falls.  He said some jobs would be created in Boise. The plan could also include moving some employees in Twin Falls to Boise, but details are still being worked out. The American Postal Workers Union Local 179 in Twin Falls says their information indicates about 20 to 30 jobs would be lost.  They said a consolidation would delay deliveries and pick-ups. The Postal Service says they don't anticipate any delays.  After hearing from union representatives the City Council voted unanimously to support the mail processing center.
