CEVA Logistics U.S. Inc. plans to permanently lay off nearly all of its workers at its warehouse operations in Plainfield, resulting in the loss of more than 250 jobs.

According to a notice sent this week to the town of Plainfield, the layoffs will take place in stages between May 10 and June 30 at the distribution facility at 800 Perry Road in Airwest Business Park.

CEVA, a third-party logistics company based in the Netherlands, said in the notice that the cuts were “due to a decision by our customer to reorganize its parts distribution system.”

John Deere & Co. is believed to be CEVA’s only customer at the warehouse.

The company did not say if the operations were completely closing down, but did say the layoffs affected "substantially all of its workforce" at the facility.

Jeff DeLoughery, general manager at the distribution facility, declined to comment on the decision Wednesday morning. He referred questions to CEVA’s corporate headquarters.

A spokesperson for CEVA declined to comment, but issued the following statement: "CEVA can confirm that its operation in Plainfield, Ind., will be permanently downsized over the next four months time. We informed our employees at the site on March 8, 2010, and our priority is to keep them up to date with any future developments."

More than 200 of the workers are represented by Local Teamsters Union No. 135. The rest include administrators, management and security personnel.

Plainfield Town Manager Rich Carlucci said he didn’t know the reasons behind the layoffs. He said the situation is disappointing for Plainfield, but the blow has been softened somewhat by other recent jobs announcements.

On Monday, startup logistics firm s2f worldwide LLC said it would invest $10.8 million to set up its headquarters and distribution center in Plainfield, creating 250 jobs by 2013.
