Truck drivers at LTL carrier Con-way Freight’s Bakersfield, California, terminal on Thursday voted to reject representation by the Teamsters Union.

The decision marks the fifth election defeat for the Teamsters, who have been attempting to organize employees at various Con-way Freight facilities for the past five months. The company announced the results, though vote totals were not disclosed.

Last year, the Teamsters won union organizing elections at three Con-way Freight terminals, including its first ever at the company, with victories in Laredo, Texas; Vernon, California, and Miami Lakes, Florida.

However, other facilities turned down the union. The Bakersfield vote follows previous Teamster defeats in elections at Con-way Freight facilities in Santa Fe Springs and San Fernando Valley, California; Manchester, New Hampshire, and Harlingen, Texas. Earlier, the Teamsters withdrew a petition for a vote at Con-way Freight's facility in Irvine, California.

"We are gratified by the support and confidence of our Bakersfield employees, as well as the support of all the employees at our other facilities who have rejected the Teamsters' advances," said Greg Lehmkuhl, president of Con-way Freight. "We remain convinced that our path to success lies in maintaining an open, respectful and direct relationship with our employees without the interference of a third party."

Con-way Freight currently does not have a contract with the Teamsters Union at any of its nearly 300 locations in the U.S. despite the union winning three organizing elections.
