Drivers working out of FedEx Freight’s Cinnaminson, New Jersey, facility have rejected an organizing attempt by the Teamsters Union.

While the union has not issued a public response to the vote, FedEx released a statement applauding the decision.

“FedEx Freight respects each employee’s right to make his or her own decision, but we prefer to work directly with employees without involving a union,” the company said. “We believe our drivers in Cinnaminson made the right decision, and we are proud of their ongoing commitment to providing the highest standards of service to our customers.”

The vote is the latest setback for the union in its attempts to organize workers at the package and trucking giant. Currently, the only FedEx workers in the U.S. who are union members are pilots. About 14 workers at a FedEx facility in western Canada recently signed cards saying they want to be represented by the Teamsters.

The Teamsters last month filed a petition with the National Labor Relations Board seeking an organizing election at the FedEx Freight terminal in Harrisburg, Pennsylvania, that was approved, but a date for an election has not been set.
