Workers at a FedEx Freight terminal in Charlotte, North Carolina, voted to be represented by the Teamsters union, while Teamsters withdrew a petition for an election at FedEx Freight’s terminal in South Newark, New Jersey.

“The union would only take this step if it anticipated losing the election,” FedEx Freight said of the New Jersey vote withdrawal.

FedEx Freight said it may appeal the Nov. 19 Charlotte vote. The Teamsters said that vote affects 222 drivers at the terminal. Neither the company nor the union disclosed the vote tally.

“No other drivers at our more than 360 service centers are impacted by this vote,” FedEx Freight said in a statement. “It remains business as usual at FedEx Freight. and our nationwide network won’t miss a beat.”

Over the past two months of stepped-up Teamsters organizing activity, Con-way and FedEx have won some contests, and the union has prevailed in other representation votes.

FedEx Freight is part of FedEx Corp., which ranks No. 2 on the Transport Topics Top 100 list of U.S. and Canadian for-hire carriers.
