ANN ARBOR - In an election conducted today by the National Labor Relations Board at Con-way Freight’s Portland, OR maintenance facility, employees voted to reject representation by the International Brotherhood of Teamsters. Joseph M. Dagnese, president of Con-way Freight, commended Portland employees for their diligence in examining the issues, and ultimately expressing their confidence in the company.  “I want to thank our employees for the thorough and careful consideration they gave to this matter and for voting to remain union-free,” said Dagnese. “We continue to believe that our best path forward is one where we are focused on our customers, working together directly with our employees to deliver a superior service experience, without the interference of a third party.”   Con-way Freight currently does not have a contract with a union at any of its nearly 300 locations in the U.S.
