Staff Photo by Dan Henry / The Chattanooga Times Free Press- 12/4/15. Mike Cantrell, left, president of UAW Local 42, and Ray Curry, director of Region 8, announce the results of an election in which 152 Volkswagen workers voted to join the United Auto Workers union for collective bargaining purposes by 71 percent on Friday, December 4, 2015.

The National Labor Relations Board has certified the results of the United Auto Workers election held at Volkswagen's Chattanooga plant on Dec. 3 and 4.

Maintenance, or skilled trades, workers at the plant agreed to be represented by the UAW for collective bargaining purposes by a margin of 108 to 44.

"We're pleased that the NLRB has certified the overwhelming vote. Our hope is to move forward, sooner rather than later, with collective bargaining for the skilled trades unit," said Mike Cantrell, president of UAW Local 42 in Chattanooga.

VW has said it plans to appeal the NLRB regional director's decision to hold the vote of the maintenance workers earlier this month.
