CHATTANOOGA, Tenn. (AP) Workers will finish casting their ballots Friday in the latest effort by the United Auto Workers union to organize at Volkswagen's lone U.S. plant in Tennessee.

The two-day vote is scheduled to conclude at 8:30 p.m. EST, the end of the work day at the plant.

The election involves 162 skilled trades workers, who are responsible for repairing and maintaining machines and robots at the Chattanooga factory.

After losing a vote among all hourly workers at the plant last year, the skilled-trades workers at UAW Local 42 decided to seek their own election.

Volkswagen objected to the move, but the regional director of the National Labor Relations Board said the group has enough of a shared "community of interest" to allow them to seek their own bargaining unit.
