The United Auto Workers union has filed a new petition seeking to hold a vote on its representation of all hourly workers at Volkswagen's Chattanooga, Tennessee, plant.

The petition was filed Wednesday, the same day the National Labor Relations Board dismissed a previous petition on a technicality.

Volkswagen has said it is neutral on the issue of unionization. But it steadfastly refused to bargain with UAW after the union won representation of maintenance workers at the plant in 2015. VW has argued the bargaining unit needed to include production workers as well.

According to the union, the proposed new bargaining unit would encompass about 1,700 workers at the plant.
