President Dennis Williams of the United Auto Workers (UAW) rejected a third tier of lower wages for members who work in the automobile industry. On Wednesday, Williams spoke at the union's national bargaining convention in Detroit which sets the agenda for the union's bargaining efforts with the auto companies and other industries. He said that the UAW already has too many tiers of lower wages.

Williams was responding to reports that General Motors Co. and Ford Motor Co. may propose a third tier of pay. He already is under pressure from union members to end a second tier of wages that's about half the $28 per hour made by longtime workers.

He was responding to reports that General Motors Co. and Ford Motor Co. might propose a third tier of pay. Williams is under pressure from union members to end a second level of wages that starts around $15 per hour, about half the $28 per hour made by longtime workers.

At the convention, he told the delegates about bridging the gap in wages. Fiat Chrysler, GM, Ford and the UAW will begin contract talks this summer. The union represents about 137,000 workers at the three companies. The current contract will expire in September.
