DETROIT, April 21 (Reuters) - United Auto Workers union President Shawn Fain said on Friday there is "no excuse" for Detroit's automakers to set up electric vehicle operations and ventures that are not unionized. Detroit automakers have set up several U.S. joint venture battery factories that are not covered by their current agreements with the UAW. Fain said workers at joint venture battery plants should earn higher wages than production workers at older Detroit Three factories. "I look forward to bring that work under the UAW," Fain said. The UAW president said workers displaced as factories dedicated to combustion vehicle technology lose work should have a right to get jobs at joint venture factories.
