The leading organized labor group representing auto industry laborers has not voiced complaints toward the Obama administration on its decision on General Motors and Chrysler, one of the administration's leading economic advisers said Monday.

Asked if the United Autoworkers (UAW) union had voiced their displeasure toward the plan, Jared Bernstein, Vice President Biden's senior economic adviser, said: "Not hearing it, no."

"I would argue that the UAW has really made considerable and deep concessions over the course of these deliberations," Bernstein said.

Bernstein also said that the administration was extremely unlikely to revisit the fuel efficiency standards expected to be put in place in exchange for additional government assistance.

"I don't think there's any reason to go there, in terms of conceding territory," Bernstein said. "I don't think it helps anybody to inject new criteria at this point."
