MADISON, Wis. — Republican presidential candidate Scott Walker today will call for sweeping restrictions on organized labor in the U.S., seeking to replicate nationwide his successful effort as Wisconsin’s governor to curb the power of unions.

At a town hall meeting in Las Vegas, Walker will propose eliminating unions for employees of the federal government, making all workplaces right-to-work unless individual states vote otherwise, scrapping the federal agency that oversees unfair labor practices and making it more difficult for unions to organize.

Many of Walker’s proposals are focused on unions for workers at all levels of government, while others would also affect private-sector unions. Labor law experts said such an effort, if successful, would substantially reduce the power of organized labor in America.

While Walker could enact some of the proposals via presidential executive order, others would require an act of Congress or changes in federal regulations. The goal, Walker said, is “to achieve fairness and opportunity for American workers.”

“This will not be easy,” Walker said in a statement to The Associated Press. “Many — including the union bosses and the politicians they puppet — have long benefited from Washington rules that put the needs of special interests before needs of middle-class families.”
