California officials face mounting criticism from union leaders over plans to let retail giant Wal-Mart Stores Inc .enroll shoppers in President Obama’s healthcare expansion. The state wants retail workers to help consumers enroll in healthcare expansion. Critics say Wal-Mart does not provide adequate health coverage and shouldn’t be advising consumers on the matter. The state wants employees at Wal-Mart and other retailers to help consumers learn about their options and assist them in buying federally subsidized private insurance. These plans are part of state efforts to implement the federal healthcare law and reach out to 5 million Californians eligible for new coverage starting in January according to a report in the Los Angeles Times.
