Wal-Mart Strains to Keep Aisles Stocked Fresh

Michelle Obama visited a Wal-Mart in February to extol the fresh, healthy food in the company's grocery aisles. But Wal-Mart, Ms. Obama's corporate partner in a campaign to make food healthier and more affordable, has been running into problems with food that's not so fresh. Wal-Mart, the nation's largest retailer and grocer, has cut so many employees that it no longer has enough workers to stock its shelves properly, according to some employees and industry analysts.
