Wal-Mart Stores Inc., the world's largest retailer, has been trying to rekindle growth in its U. S. operations. Sales at its U. S. stores have been declining due to remodeling projects, limited opportunities for growth, and problems with its clothes offerings. In addition, the low-income shoppers who patronize Wal-Mart have less money to spend because of higher gas prices. Wal-Mart has been very candid about its need to implement a growth strategy for its U. S. stores. In 2007, Wal-Mart named Bill Simon chief operating officer and Pat Curran executive vice president of people as it redesigned its organizational structure and shifted its executives to different posts. According to Wal-Mart, Simon will oversee five operation's presidents, representing 3,400 stores, and will also manage the companys pharmacies, optical businesses, and in-store medical clinics. Curran will lead the companys new human resources division, which will oversee Wal-Marts nearly 1.2 million U. S. employees. In 2006, Wal-Mart tried to enhance its image by playing down its discount roots. It stocked upscale items like organic food and plasma TVs, hoping wealthier consumers would spend more at its stores. But its lower-income customers balked at some of the changes, and Wal-Marts profits suffered. Refer to Wal-Mart.
