From today's AP article "Wal-Mart to Air Reputation Ads:"

Wal-Mart Stores Inc. will run national television ads starting Monday praising its record as an employer and corporate citizen, taking its arguments straight to the public in an ongoing battle over its reputation with unions and other critics.

The world's largest retailer, increasingly a lightning rod for politicians as well as labor unions and other activists, cites the legacy of late founder Sam Walton in a folksy 60-second ad. A 30-second ad focuses on Wal-Mart's health insurance plans for its more than 1.3 million U.S. employees...

Union-funded campaign groups have also recruited national Democratic figures to back their calls for higher wages and better health care at Wal-Mart, including potential 2008 presidential contender Sen. Barack Obama of Illinois and declared 2008 candidate John Edwards.

WakeUpWalMart.com, a union-funded campaign group, said the ad campaign proves Wal-Mart is seeing damage to its bottom line from a worsening reputation. The retailer had its worst holiday sales season in years, WakeUpWalMart.com spokesman Chris Kofinis said.

"Wal-Mart is living in a bizarre state of denial, where no matter how bad their public reputation is, they still believe that a tired ad campaign can fool the American public into believing it is OK to exploit millions of working families," Kofinis said.

WakeUpWalMart.com and another union-backed group, Wal-Mart Watch, claim Wal-Mart pays poverty wages, runs small businesses out of town and pushes employees onto tax-funded public health care. Wal-Mart denies those allegations.
