The first salvo in the campaign included an open letter to Californians, placed in paid ads in 15 major newspapers throughout the state. Spokesman Eric Berger says the world’s largest retailer decided to take its message directly to residents because of what the company calls “misinformation” spread by organized opponents.  BERGER :10—We are tired of the misinformation out there and we’re going to do everything that we can to set the record straight about Wal-Mart and its impact on California communities.   Berger says anti-Wal-Mart forces are responsible for allegations that the company mistreats its employees. Wal-Mart is facing organized opposition in a number of cities including Turlock, Stockton and Lodi. Detractors contend Wal-Mart pays low wages, and causes traffic congestion in areas where it builds so-called SuperCenters. Bob Hensley KXJZ News.
