Who would spy on a couple of nonprofit human rights groups?... Who would attack them on the Web for their efforts to improve the lives of workers who pick produce for the world’s largest fast food chains? That’s something the Coalition of Immokalee Workers [CIW] and the Student/Farmworker Alliance would like to know... Burger King spokesman Keva Silversmith says he knows nothing about any Burger King effort to spy on the Immokalee groups... Last month,...the coalition launched a petition campaign. Backed with the threat of a boycott, it aimed to persuade Burger King and others, including the Florida Tomato Growers Exchange, an agriculture cooperative that also opposes the penny-a-pound raise, to pay it and to “eliminate slavery and human rights abuses from Florida’s fields.” That’s when the trouble started... Silversmith denied that [an email claiming that CIW did not help farmworkers] was official BK communication, though he didn’t deny it came from the company. “This is a non-corporate sanctioned opinion. The strident tone does not reflect Burger King, who wants to cooperate and bring real change to Immokalee,” Silversmith says. [also refers to McDonald's, Yum! Brands]
