Yes, Burger King.
From the op-ed:
And now it turns out that the Burger King Corporation, home of the Whopper, hired a private security firm to spy on the Student/Farmworker Alliance, a group of idealistic college students trying to improve the lives of migrants in Florida.
The Student/Farmworker Alliance and an affiliated nonprofit, the Coalition of Immokalee Workers, have for years been urging the fast-food industry to accept some responsibility for the plight of Florida migrants who harvest the tomatoes for its hamburgers and tacos. I am a longtime supporter of their work. The wages of these farm workers, adjusted for inflation, have declined by as much as 70 percent since the late 1970s. And hundreds, perhaps thousands, of migrants have been enslaved by labor contractors and forced to work without pay. The McDonald’s Corporation and Yum Brands (which owns Taco Bell, Pizza Hut and KFC) have agreed to subsidize a modest pay raise for their tomato pickers and work closely with the coalition to eliminate slavery from the fields. Burger King, however, has pursued a different strategy.
