A group of tomato pickers from Florida have claimed victory in a four-year campaign against Taco Bell. The Coalition of Immokalee Workers called off a national boycott of Taco Bell Tuesday after restaurant officials agreed to improve wages and working conditions for tomato pickers. The Coalition of Immokalee Workers is made up largely of indigent immigrants who work tomato fields in southwest Florida. Also as part of the agreement Taco Bell’s parent company Yum Food announced it will help to ensure that none of its tomato suppliers employ indentured servants. In recent years the Coalition helped federal authorities prosecute farm bosses in Florida for holding workers as slaves. The four-year boycott has grown in recent years largely due to support from college students. 21 colleges had successfully removed or blocked Taco Bell from operating on their campuses.
