More than 50 tomato pickers have ended a six-day fast outside the headquarters of Publix Super Markets in Florida. The Coalition of Immokalee Workers organized the “Fast for Fair Food” campaign in an effort to win better working conditions and pay for the thousands of workers who pick the tomatoes sold in the grocery store. On Saturday, Ethel Kennedy, the widow of the late Robert F. Kennedy, and their daughter, Kerry Kennedy, broke bread with the workers as they ended their fast.
