A church-backed group of farmworkers and supporters have joined a 30 November 2007 nine-mile march through Miami to the headquarters of Burger King to demand higher wages and better conditions in Florida's tomato fields.

The Rev Clifton Kirkpatrick, who moderates the General Assembly of the Presbyterian Church (USA), is urging fast-food giant Burger King to work with the Coalition of Immokalee Workers (CIW) to address wages and working conditions in the tomato fields.
