Former slaves Jose Fabio Lucas de Lima (L) and Adauto Iz'dio Ferreira work at the construction site of the Arena Pantanal stadium in Cuiaba, Mato Grosso state February 7, 2012. A total of 25 men are working at the site of one of Brazil's new World Cup soccer stadiums, who, in their previous jobs, worked in conditions that were classified as slave labor by the Brazilian government. They are now helping to build the stadium in the western city of Cuiaba as part of a state-sponsored program that trains former "slaves" in skills like carpentry and helps insert them into the regular workforce.
