Mario Alberto Castillo and Hector Alvarez Gümez were among 500 members of the National Union of Mine and Metal Workers, known as Los Mineros, who had been on strike for 18 days when 800 police moved in to forcibly remove the strikers. Two men were shot dead and 41 injured, two of them seriously, during the break-up of the strike. No arrests were ever made for the murders.
Dressed in red shirts, some 5,000 Los Mineros members, along with their families, marched to a stone memorial erected in memory of the two men. They were joined by 100 Steelworkers from steel plants throughout District 7 in Indiana and Illinois, a delegation of 10 Unite the Union members from across the United Kingdom and four representatives from Peru representing the mine, metal, steel and energy sectors.
Greeting the mineworkers from his exile in Canada, Los Mineros General Secretary Napoleón Gómez Urrutia noted that although the international community recognizes the legitimacy and leadership of Los Mineros, the Mexican government makes it impossible for him to return to Mexico. Mexico’s labor minister has said publicly that he does not recognize Gómez Urrutia‘s leadership of Los Mineros.
Participants in the memorial also condemned the ongoing repression of the Mexican government against Los Mineros and against all independent unions in Mexico, and called for concrete resolutions to violations of workers’ right to freedom of association in Mexico.
The company, Sicartsa, owned by Grupo Vallacero, was sold to ArcelorMittal after the strike. Los Mineros subsequently negotiated a collective bargaining agreement with ArcelorMittal, which included a 42 percent salary increase.
The April 20, 2006, shooting deaths occurred two months after 65 mineworkers, Los Mineros members, were killed in the Pasta de Conchos mine explosion.
Also speaking at the gathering, Lorraine Clewer, Solidarity Center country program director in Mexico, said that the bullets that had killed Mario Alberto Castillo and Hector Alvarez Gomez did not achieve their aim.
“Los Mineros lives on, stronger than ever, and we are certain that soon the international labor movement will be celebrating Napoleon Gómez Urrutia’s triumphant return to Mexico.
