On April 28 Mexico's Federal Conciliation and Arbitration Board (JFCA) ruled in favor of a nine-month old strike at Grupo Mexico's giant copper mine at Cananea, in the northwestern state of Sonora. The ruling, which is final, makes the job action legal. Previously the JFCA had ruled against the strike—which was started by the National Union of Mine and Metal Workers of the Mexican Republic (SNTMMRM) over safety issues on July 30—and the government sent troops to the mine in January. Grupo Mexico must now end the partial operations it was carrying out at the mine. (La Jornada, April 29) On April 24 the company had threatened to close the facility, as it is reportedly doing in the San Martin mine in Zacatecas. (Mexican Labor News and Analysis, April 2008)
