Federal police in Mexico have forcibly removed strikers from a copper mine at the heart of a long-running labor dispute. Workers have occupied the Cananea copper mine for the past 3 years, calling for better on-the-job safety guarantees. The Cananea mine is Mexico’s largest source of copper. The company that owns the mine, Grupo Mexico, says it will renew operations with 2000 contract workers. The national miners’ union has announced it will shut down one of Mexico’s busiest ports and carry out a series of actions throughout the country.
