Seventy thousand teachers in the Mexican state of Oaxaca struck May 23, demanding better funding for their students. The strike began with a march from four different points to the city’s square, where the educators rallied and then spread out to put pressure on both government and business.
Teachers blockaded government offices and private companies, closed major intersections, and “liberated” the toll booths on the privately owned highway to Mexico City. They also attempted to shut down the airport.
