Mexican teachers, particularly in the south of the country, have joined a regional rebellion of rank-and-file teachers that erupted in violence in late April. In the state of Guerrero the offices of all three major political parties were vandalized and set afire to protest their support for the educational reform passed by congress and the states over the last five months. At the same time there have been marches and demonstrations in several other states, and there are plans afoot to strike indefinitely beginning on May 1.
