Guatemalan teachers have held several strikes this year against attempts by President Oscar Berger to privatise Guatemala's 17,400 state schools.
The teachers also demanded better wages, nutritional meals for school children and increased funding. They ended their most recent three-week strike and road blockade in mid-May when the government pledged to meet their demands.
Joviel Acevedo, president of the National Teaching Association in Guatemala, is a leading figure in the struggle. He describes the Berger government as representing the traditional oligarchy that is responsible for Guatemala's poverty and wants to sell state schooling down the drain.
