The Platform in Defense of Public Education, made up of the Confederation of Parents and Students Union, supported the strike, which was the first in the history of Spanish democracy to be made jointly by all levels of education.

At a press conference, representatives of labor unions FETE-UGT, FE-CCOO., ANPE, CSIF and STES asked the parents of 7.5 million students to not take them to school that day.

They also proposed to the entire school community a night vigil in schools from May 21 to 22, and schools to hand green banners during the strike in all provinces.

The Congress of Deputies passed Thursday the cuts of 10 billion euros in education and health that was approved on April 20 by the Executive.
