The more than 30,000 California teachers who have gone on strike, supported by numerous students and their parents, demand an increase in the state budget for public schools; the reduction in the number of students per classroom, which currently stands at an average of between 32 and 40.

They also demand that the standardized tests for students and teachers are suppressed and the rescue of the public education system, immersed in a growing process of privatization through the model called charter schools.

The strike affects 600,000 students of the big city, of which 72% are of Latino origin. In those schools it is estimated that students speak 90 different languages, a figure that clearly indicate that the public school is used by an economically disadvantaged population and mostly descendant of emigrants.

The teachers' strike, called and directed by the union UTLA (Union Teachers of Los Angeles), is the first of this magnitude in 30 years, and has been preceded by similar actions in other southern and mid-western states of the US, where the Republican Party governs: West Virginia, Oklahoma, Arizona, Kentucky and North Carolina.

The protests in those States, throughout 2018, ended with the achievement of notable labor and educational improvements, and moved their local political systems. However, the political color of the state and local governments responsible for public education in the US does not seem to affect the tone of the claims of teachers in California, a state led by the Democratic Party (including its capital city, Los Angeles).

It is noteworthy that according to recent figures, 29 states of the US allocate less resources today to public education than 10 years ago. While expanding the privatization system called charter-school, which consists of generous public school funding, by well-known billionaires, in exchange for which they are given the these schools direction and administration in a private matter, through foundations.

A covert privatization program that in the case of Los Angeles affects a fifth of the students of the public education system.

The strike, which has had a huge impact on American public opinion, is also supported by the American Federation of Teachers, the largest trade union in the country, and has the support of the nurse union as well, in what seems like a symptom of the rebirth of the North American trade union movement, which was hardly hit during the time of President Ronald Regan in the 1980s.
