Today's initiative came from the National Union of Education Professionals (Sinape), which has warned of "a devaluation of salaries for these education professionals" since 2010.

In the strike notice, Sinape states that these professionals "saw their salaries 'swallowed' by the national minimum wage, without there being a restructuring of their careers".

The strike takes place three days after the strike by teachers and educators called by the platform of nine union organizations, of which Sinape is a member, as well as the National Education Federation (FNE) and the National Teachers' Federation (Fenprof).

According to a report carried out by the platform in the early afternoon of Friday, the strike had a participation rate of over 80% and "around 90% of schools" were without classes.

Today's strike is the third of the current school year, which began less than a month ago and in the first few days included a week-long strike called by the Union of All Education Professionals (STOP) and aimed at teachers and non-teaching staff.
