This decision comes after the collective ratified in a consultation their willingness to escalate the conflict with the administration. The protest model will combine territorial stoppages with unitary strikes across the country, similar to what was carried out last March.

The four convening union groups –USTEC, Professors de Secundària, CGT, and Intersindical– have set a total of 17 days of stoppages. The mobilizations will begin with a sectoral strike in nurseries and a unitary teachers' strike on Tuesday, May 12. This will be the first of three general strikes, which will be repeated on Wednesday, May 27, and Friday, June 5.

The new protest calendar also includes about fifteen territorialized stoppages, with two per area, ensuring that all public schools will have a total of five strike days, combining general and territorial ones. In addition, two massive mobilizations have been planned to open and close the protest cycle.

The unions have justified repeating the March strike model due to its success in participation and media coverage. This strategy allows the conflict to remain open and media attention for a month, avoiding the wear and tear that an indefinite strike would entail. A union spokesperson acknowledged the "dangers" of such a long mobilization but pointed out that "it is the administration that can prevent it".

The union organizations insist that the agreement signed by the Government with other unions, which represent a minority of the sector, "does not reverse the cuts" of 2010 nor does it respond to the real needs of schools and teachers. The situation has worsened with the Department of Education's intention to place Mossos d'Esquadra (Catalan police) in classrooms, a measure that the unions consider a "repressive element" and a sign of the critical situation in schools.
