Day 601 — CNTE Teachers Launch Strike and March in Mexico City; Mega-March Planned for June 1 During FIFA World Cup

On May 25, 2026 (Day 601), the Coordinadora Nacional de Trabajadores de la Educación (CNTE), the dissident national teachers' union, launched an indefinite strike and march action in Mexico City, disrupting traffic around the Zócalo and key central corridors. SECTION 22 OAXACA STRIKE: The CNTE's Section 22 — the largest and most militant section, based in Oaxaca — struck simultaneously, suspending basic education classes throughout Oaxaca state. Classes in Mexico City continued normally; the CNTE's CDMX sections joined the march but have not yet called a formal classroom strike. DEMANDS: (1) Abrogation of the 2007 ISSSTE Law reform, which overhauled teacher pensions and is viewed by the union as reducing retirement benefits for public sector workers who enrolled after the reform. (2) Salary increases above the 2026 inflation rate. (3) Reinstatement of workers dismissed under previous government crackdowns on union activity. MEGA-MARCH JUNE 1: The CNTE announced a national mega-march toward the Zócalo on June 1, 2026 — deliberately timed to coincide with international attention on Mexico City during the opening phase of the FIFA World Cup 2026 (which Mexico is co-hosting). The union plans to establish an indefinite encampment at the Zócalo, as CNTE has done in past mobilizations (2013, 2016). GOVERNMENT RESPONSE: Sheinbaum stated at her May 25 mañanera that dialogue through SEP and SEGOB is open and ongoing; she did not signal any intention to make concessions on the ISSSTE law abrogation, which would have significant fiscal implications. CONTEXT: The CNTE's strategic timing reflects a broader pattern of civil society mobilizations that have tested the Sheinbaum administration throughout 2026 — transportistas blockades (April), feminist marches (March 8), and now teacher strikes — all coinciding with periods of heightened international visibility, including the USMCA talks and the World Cup.
