Mexico’s president spent Friday presenting her second annual report in Oaxaca. Outside the hall, CNTE teachers were pushing through a security cordon to reach her.

The event was at the Guelaguetza auditorium, on the Cerro del Fortín above the city. CNTE Sección 22 marched on it while Claudia Sheinbaum was inside.

The CNTE teachers were stopped on the road up the hill, near the Hotel Victoria. El Imparcial de Oaxaca reported pushing, blows and rock-throwing.

Who Was Holding the Line

The two main accounts differ, and the difference matters. Aristegui Noticias reported that the CNTE teachers clashed with militants of the governing Morena party.

Those militants blocked access with metal barriers, according to that account. El Imparcial describes the line differently.

El Imparcial described the cordon as government workers and members of a transport organisation. Neither outlet has contradicted the other.

If party militants formed the cordon, a governing party physically blocked a union from reaching a public event. If it was state workers and transport operators, it was a different kind of mobilisation.

The teachers eventually advanced toward the auditorium. No injuries or arrests were confirmed by any outlet.

What the Interior Secretary Said

Rosa Icela Rodríguez was present at the confrontation site. She held talks with the leadership of Sección 22.

Her public comment was conciliatory. Everyone, she said, has the right to demonstrate, and the teachers were within their rights.

She added that they had been received the previous day. That is the standard formulation for saying a meeting already happened and produced nothing.

The union’s general secretary is Yenny Pérez Martínez. Sección 22 also blocked Avenida Juárez and Calzada Héroes de Chapultepec in the city.

What They Actually Want

The demands are national rather than local. The union wants the 2007 pension law repealed and the public pension system defended.

It wants the education reform abolished and with it USICAMM, the federal body that runs teacher recruitment and promotion. That system replaced the one dismantled in 2019.

It also wants what it calls effective attention to educational, labour and social problems in Oaxaca. That covers unpaid salaries and the regularisation of contract teachers.

The pension demand is the hardest. Mexico’s 2007 reform moved public workers from a defined-benefit system to individual accounts.

Reversing that would cost more than any government has been willing to commit. It is why the CNTE teachers keep marching and keep being received.

Why These CNTE Teachers Are Different

The CNTE is the dissident wing of Mexico’s national teachers’ union, organised in state sections. Sección 22 in Oaxaca is its strongest.

It has effectively co-governed Oaxacan education since the 1980s. It controls appointments, transfers and the school calendar in ways no other Mexican union does.

In 2006 a teachers’ strike in Oaxaca escalated into a months-long occupation of the state capital. That episode remains the reference point for both sides.

A national work stoppage this year left more than 1.4 million students without classes across six states, according to the education ministry. It counted 17,471 schools affected out of 61,930.

What Sheinbaum Said

Her speech did not address the protest. She announced that 1.73 million people in Oaxaca receive federal welfare payments.

She set out health and infrastructure commitments for the state. They include 1,600 clinics opening from January 2027 and three hospitals in a planned health complex.

The Tren Interoceánico and a development plan for the Mixteca also featured. Oaxaca is among the poorest states in Mexico and among the most reliably supportive of her party.

That is the tension the day illustrated. The state where Morena’s vote is strongest is also where its most persistent organised opposition comes from the left.
