Workers at Mexico’s Instituto Mexicano del Seguro Social (IMSS) have secured an 8% pay rise, a deal that was reached after a series of protests that directly confronted members of the ruling National Action Party (PAN). The increase exceeds the last offer rejected by the union by 1.2%, marking the most significant wage adjustment for the health‑social security system in recent years.

Background and political stakes

The IMSS is the nation’s largest public health and social security provider, covering more than 60 million people and employing over 400,000 staff. Zoé Robledo, the health secretary overseeing the agency, announced the wage increase in a televised briefing, framing it as a response to “the legitimate demands of our workers.” The announcement comes at a time when the PAN‑led administration is under pressure to balance fiscal discipline with social spending ahead of the 2027 elections.

Negotiations and the 8% agreement

According to La Jornada, the union’s final settlement offers an 8% raise, which is 1.2 percentage points higher than the previous proposal that the workers had collectively rejected. The newspaper noted that the higher figure was accepted after intensive talks that included a threat of a wider strike, though no formal strike vote has been reported.

El Economista added that, despite the wage concession, the government has maintained a freeze on new hires under the so‑called “Modalidad 40” contract. This hiring freeze, described as a measure to “contain public‑sector payroll growth under the current economic conditions,” affects a cohort of workers who would otherwise be brought in on a semi‑retirement, part‑time basis.

Protests and political confrontation

Demonstrations escalated when IMSS employees set up a camp near a PAN conference venue. La Jornada reported that workers shouted “¡fuera oportunistas!”—“Out, opportunists!”—directed at party officials attending the event. The confrontation highlighted growing frustration among rank‑and‑file staff, who accuse the ruling party of using the hiring freeze as a political tool rather than a genuine fiscal necessity.

“The 8% increase we have obtained is 1.2 percentage points higher than the offer that was turned down,” the union’s spokesperson told La Jornada.

The episode has drawn criticism from opposition parties, which argue that the wage hike could exacerbate Mexico’s already strained public finances. Analysts note that the IMSS payroll accounts for roughly 12 % of federal expenditures, and any rise in salaries must be balanced against the need to fund expanding health services.

Government officials have signaled that the wage settlement will be financed through internal budget reallocations, while maintaining the hiring freeze as a “temporary measure” pending a broader review of public‑sector compensation. The administration has not ruled out the possibility of revisiting the Modalidad 40 freeze later in the year, depending on economic indicators and fiscal space.
