Mexico's Federal Labour Law guarantees equal pay for equal work where the job, working day and conditions are equal — not the broader equal-value standard — and requires no factor-based evaluation. Pay-transparency reform proposals are advancing but the core standard remains 'equal work'.
Mexico's wage-equality rule is among the oldest in this survey — and among the narrowest. Article 86 of the Ley Federal del Trabajo states the principle plainly: trabajo igual, salario igual — equal work, performed in the same position, the same working hours, and the same conditions of efficiency, must receive equal pay. It echoes the constitutional labor guarantee in Article 123, and it binds every employer in the country.
The qualifier is everything: the comparison runs only between materially identical situations — same job, same shift, same efficiency. Mexican law has no work-of-equal-value standard: no provision compares a female-dominated occupation against a different male-dominated one of equivalent demands, and consequently nothing in Mexican law requires job evaluation. Mexico ratified ILO Convention 100 in 1952 — one of the first countries to do so — which makes the seventy-year persistence of the same-work ceiling the defining fact of its pay equity regime.
Article 86 applies universally, enforced through the labor courts (and the post-2019 labor justice reform's new tribunals) alongside the anti-discrimination provisions of the LFT and the Ley Federal para Prevenir y Eliminar la Discriminación. Voluntary instruments exist around the edges — notably the NOM-025 workplace equality and non-discrimination certification, which addresses pay practices among broader equality criteria — but none converts the equal-work rule into an equal-value one.
Mexico completes the pattern visible across Japan, India, and Chile: early Convention 100 ratification, a genuine same-work guarantee, and a structural blind spot for occupational segregation — the mechanism that actually drives most of the gender pay gap. For multinational employers, Mexican operations are typically governed in practice by group pay equity standards far stricter than Article 86, because an equal-value audit run for the EU or Canada doesn't stop at the Mexican border. And with pay transparency advancing in the region — Brazil's enforced reporting regime most visibly — the legislative gap is increasingly conspicuous.
Mexico promised the equal-value principle in 1952 and legislated the equal-work rule instead. Employers who evaluate jobs analytically simply keep the promise themselves.

No. Article 86 of the Ley Federal del Trabajo establishes equal pay for equal work — trabajo igual, salario igual — performed in the same position, workday, and conditions of efficiency. That is a same-work standard; Mexican law contains no work-of-equal-value mandate and no job evaluation requirement.
That equal work, performed in the same job, working hours, and conditions of efficiency, must receive equal pay. The constitutional principle in Article 123 echoes it. Comparison is confined to materially identical situations.
Yes — Mexico ratified ILO Convention 100 in 1952, among the earliest ratifications. The Convention's equal-value standard allows comparing different jobs of equivalent demands, which Mexico's domestic equal-work rule does not.
Gender equality reforms have been recurrent — including NOM-025 workplace equality certification and periodic legislative proposals on pay gaps — but as of mid-2026 the operative wage rule remains Article 86's same-work standard, with no equal-value mechanism adopted.
