Mexico & Labour Relations
Where ghost unions and sweetheart contracts defined a system for 70 years
Mexico’s labour relations system has been shaped by one of the most unusual and troubling phenomena in the world of industrial relations: the protection contract (contrato de protección). For decades, ghost unions connected to the ruling PRI party signed collective agreements on behalf of workers who had never heard of the union, with terms set by management, designed to prevent genuine union organizing. The slow dismantling of this system — accelerated by the USMCA labour reforms of 2019–2020 — is one of the most significant labour law transformations underway in the Americas.
10 Things That Stand Out About Labour Relations in Mexico
- Mexico’s labour relations system was forged in the aftermath of the Mexican Revolution (1910–1917) and institutionalized under the ruling Institutional Revolutionary Party (PRI), which governed Mexico without interruption from 1929 to 2000. The PRI incorporated the major union confederations into its political structure, creating a corporatist system in which unions were arms of the party-state rather than independent worker advocates.
- The Confederation of Mexican Workers (CTM), founded in 1936 under PRI auspices, was the dominant union confederation for most of the 20th century. CTM leaders were guaranteed political positions and economic privileges in exchange for delivering labour peace and worker support for the PRI — a arrangement that entrenched corruption and suppressed genuine collective bargaining.
- One of the most powerful and controversial figures in Mexican labour history is Fidel Velázquez, who led the CTM for over 50 years (1941–1997). Velázquez was the archetype of the charrazo — the practice of imposing corrupt, management-friendly leaders on unions — and his longevity represented the durability of the corporatist labour system. Despite his reputation for serving PRI and employer interests, he was also genuinely skilled at maintaining working class support through selective patronage.
- The protection contract (contrato de protección patronal) is Mexico’s most notorious labour institution. A management-appointed union registers a collective agreement covering a workplace before workers are even hired, keeping the contract secret from them and preventing any genuine organizing. Estimates suggest that the majority of formally registered collective agreements in Mexico were protection contracts.
- The independent union movement in Mexico faced decades of suppression, with genuine organizers subject to physical intimidation, blacklisting, and legal harassment. The democratic union tendency (tendencia democrática) that emerged in the 1970s within official unions represented workers who sought to reclaim their unions from charros, often at great personal risk.
- Mexico’s labour law reform of 2019, passed by the López Obrador government, represented the most significant overhaul of the Mexican labour system since the 1930s. It required existing collective agreements to be legitimized through genuine worker votes, abolished protection contracts, created independent labour tribunals, and introduced federal conciliation centres to replace corrupt local labour boards.
- The USMCA (the 2020 successor to NAFTA), negotiated under pressure from the AFL-CIO and UFCW in the United States, included labour chapter provisions requiring Mexico to adopt the 2019 reforms and allow independent verification of their implementation. For the first time, a North American trade agreement included enforceable labour standards with real consequences for non-compliance.
- The elimination of protection contracts and legitimization votes produced significant results: hundreds of ghost union contracts were eliminated or replaced by genuinely negotiated agreements, and the CTM-affiliated unions lost their monopoly in multiple major automotive and manufacturing facilities as workers chose independent representation.
- Union density in Mexico is approximately 12–15% of formal sector workers, though the informal economy — which employs approximately 55% of the workforce — is almost entirely outside the formal labour relations system. The 2019 reforms have begun to transform the quality of collective bargaining in the formal sector, but extending genuine labour rights to informal workers remains a fundamental challenge.
- The new unionism emerging in Mexico — in automotive plants, call centres, and manufacturing facilities where workers have exercised genuine choice for the first time — represents one of the most hopeful developments in Latin American labour relations. International union observers and USMCA enforcement mechanisms have given independent Mexican unions an unusual degree of external support and scrutiny, creating conditions for genuine collective bargaining that have not existed in Mexico since before the PRI era.
