The Confederación Regional Obrera Mexicana (CROM) (Spanish: "Regional Confederation of Mexican Workers") is a federation of labor unions in Mexico.
It was founded in Saltillo in 1918 at a congress of labor delegates called by Mexican President Venustiano Carranza. The federation, of which Luis Napoleón Morones was a major leader, marked a departure from the traditionally anarchist stance of Mexican labor to a nationalist position.
From its inception, the CROM was controlled by a small group of union leaders called Grupo Acción ("Action Group") who supported the post-revolutionary government.
After supporting President Carranza, the CROM was a key base of support for two of his successors, Álvaro Obregón and Plutarco Elías Calles. The political vehicle of the federation was the Mexican Labor Party. Under Obregón, the labor movement was co-opted as its leaders were appointed to posts within the government. By the end of Obregón's term, labor had abandoned its goal of destroying capital in favor of establishing a balance between capital and labor that would benefit workers. Labor leaders defended the government's right, established in Article 123 of the Constitution of 1917, to arbitrate labor disputes, since they felt that their interests were represented in the government.
Radical elements of the labor movement, horrified by the cooption, formed their own federation, the Confederación General de Trabajadores (CGT), in 1921. The result of the split was disorientation within the movement, and workers became disillusioned with both the CROM and the CGT. Nonetheless, workers won some rights, albeit at a gradual pace that did threatened neither the revolutionary government nor the growth of capitalism.
In 1921, in a prelude to the Cristero War, the Mexican Catholic Church declared membership in the CROM a mortal sin. The proclamation failed to deter Mexicans from joining the federation or participating in its street demonstrations.
Under Calles, the government gained even greater control over the CROM through its grip over Grupo Acción. The CROM essentially monopolized union membership, claiming over one million workers and five hundred organized peasants among its members. In reality, there were only about twenty thousand dues-paying members. Calles wielded influence over the CROM through Morones, whom he appointed the Minister of commerce and industry.
By 1928, however, Calles had become distrustful of Morones, who had presidential ambitions. He was also wary of labor's socialist interpretation of the Revolution. He broke the CROM's power by ordering the federal arbitrating bureaucracies to declare all CROM strikes illegal. The CROM's leadership had become so corrupt that it had lost its influence with the rank-and-file, and was thus unable to organize action in its favor.
Calles's successor, Emilio Portes Gil, began removing CROM officials from government positions. Vicente Lombardo Toledano, a dissident in the CROM, organized a faction called "Purified CROM" that left the federation in 1932, leaving the CROM to represent only a few unions in the textile industry. The Purified CROM became the Confederation of Mexican Workers (CTM) in 1936, allying with the populist President Lázaro Cárdenas and the ruling Party of the Mexican Revolution. In the following years, the CTM eclipsed the CROM.
The CROM continues to exist, and is the third largest labor federation in Mexico and supports the PRD
