Salvador Allende began his presidency at the head of the Popular Unity (Unidad Popular) coalition. The new government promised major economic and social changes, and organized labor became a key ally and pressure group in pushing those changes forward. This set the stage for rapid growth in workplace activism and conflict with employers and opposition parties.
Workers took over the Yarur (Machasa) textile factory, an action that became a well-known example of workplace mobilization during the Allende years. The occupation reflected demands for better working conditions and for bringing key private firms into the state-led “social area” of the economy. Events like this increased union confidence but also deepened conflict over property rights and government authority.
Chile’s Congress approved a constitutional reform to nationalize the major copper mines, and the reform was promulgated as Law 17,450. Copper was Chile’s most important export, so the decision affected jobs, state revenue, and the wider economy. For many unions, nationalization symbolized stronger worker influence over national development, while critics feared economic retaliation and instability.
A major demonstration in Santiago—often called the “March of the Empty Pots and Pans”—protested food shortages and distribution problems. While not a labor action, it mattered to the labor movement because it signaled growing social conflict around wages, prices, and access to basic goods. The rising pressure on supply and prices pushed workers and neighborhood groups toward new forms of organization around distribution.
The Central Única de Trabajadores (CUT), Chile’s main labor federation, held its Sixth National Congress. The congress reflected how closely the CUT was tied to debates about the direction of the Popular Unity project. It also helped consolidate labor’s role in national politics at a time when workplace disputes and economic strain were increasing.
Law 17,594 recognized the CUT’s legal personality and provided mechanisms to fund its activities. It also expanded the CUT’s formal participation in national economic planning and in the administration of firms. This tightened the labor federation’s connection to the government—strengthening worker influence, while also increasing political polarization around unions.
The government formalized the Juntas de Abastecimiento y Control de Precios (JAP), neighborhood-level committees meant to help control prices and distribute food. These committees connected workplace politics to everyday survival, since shortages and inflation affected real wages. For many working-class communities, the JAPs became an important arena for participation; opponents criticized them as political control over distribution.
The first cordón industrial (industrial belt) is often dated to the Perlak factory takeover and subsequent coordination among nearby workplaces. Cordones linked multiple factories to defend production and organize collective action, especially during employer lockouts and supply disruptions. They became a hallmark of “worker power” efforts that sometimes worked with, and sometimes pressured, the government and established unions.
A nationwide stoppage—often called the October 1972 strike or truckers’ strike—disrupted transportation and supply chains. The crisis intensified workplace mobilization and encouraged workers and unions to support emergency production and distribution efforts. It also hardened political divisions, with labor organizations increasingly seeing the conflict as a fight over whether the government could govern.
Workers at the El Teniente copper mine began a strike that lasted weeks and became one of the most serious labor disputes the Allende government faced. The conflict centered on wage adjustments in a high-inflation economy, and it had major economic and political impact because copper was vital to national income. The strike also exposed tensions inside the labor movement, including differences between unions, political parties, and the government over strategy.
An armored unit attempted to overthrow the government in what became known as the Tanquetazo. The failure did not end the crisis; instead, it increased fears of further military action and pushed many workers to expand workplace and neighborhood defense and coordination. For the labor movement, the episode underscored how political conflict was now threatening democratic institutions and union gains.
The Chamber of Deputies approved a resolution accusing the government of serious breaches of constitutional and legal order and calling on authorities to end those situations. This public institutional clash further escalated the national crisis surrounding governance, the economy, and control of workplaces. For unions and worker organizations, it signaled that the conflict was moving beyond strikes and negotiations toward a showdown over state power.
The armed forces overthrew President Allende on September 11, 1973, ending the Popular Unity period. The coup quickly dismantled many worker-led institutions and severely repressed left-wing parties and labor organizations. This marked a sharp break in workers’ rights organizing: what had been mass participation and workplace coordination shifted into survival under authoritarian rule.
Soon after the coup, the military government abolished the JAP system that had helped organize local food distribution and price control. The move removed a key working-class and neighborhood institution created during the Allende period. It also signaled the broader rollback of participatory structures linked to labor and Popular Unity policies.
Following the coup, the CUT was dissolved by the new military authorities, formally ending the main national labor federation that had dominated Chilean union life for decades. The dissolution closed the Allende-era arc of legally empowered, politically influential union organizing. It also set the conditions for a new labor environment defined by repression and state control rather than mass collective bargaining and workplace democracy.
