Argentina ground to a near standstill Thursday after the country’s largest labor federations launched a one-day general strike to protest President Javier Milei’s sweeping labor reform bill, escalating a high-stakes confrontation between the libertarian administration and entrenched unions ahead of a decisive congressional debate.

Banks shuttered their doors, public schools suspended classes, buses and subway lines halted service, and airlines canceled hundreds of domestic and international flights. Public hospitals limited operations to emergency procedures, postponing scheduled surgeries and routine appointments. The coordinated stoppage represented one of the most disruptive nationwide labor actions since Milei took office, underscoring the organizational strength of unions that have long shaped Argentina’s political and economic landscape.

The strike coincided with deliberations in the lower house of Congress over Milei’s flagship proposal to overhaul labor regulations that date back more than half a century. The Senate granted preliminary approval to the measure last week, but its path to final passage remains uncertain. Should the Chamber of Deputies endorse the revised bill, it must return to the Senate for a final vote due to last-minute amendments introduced after the initial approval.

Milei has framed the reform as a cornerstone of his broader economic transformation agenda. Since assuming office, his administration has pursued aggressive fiscal consolidation measures aimed at stabilizing an economy long battered by triple-digit inflation, chronic budget deficits and currency volatility. While the government has succeeded in curbing inflationary pressures and restoring a measure of macroeconomic discipline, critics argue that the benefits have yet to translate into improved living standards for many Argentines.

Unemployment remains stubbornly high, real wages have stagnated and economic growth has lagged expectations. Against that backdrop, unions have found fertile ground to mobilize workers concerned about the erosion of hard-won labor protections.

The proposed legislation would significantly alter the balance between employers and employees. Key provisions include reducing severance payments, limiting the scope of the right to strike, easing dismissal procedures and allowing for extended 12-hour workdays under certain contractual arrangements. Another controversial clause — introduced late in the legislative process — would cut in half the salaries of employees on medical leave for non-work-related injuries or illnesses, prompting backlash from opposition lawmakers and forcing the government to amend the Senate-approved version.

Cristian Jerónimo, a senior leader of the General Confederation of Labor (CGT), Argentina’s largest union umbrella group, described the bill as a regression that prioritizes employer flexibility over worker security. “The labor reform project is entirely regressive,” he said during a press conference announcing the strike, arguing that it undermines fundamental protections embedded in Argentine labor law.

For decades, Argentina’s labor code has been regarded as one of the most protective — and costly — in Latin America. Employers frequently cite high severance obligations and rigid hiring rules as deterrents to formal job creation. Roughly 40% of the country’s estimated 13 million registered workers are union members, according to labor estimates, and many unions maintain close ties to Peronism, the labor-oriented political movement that dominated Argentine politics for much of the past century.

Milei contends that reform is essential to modernize the economy, attract foreign investment and reduce the prevalence of informal employment, which accounts for approximately two in five workers nationwide. By lowering labor costs and increasing contractual flexibility, the administration argues, companies will be incentivized to hire formally, expanding the tax base and improving productivity.

The political stakes are high. The labor reform represents the first major legislative test of Milei’s governing strength since his party, La Libertad Avanza, consolidated its position in last year’s midterm elections. Although the libertarian coalition has gained momentum, it lacks an outright majority in Congress, requiring delicate negotiations with allied blocs to secure passage of contentious measures.

Complicating matters, the strike unfolded while Milei was abroad in Washington attending an international meeting hosted by U.S. President Donald Trump. The timing underscored the domestic challenges facing the Argentine leader as he seeks to deepen international partnerships and project economic reform credentials on the global stage.

If the lower house approves the amended bill, senators will be asked to cast a final vote next week. Lawmakers across party lines have signaled that the controversial medical leave provision could become a flashpoint, potentially altering the bill’s prospects.

Thursday’s nationwide shutdown demonstrated that organized labor retains formidable mobilization capacity despite shifting political winds. Whether Milei’s reform effort can overcome union resistance and legislative hurdles will shape not only Argentina’s labor market framework but also the trajectory of his broader economic overhaul.

As Congress debates, the country finds itself at a crossroads between preserving longstanding worker protections and embracing a more market-oriented labor regime — a choice that could redefine Argentina’s economic model for years to come.
