On Thursday, a protest against the labor reform led by leftist groups and combative unions took place in Plaza de Los Dos Congresos, marked by incidents of police confrontation. Protesters attempted to break through barricades set up by police, which responded with tear gas to disperse the crowd. The turnout for the protest was not significant, as major organizing groups had disbanded before the afternoon, although some protesters remained until late in the night. By the end of the day, authorities reported that fourteen individuals had been detained following an operation to clear the plaza.

Before the protest began, the Federal Police had erected barriers to protect the Parliament, placing security measures around the entry square and blocking surrounding streets. In contrast, Avenida 9 de Julio remained open to traffic, allowing some flow amidst the heightened security. Tensions were high as protesters chanted against the government's labor overhaul, with one demonstrator shouting about the ongoing voting in Parliament favoring the proposed reforms. The police's preemptive measures indicate a tense atmosphere and a government ready to curb opposition to its legislative agenda.

This protest reflects broader discontent among labor groups and leftist organizations in Argentina regarding controversial reforms aimed at labor market flexibility. As the government pushes for significant changes, such clashes highlight the friction between state authorities and civil society, suggesting an increasingly contentious political climate. The significant number of arrests could be seen as a warning to future protests, indicating that the government will not tolerate disruptions amid these legislative efforts.
