Thousands of people marched in Buenos Aires and in several cities against the reform projects of Javier Milei's government.
This took place amid a strike called by the main umbrella unions of the country: the CGT and the CTA.
Social, political, student, feminist and human rights organizations participated in the mobilization.
The central rally was at the gates of the National Congress, before a massive crowd who demonstrated against the so-called "Omnibus Law".
The text of more than 600 articles includes reforms in economic, administrative, fiscal and legal matters.
It also deregulates the labor, health, transportation and even football clubs markets and enables the privatization of more than 40 public companies.
The bill received this week the partial support of the opposition to be debated next week in the Lower House.
The demonstration was against this initiative and against a decree that Mr Milei signed in December to repeal more than 300 laws.
In yesterday's protest, one of the leaders of the CGT, Héctor Daer, denounced that the official plans "destroy workers' rights and the unions".
Another union leader who spoke was Pablo Moyano who asked the legislators "not to betray the workers" and to reject the official project in Congress.
Moyano also warned that the Minister of Economy Luis Caputo "will be carried on his shoulders, but to be thrown into the Riachuelo", the river south of the capital.
For these expressions, he was later denounced before the courts for threats.
The government, in turn, criticized the organizers of the march and assured that the strike had low support.
Security Minister Patricia Bullrich published on X: "Mafia trade unionists, complicit judges and corrupt politicians, all defending their privileges".
"There is no strike that can stop the National Government", she said.
Meanwhile, yesterday Courts accepted a request from the CGT and ordered the suspension of the labor articles of the presidential decree until they are debated in Congress.
