Prior to the implementation, unions sought a court injunction to halt the decree's enforcement, expressing concerns over the erosion of labour protections, which was ultimately rejected, leading to the scheduled implementation on Friday.

Milei's decree, set to take effect, raises questions about its legitimacy, especially given his party's limited representation in the legislature, raising concerns about the bypassing of legislative processes.

Union leaders emphasised on the importance of a president respecting the separation of powers, advocating for workers' rights and legal recourse against unconstitutional measures.

Although largely peaceful, clashes between a small group of protesters and the police disrupted the demonstration, leading to confrontations and police intervention, resulting in some journalists being caught in the scuffle.

Protesters voiced concerns against potential state-run industry privatisation, expressing discontent with proposals perceived to favour business interests over public welfare.

Since assuming office, Milei has introduced drastic economic changes, including currency devaluation, subsidy cuts, job terminations, and proposed legislative alterations, aiming to overhaul the country's economic landscape.

The General Labor Confederation denounced Milei's decree as a regressive labour reform undermining union activities, viewed as detrimental to workers and beneficial to business interests.

Milei's administration permitted demonstrations but issued warnings about impeding public aid payments for road blockades. Additionally, restrictions on protesters carrying items, covering faces, or bringing children were enforced.

While facing widespread opposition and protests, Milei's reforms garnered support from Argentina's Business Association, labelling the measures as crucial in addressing state size and mitigating consequences from years of budget deficits.
