The CGT trade union body had challenged the changes, which technically took effect last Friday, on grounds that they erode basic worker protections such as the right to strike and parental leave, Paralel.Az reports citing France24.

The three judges of Argentina's labor appeals chamber froze elements of Milei's decree which, among other things, increased the legal job probation period from three to eight months, reduced compensation in case of dismissal, and cut pregnancy leave.

Judge Alejandro Sudera questioned the "necessity" and "urgency" of the decree Milei signed on December 20 -- just days after taking office -- and suspended the measures until they can be properly considered by Congress.

Some of the measures appeared to be "repressive or punitive in nature" and it was not clear how their application would aid Milei's objective of "creating real jobs," Sudera added in a ruling distributed to the media.
