BUENOS AIRES, Argentina (AP) — Argentina’s libertarian President Javier Milei faced a one-day general strike Wednesday protesting his decree targeting unions as well as his proposals for economic and labor law changes, showing that his opponents are wasting no time in trying to derail his austerity agenda.

The biggest union, known by its acronym CGT, organized the strike and was joined by other unions. Strikers took to the streets in the capital, Buenos Aires, and other cities across the country, joined by social groups and political opponents, including the Peronist party that dominated national politics for decades.

“His capacity to keep the Argentine public on board will be tested and is being tested already, and that’s what you’re seeing right now,” Gedan said, saying the president has “given opponents a lot of weapons because he has moved so quickly and dramatically” to address Argentina’s problems.

Gedan said a one-day strike isn’t “an existential threat” for the Milei presidency, but added: “Really the question is if this is a sign of what’s to come.”
