The Macri administration has summoned business and union leaders to Government House in an attempt to thwart the CGT's plans to carry out a 36-hour strike during the G20 leaders summit.
"It is very probable that we will carry out strike activity before the end of the year", Héctor Daer, one of the CGT's co-secretary generals, said last week.
"The government went to the IMF (International Monetary Fund) on its knees", Dear claimed. He said the union movement "no longer has any room to move".
Production and Labour Minister Dante Sica will receive CGT confederation leaders, and representatives from of the Argentine Industrial Union (UIA) and the Medium-size Business Confederation of Argentina (CAME).
Unions will demand the government reopen collective wage bargaining negotiations in light of the surge in inflation and the US dollar, as well as call for the payment of a special bonus for workers to compensate for the reduction in real wages, the Todo Noticias news channel reported.
They are also calling for a pact with the government to address mass lay-offs in both the private and public sectors, and for annual bonuses to be exempt from income tax, which the government had previously rejected in June.
Some of the country's more powerful unions have secured wage increases above 40 percent, including the Teamsters, Hygiene and Banking sectors.
Several sectors, particularly in the public sphere, remain engaged in conflict with national and provincial governments.
