Just hours before his union marches against the national government, CGT umbrella union grouping General Secretary Héctor Daer on Wednesday urged for leading Peronist leaders to "try" to "unite" against President Macri in the lead up to the 2019 October general and presidential elections.
"They must try to unite. They cannot give up in their attempts to achieve this," Daer told Futurock radio, when quizzed about leading contenders Cristina Fernández de Kirchner, Sergio Massa and Roberto Lavagna.
Despite the candidates "having nothing in common," Daer warned that what was at stake in October was workers' rights.
Macri "will target labour reform" if he were re-elected, the union leader said said.
Daer echoed similar concerns held by union leader Pablo Moyano about a potential Lavagna presidency.
"We cannot rule out a general strike this year because of the instability around this government," Daer added.
"We need to understand that this [unity] is what can get the country moving forward. We need to win and govern," the union boss added.
"We have an alternative to this government and the objective is on the electoral process. We have the highest expectations for [today's] protest. We think it's going to be huge," he said.
The protest begins today from Plaza Miserere in Once and will end at the Avenida 9 de Julio.
