The dismissal of half of the political structure of the Matanza Riachuelo Basin Authority (ACUMAR) generated a mobilization of the ATE unions. There, in addition, various bomb threats were recorded.

The unions claim that the layoffs were "political." The plant had grown by 100% between 2019 and 2023, the authorities indicated. ACUMAR is currently led by Lucas Figueroa, who had already served in the position during Mauricio Macri's administration.
