BUENOS AIRES, ARGENTINA — Activity stopped Dec. 3 at various grain-processing plants north of Rosario, Argentina, due to a strike that started in the early morning, the CIARA crushers chamber said, according to Reuters.

The SOEA oilseed workers union is seeking bonus payments for working during the coronavirus (COVID-19) pandemic.

Initially, the group said the work stoppage would last 24 hours but later said it would last longer. Workers had a strike in October over the same issue.

Union members are supposed to meet Dec. 5 to decide on the next step, SOEA said.

“The San Lorenzo (plants) are stopped,” Gustavo Idígoras, president of CIARA, which represents major crushing companies, told Reuters. In Puerto General San Martín and Timbúes, SOEA union workers were working part-time.

Cargill, COFCO International, Terminal 6, a joint venture between Bunge and the local AGD, and Argentina’s Buyatti have crushing plants in San Lorenzo, with a daily processing capacity totaling 35,000 tonnes.
