On June 9, 20 union members at San Fernando were arrested for taking part in a peaceful picket in front of the plant protesting the termination of their elected leaders. The protesting workers wore masks, maintained physical distancing and had agreed on procedures with the local police. Despite this they were arrested. They were released after several hours with charges dropped following the intervention of Alfredo Marañon, who defended the action as taking place in the context of an ongoing labour dispute.
