BUENOS AIRES, ARGENTINA — The labor union representing Argentina’s grain port workers announced on Sept. 28 that it would stage a 24-hour walk-off beginning at midnight after failing to reach a collective work agreement with the business chamber that represents private port owners, according to the MercoPress.

The union, which represents inspectors who check the quality of grains before they are loaded onto ships, said in a Sept. 27 statement that it called on all workers to “cease all activity in ports throughout the country.”

The union said it planned to meet with Labor Minister Claudio Moroni on Sept. 29 to discuss possible terms of an agreement with the Private Ports Chamber, according to MercoPress.

Argentina is the world’s top exporter of soybean meal and the No. 3 shipper of soybeans and corn.
