BUENOS AIRES, ARGENTINA — A seven-hour strike by customers officers on June 8 is likely to affect grain exports from Argentina, Reuters reported, citing the port manager.

The customs officials are pushing for priority access to COVID-19 vaccinations. Last month, tugboat captions walked the job to pressure the government into giving them vaccines.

Argentina is the world's No. 3 exporter of corn and is a top supplier of soymeal livestock feed used to fatten hogs and poultry from Europe to Southeast Asia.

The short work stoppage wasn’t expected to have a major impact on shipments, but they could get bogged down if longer strikes are called.

The Argentine Union of Customs Personnel said in a statement on June 4 that the strike will happen in the middle of the work day on June 8.

"Depending on the result, union actions may intensify after Tuesday," the labor organization said.
