The Tug Sailors Union has arranged a 48 hour walkout from midday on 17 July, a statement said.

Its actions will impact principle tug services at all Argentinian ports, the statement added

It represents the latest round of industrial disputes to impact Argentinian shipments.

Only last week Urgara, a union made up of cargo controlling surveyors, halted work at the Buenos Aires province ports of Necochea and Bahia Blanca.
