The International Chamber of Shipping (ICS) and the International Transport Workers’ Federation (ITF) are calling upon ship captains across the world to sound their ships’ whistles when in port at 1200 local time on International Workers’ Day, 1 May 2020, recognised in many countries around the world to celebrate and acknowledge the contribution of workers.

The initiative is especially seen in support of the ICS-ITF campaign to facilitate crew changes. It follows the ‘Horns of Hope’ solidarity campaign initiated by Abu Dhabi Ports, which calls upon ports worldwide to allow ships in port to sound their horns every day at 1830 local time, in support of all critical workers, including port workers and seafarers.
