On this day, 9 July 1984, a national dockers’ strike was called in the UK in protest at the use of unregistered dockers to unload iron ore at the Immingham dock on the Humber, which had been blacked by the dockworkers in support of coalminers who were also on strike. Unfortunately the strike was broken when self-employed lorry drivers blockaded passenger ferries in Dover in protest at not being able to transport their goods and local union shop stewards called off the action fearing violence. The following day dockers around the country voted to return to work.
