David Nihill tells the story of Dublin's Grapefruit Ladies.On 19 July 1984, Mary Manning, a 21-year-old shop worker in the Henry Street, #Dublin outlet of #DunnesStores, refused to handle the sale of grapefruit from #SouthAfrica. She was joined by other workers, and the strike lasted until April 1987 when the Irish government banned the importation of South African goods.Manning and her colleagues gained global recognition, and personal thanks from #DesmondTutu and #NelsonMandela.
