This forum, held 12-13 September 2017 in London, was the first gathering of the Alliance 8.7 global partnership focusing solely on the role and engagement of Civil Society Organisations (CSOs). The forum brought together over 60 leaders of organizations working to end child labour and modern slavery from 20 countries across the globe, the majority from the South, to share their experiences, and to explore opportunities to engage with Alliance 8.7 and ways they can collaborate more broadly. The forum was made possible through the generous support of the US Department of Labour. The conference was designed to allow maximum participation and discussion from the CSOs. It was structured around Q+A discussions and small, break out groups to enable all participants the opportunity to ask questions, deepen understanding and contribute ideas towards their involvement in Alliance 8.7.
