This 4th annual report from the Global Social Service Workforce Alliance includes a multi-country, four region review of the state of the social service workforce. Through Alliance-led mappings and assessments in three regions in collaboration with UNICEF, and information from mappings and assessments in a fourth region, this report consolidates trends and data and makes recommendations for better planning, development and support to this frontline workforce. The report also makes connections to the Alliance's Call to Action for Strengthening the Social Service Workforce to Better Protect Children and Achieve the SDGs. The data and findings are intended to build the evidence base in support of advocacy efforts to gain government and stakeholder commitments for strengthening the social service workforce. The report was launched at the 6th Annual Social Service Workforce Strengthening Symposium on 7 May 2019.
