The ILO remains committed to the continuous engagement with workers organizations on the UN reforms in general and more particularly on the role of Workers’ Organisations in the formulation, implementation, monitoring and evaluation of UN Sustainable Development Cooperation Frameworks (CFs) at national level. Against this background, the ILO's Bureau for Workers' Activities (ACTRAV) developed a reference manual for trade unions emphasising their political and developmental role in the UN sustainable development. The manual explains the UN country level development processes such as Common Country Analyses (CCAs) leading up to the consolidation and adoption of the Cooperation Frameworks. The expected role of trade unions and how they can promote the ILO normative agenda, International Labour Standards, decent work priorities as well as the national development strategies in line with the global sustainable development agenda 2030 (SDGs) is stressed.
