Respect for labour rights is a basic and fundamental pillar of responsible business conduct (RBC) and human rights due diligence (HRDD). They are also an integral part of social auditing which serve as one of the tools available to assess, evaluate and ultimately improve suppliers' performance in respecting labour rights in line with national legislation and as expressed in international labour standards (ILS). Understanding ILS and the guidance they provide is critical to enhance the effectiveness of social auditing, especially in light of the rapidly developments in the areas of RBC and HRDD that significantly alter expectations towards business practices and the role of social auditors. ILS are international law and form part of the international human rights norms and standards landscape. They provide the overall framework and guidance for business on interpreting and analysing conditions of work and employment in conjunction with local legislative frameworks governing the world of work. This course aims to enhance the capacities, knowledge and sense of purpose of social auditors to perform social audits based on a deeper understanding of international labour standards, the brands legal due diligence requirements, and the business and human rights agenda. It will clarify auditors' guidance on the linkages between sustainable development, decent work and responsible business, based on the expectations expressed in international labour standards (ILS).
