Under principle 6 of the UN Guiding Principles on Business and Human Rights, states should promote respect for human rights by business enterprises with which they conduct commercial transactions. The same approach might be found in the Action Plan on the European Pillar of Social Rights adopted on 4 March 2021, which encourages EU member states to "promote international labor standards, decent work, and social inclusion." The seminar will bring together experts from different countries to establish the best practices in the formulation of labor clauses in public procurement and controlling compliance.
