Step-by-step explanation:
The agreements between MNCs (multinational corporations) and international trade union organizations which commit the companies to observing standards and principles throughout their worldwide operations, known as codes of conduct, have increased in recent years. These agreements are called International Framework Agreements (IFAs).
IFAs are important tools for ensuring that MNCs adhere to specific labor standards and practices across all countries in which they operate. These are different from broader trade organizations or agreements like the World Trade Organization (WTO), European Coal and Steel Community (ECSC), North American Free Trade Agreement (NAFTA), or regional trade agreements. The goal of IFAs and related initiatives like the United Nations Global Compact is to promote a sustainable and equitable global trade environment that respects labor rights and ensures fair working conditions.
