What was a key challenge faced by the International Labour Organization?

The International Labour Organization (ILO) has historically had a key challenge in its ability to influence national policies and labor laws largely through moral persuasion rather than enforceable mandates. It was established to promote social justice and fair labor standards, but one of its limitations has been that it relies heavily on member states' willingness to adopt its conventions and recommendations. As a result, when member countries do not comply or take action based on ILO recommendations, the organization lacks mechanisms to enforce compliance. This situation emphasizes the challenge of influencing sovereign nations that may prioritize their own domestic concerns over international labor standards.

The other options do not accurately reflect the core challenges faced by the ILO. The organization has had various levels of funding from member states, has had member countries since its inception, and has been capable of developing new treaties and conventions, even if its ability to enforce them is limited.
