This article investigates the justiciability of labour human rights from a critical perspective, grounded in critical legal theory and the critical theory of human rights, according to Herrera Flores. It aims to affirm their superior foundation and propose ways to update labour procedure in accordance with international human rights treaties. The analysis considers the centrality of effective judicial protection, broad access to justice, and the right to a simple, prompt, effective, and free remedy as material conditions for the realization of economic, social, and cultural rights, as established in the Universal Declaration of Human Rights, the International Covenant on Civil and Political Rights, the International Covenant on Economic, Social and Cultural Rights, and the American Convention on Human Rights.
