Labor standards, such as the prohibition of child labor and forced labor, discrimination, and inhumane treatment, along with the right to freedom of association, fair remuneration, protection against health risks, and limitations to working hours, are human rights codified in more detail by the International Labor Organization. Although core labor standards are protected in most countries, labor rights violations are observed internationally. The most affected are workers in countries where labor laws are rudimentary, the rule of law is weak, and formal employment is scarce. Therefore, companies with global supply chains have resorted to issuing codes of conduct that make some labor standards obligatory for themselves and their suppliers. Despite regular monitoring and remediation actions, improvements in working conditions remain piecemeal rather than systematic. To ensure that more companies work on improving labor standards in their international supply chains, several countries have issued disclosure and due diligence laws. However, obstacles resulting from limited organizational resources, competition, price pressure, poverty, and weak institutions continue to threaten labor standards.
