International labor unions are organizations that represent workers' interests across national borders. They aim to improve working conditions, wages, and rights for employees globally. By uniting various national unions, these organizations can advocate for labor rights on an international scale, influencing policies and practices in different countries. These unions often collaborate with other groups, such as non-governmental organizations and international organizations like the United Nations or the International Labour Organization. Through collective bargaining and solidarity actions, international labor unions strive to address issues like child labor, discrimination, and unsafe working conditions worldwide.
