Human Rights Watch The United States Senate should pass the Protecting the Right to Organize Act (PRO Act), five human rights and labor groups said today in releasing a question-and-answer document about the issue. The Senate should seize on a once-in-a-generation opportunity to tackle rampant economic inequality by empowering workers and building a more just and human rights-based economy. The 16-page document, “Why the PRO Act Matters for the Right to Unionize in the United States” examines how the PRO Act would bring the US closer to meeting its obligations under international law by eliminating many of the barriers that prevent workers from exercising their rights to organize a union. Protecting these rights is critical to reducing economic inequality, as it allows workers to bargain collectively for fair wages, adequate benefits, and safe working conditions, reducing power imbalances between workers and employers. US President Joe Biden has pledged his support for the PRO Act, which the US House of Representatives passed on March 9, 2021.
