This bill, titled the Fair and Open Competition Act of 2025, aims to ensure open competition and maintain Federal Government neutrality regarding labor relations on federal and federally funded construction projects. Its core purpose is to prevent executive agencies from requiring or prohibiting contractors and subcontractors from entering into agreements with labor organizations. The legislation also forbids discrimination against bidders based on their affiliation or non-affiliation with labor organizations, thereby promoting economical project administration and expanding job opportunities for all businesses. The prohibition applies to contracts awarded and subcontracts made on or after the bill's enactment, with a mandate for the Federal Acquisition Regulation to be revised accordingly within 60 days. While agencies cannot mandate or prohibit such agreements, contractors and subcontractors are explicitly allowed to voluntarily enter into them. Exemptions are permitted only under specific "special circumstances" like averting an imminent threat to public health or safety or serving national security, but not due to labor disputes. Additionally, projects with existing labor agreements and awarded contracts prior to the Act's enactment may also be exempted.
