This bill amends federal law to significantly alter the landscape of collective bargaining agreements for federal employees, granting a new President the authority to terminate any provision of an existing agreement upon taking office. It further stipulates that any provision within a collective bargaining agreement found to conflict with a presidential rule, executive order, or other presidential directive will be deemed unenforceable. This determination, which can be made by the President or an agency head, effectively prioritizes presidential actions over conflicting labor agreement terms. Agencies are required to provide written notification to the relevant exclusive representative when such terminations or conflict determinations are made, ensuring transparency in these actions.
