Postal Supervisors, Managers, and Postmasters Fairness Act of 2026

This bill aims to enhance the negotiation process for pay and benefits for supervisory and managerial personnel within the United States Postal Service. It mandates that the Postal Service provide a written proposal to supervisors' and postmasters' organizations at least 60 days before an existing pay decision expires or 60 days after a collective bargaining agreement affecting these personnel is reached. The legislation requires all parties to actively work towards resolving any differences concerning these proposals through established dispute resolution procedures. Furthermore, it strengthens the dispute resolution process by making the final determination of a panel binding on the Postal Service, the supervisors' organization, and the postmasters' organization, ensuring a conclusive outcome for pay policies and fringe benefit programs.
