Establishing Our Collective Strength Mail Handlers employed by the USPS are covered by a National Agreement, which is our collective bargaining agreement covering a wide array of issues relating to wages, hours, benefits and working conditions. The NPMHU has a National Negotiating Team that meets with the Postal Service management several months before the contact expires. Based on suggestions submitted by rank-and-file Union members, the team proposes contract language to which the Postal Service responds, and through a concentrated series of discussions, and with the give and take of negotiation, they attempt to reach an agreement that works for everyone.
