The Pittsburgh Metro Area Postal Workers Union was granted an AFL-CIO Charter on August 1, 1975. We currently represent 2,000 bargaining unit employees in the USPS Clerk, Maintenance, and Motor Vehicle Service Crafts.

We are the largest local in Pennsylvania, the 12th largest in the country, and are more than 90% organized.

USPS Offices under our jurisdiction include the Pittsburgh Processing and Distribution Center, Bulk Mail Center, and the Logistics and Distribution Center. We also represent the Pittsburgh Stations and Branches and more than 250 Associate Offices.

Our jurisdiction spreads to the New York, West Virginia, and Ohio borders and eastward to Route 219 and beyond. Our list of offices continues to grow as Member-At-Large Offices merge with PMAPWU.

In addition, PMAPWU has an officer that provides representation for Pennsylvania Postal Workers Union (PPWU) offices in Western Pennsylvania.
