Since 1908, the National Association of Postal Supervisors has promoted the interests of postal managers, supervisors and postmasters as well as lobbying for the general welfare of the United States Postal Service.
NAPS is a management association, not a union. NAPS is unique among federal management associations in that its rights are statutory, with a high level of detail concerning its relationship with USPS. NAPS' rights are listed under Title 39 of the US Code, Section 1004.
Headquartered in Alexandria, VA, NAPS is very active in the national political arena. NAPS' political action committee, SPAC, has donated over $300,000 annually to various political campaigns and that number continues to grow every year. NAPS has an active letter-writing campaign and has authored several issue papers concerning NAPS issues and issues concerning the Postal Service.
