The National Emergency Meical Services Association (NEMSA) is a registered labor union and California non-profit mutual benefit corporation. The bulk of NEMSA’s membership consists of emergency medical technicians (EMTs), paramedics and critical care nurses (CCT-RN) however NEMSA also represents EMS Dispatchers and Call Takers, Vehicle Service Technicians and support staff, and other EMS related support staff. NEMSA is the largest independent EMS union in the United States that represents EMS professionals. Because of NEMSA’s independence and industry specific focus, NEMSA is considered to be a “craft” union. In some cases however, NEMSA has temporarily allied itself with other unions(I.E.Sunnyvale,CA Public Safety Officers Association, PSOA, 2007/ International Association of Firefighters, IAFF, Boston,MA,2007) to accomplish specific joint-interest objectives.
