Region 28 - Phoenix

Welcome to the Region 28 of the National Labor Relations Board. We conduct elections, investigate charges of unfair labor practices, and protect the rights of workers to act together, serving Arizona, New Mexico, and parts of Texas and Nevada from our regional office in Phoenix and resident offices in Las Vegas and Albuquerque. If you have questions or wish to file a charge or petition for election, please visit our office or call and ask for the Information Officer on duty. We can arrange to have someone speak with you in the language of your choice. We are also happy to provide speakers and materials to promote a greater understanding of the National Labor Relations Act.


This Regional Office participates in the NLRB’s Volunteer Field Examiners Program for undergraduate and graduate students.  The Volunteer FX interns assist in conducting unfair labor practice investigations, arranging representation elections, conducting elections and performing basic legal research. Volunteer Interns will work directly with agents and report to a supervisor who will guide them in handling case work and investigations. Interns may be briefed by senior officials from throughout the Region and Agency about the NLRB and the NLRA. Interns will be asked to produce written work products summarizing the results of investigations along with recommendations.  The Agency will work closely with participating schools to ensure class credit where permitted or desired and will provide on-the-job training as well as training on the NLRB through live and video presentations of the Agency’s Summer Intern Program and regularly scheduled Board Agent training.  Please click on the following link: Student Positions - Pathways and volunteer for more information.
