UAW Local 5810 was the labor union representing postdoctoral researchers and academic researchers at the University of California.[1] It is an affiliate of the International Union, United Automobile, Aerospace and Agricultural Implement Workers of America (UAW) or AFL–CIO. It was merged into UAW Local 4811 in March 2024 when the UAW International Executive Board voted to approve the amalgamation of academic student employees, graduate student researchers (formerly of UAW Local 2865) and academic researchers and postdoctoral workers (formerly of UAW Local 5810) into UAW Local 4811.[2] UAW Local 5810 was chartered in 2008.[3] The stand-alone postdoctoral scholar contract and academic researcher contract negotiated between UC and UAW are notable for being the first of their kind in the United States, respectively.[4]
