The School of Labor and Employment Relations (LER) is a graduate school at the University of Illinois at Urbana–Champaign. Founded in 1946, the school is the second oldest labor and industrial relations school in the nation. Students at Illinois can earn a Master of Human Resources and Industrial Relations (terminal professional degree) or a PhD in Industrial Relations (which is typically accompanied by an M.S. degree during the process of earning the doctorate). The school focuses on the MHRIR program. Until August 2008, LER was known as the Institute of Labor and Industrial Relations. In spring, 2015, the master's program expanded to accommodate an online program targeted to working professionals.

"Although there is no formal ranking process for HR/IR programs, employers and students acknowledge that the University of Illinois is one of the top three programs" according to the School of Labor and Employment Relations website.
