The Association of University Teachers (AUT) was the trade union and professional association that represented academic (teaching and research) and academic-related (librarians, IT professionals and senior administrators) staff at pre-1992 universities in the United Kingdom. The final general secretary of AUT was Sally Hunt. AUT also had branches in a number of post-1992 universities (the ex-polytechnics and other institutes that have become universities since 1992) and in university colleges, although the main union representing academic staff in these institutes was the National Association of Teachers in Further and Higher Education (NATFHE). On 2 December 2005 the results of a membership ballot on a merger of AUT and NATFHE was announced. The merger was supported by 79.2% of AUT and 95.7% of NATFHE members who voted. The two unions amalgamated on 1 June 2006, and after a transitional year, full operational unity was achieved in June 2007. The new union is called the University and College Union (UCU).
