High Quality Content by WIKIPEDIA articles! Voice (formerly The Professional Association of Teachers) is an independent UK Trade Union, founded in 1970 by two teachers who gathered together a group of like-minded professional teachers who were prepared to commit themselves to the principle of not striking. The union represents teachers, lecturers and other education workers in all areas of British education. The charity PAT (Education and Learning) was launched by the Professional Association of Teachers in 1999. In February 2008, Professional Association of Teachers became Voice: the union for education professionals. Then in June 2008, the charity PAT (Education and Learning) changed its name to Voice (Supporting Education and Learning).
