Tanzania Teachers’ Union is a trade union of teachers in Tanzania mainland. The union was registered in 1993 under the Trade Union Ordinance, Cap. 381of 1956 and given its registration number TU. 002. In 1998 the Parliament of the United Republic of Tanzania passed a new trade union act (Trade Union Act No. 10) which led to re-registration of trade unions in the country. Under this new Act, TTU was re-registered under the Trade Union Act No. 10 and was given a new registration number TU.004.
TTU stands for both teachers' professional responsibilities and welfare of teachers.
