MGCU meaning in Governmental ?

The UHM Voice of the Workers is a national trade union center in Malta. It was founded on 29 September 1966, under the name Malta Government Clerical Union (MGCU), and changed its name in 1978 to UHM. The union has members in both the private and public sectors, and emphasizes its political independence. This derives from the polarisation of the political set-up that affects trade unionism in Malta. Amongst the founder members of the Malta Workers Union (UHM), Salvino Spiteri and Maurice Agius respectively were the Union's first President and Secretary General.

The UHM is affiliated with the Confederation of Malta Trade Unions (CMTU), which is in turn affiliated to the International Trade Union Confederation. It represents Maltese workers in various fora including Malta Council of Economic and Social Development (MCESD) and Malta European Steering and Action Committee (MEUSAC).
