Unity Mine, Cwmgwrach, workers in further wait over job cuts Workers at Wales' largest drift mine face a further wait to learn how many jobs will be lost in cutbacks. Management at the Unity mine near Neath met officials from the National Union of Mineworkers on Monday amid fears that over half of the 200 workforce could be cut. An announcement was expected on Tuesday but the deadline passed with no details being released. Another meeting is to be held on Thursday. Wayne Thomas, general secretary of the National Union of Miners in south Wales, told reporter Gilbert John there had been no discussions about the mine closing.
