Workers of Anglogold Ashanti in Obuasi have served notice that they will embark on a strike action on Monday if management fails to meet their demand for salary increases by Friday. Staff of the mining company are demanding a 15.5 per cent pay rise but management said it is willing to offer 9.5 per cent. The issue of salary disparity in the mining industry was the main agenda for the quadrennial delegates' congress of the Ghana mineworkers union, which ended in Accra on Wednesday. The union is pointing accusing fingers at management, particularly those with expatriate heads as the ones perpetuating the imbalance. The General Secretary of the Union and staff of Anglogold Ashanti, Mr Prince William Ankrah said expatriate management pay themselves huge salaries which are not commensurate to that of the Ghanaian mine worker.
