WORKERS at Grinaker LTA, a company contracted by Konkola Copper Mines (KCM), in Chililabombwe have vowed not to resume work until they are paid completion bonus in full.

The workers have refused the 50 per cent bonus demanding to be paid in full and gratuity as their project contract ends this month.

More than 600 workers have been protesting for a week as the Mineworkers Union of Zambia (MUZ) and management failed to persuade them to return to work.

The workers were demanding bonus for sinking shaft four at KCM's Konkola Deep Mining Project.

MUZ deputy general secretary Leonard Phiri said in an interview that the workers had vowed not to resume work until management meets their demands.

"Grinaker LTA has proposed to pay the workers 50 per cent of the completion bonus for sinking the Konkola Deep Mining Project shaft but they have refused demanding to be paid in full," Mr Phiri said.

He said KCM and Grinaker LTA management had been meeting to find a solution and would later meet with MUZ officials.

"We are expected to meet the two managements so that they can explain their position which we shall later relay to the workers. We cannot have a strike indefinitely, it's unfortunate," he said.

The workers initially demanded that the KDMP shaft should stop operating until management settles their dues.
