Lonmin chief executive Ben Magara.

Johannesburg - The chief executive of platinum producer Lonmin has told staff to take voluntary leave because a wage strike at its South African operations by the Association of Mineworkers and Construction Union (AMCU) looks set to continue.

“Given the reality of a prolonged strike and AMCU's unrealistic demands, we have to make tough decisions to preserve and protect the business by reducing costs and conserving cash,” Ben Magara said in a March 25 memo seen by Reuters. - Reuters
