LUSAKA, Jan. 4 (Xinhua) -- Unionized workers at Konkola Copper Mines, the Zambian unit of London-listed Vedanta Resources Plc, on Wednesday refused to work in protest over salary disputes with management, a move that disrupted operations, several local media outlets reported.
Over 700 miners from the firm's Konkola Business Unit in Chililabombwe town on the Copperbelt Province, refused to work as they demanded for salary adjustments as well as improved conditions of service.
Some workers told local media that their salaries have not been adjusted in the last four years while the cost of living has gone up.
They also complained of lack of proper treatment and medicine at the firm's hospital as well an increase in fees at a school run by the firm while their salaries have remained static.
The workers said they will not work until management gives them an assurance on improving their working conditions.
Union leaders were locked up in a meeting with management.
The firm has been facing challenges in recent weeks. Last month, the firm's contractors and suppliers protested over delayed payments for services and goods supplied.
On the other hand, a court in London recently ordered the firm to pay the Zambian government 100 million U.S. dollars for a claim related to a 2013 copper price participation agreement.
The government has expressed concern over the situation at the mining firms and has since urged the management to give an assurance of the firm's ability to maintain operations.
