‘Disposable tools’: the miners’ union answers De Beers

The National Union of Mineworkers has condemned the two-year Venetia pause that puts 1,134 mine employees and 80 sales staff into consultation, accusing De Beers of presenting a predetermined decision and proposing cuts that start in the executive suite.

§1Not conciliatory.

The response to Venetia arrived within days, and it was not conciliatory. The National Union of Mineworkers, South Africa's largest mining union, has formally condemned De Beers' plan to halt production at the Venetia mine for two years, a move that places 1,214 workers into retrenchment consultation: 1,134 permanent mine employees and a further 80 at De Beers Sightholder Sales South Africa. NUM's diamond-sector chief negotiator, Masibulele Naki, put the union's position in one line: "Workers cannot be treated as disposable tools".

§2The charge is timing.

The union's sharpest charge is about timing, not economics. De Beers, NUM argues, has known about the challenges confronting the diamond market for a long time, and yet presented the pause to the workforce as a sudden necessity, with dismissal notices issued before any meaningful engagement. In the union's telling, the consultation now underway is theater around a decision already taken, and the company's communication before the announcement was close to nonexistent.

NUM is not arguing that the diamond market's troubles are imaginary. Its counterproposal accepts the pressure and redirects it: executive cost reviews before worker retrenchments, retraining programs for underground staff, and spending cuts that do not start at the bottom of the pay scale. The union has pledged to use all available organizational, legal and collective bargaining channels to protect its members, which in South African labor practice can stretch a Section 189A process considerably.

Every diamond-market downturn eventually stops being a price chart and becomes a payroll.

§3An awkward hour to be sold.

The fight lands at an awkward hour for the company. De Beers is being sold; Anglo American has named Gareth Penny's consortium as preferred bidder, Botswana has negotiated its own stake upward, and the Venetia pause is part of the cost discipline that makes the asset presentable. Venetia is South Africa's largest diamond mine and the country's principal remaining stake in an industry it once defined. A two-year pause with 1,214 jobs attached is, for the Limpopo towns around the pit, indistinguishable from a closure with a promise stapled to it.

The Desk’s ViewDiamonds

Every diamond-market downturn eventually stops being a price chart and becomes a payroll. The union's argument that the company saw this coming is hard to dismiss: this page has been charting the rough market's slide for months, and De Beers' own sight cuts told the same story. The question for the new owners is whether Venetia's two years dark end in a restart or a eulogy.

The workers have noticed that nobody will put the restart in writing.
