Pretoria - Chief executives of Implats, Amplats and Lonmin as well as Amcu president Joseph Mthunjwa did not attend talks on Monday morning aimed at resolving a strike in the platinum sector.
The mediation process, which began in Johannesburg on Friday, resumed in Pretoria on Monday.
Association of Mineworkers and Construction Union (Amcu) general secretary Jeffrey Mphahlele said the union was not consulted about the media taking photographs during a photo opportunity.
Representatives of the platinum producers sat on one side of the room and Amcu representatives on the other. Mediators from the Commission for Conciliation, Mediation and Arbitration (CCMA) sat at a table facing the opposing sides.
Amcu members stood up and sang loudly, while a CCMA official ushered the media out of the negotiation room.
Amcu workers went on strike at Impala Platinum, Lonmin, and Anglo American Platinum mines on Thursday.
The union is demanding R12,500 per month for entry-level workers, but the platinum companies have said this was not affordable.
The CCMA is acting as a mediator in the negotiations. - Sapa
