Johannesburg, South Africa — ESI-AFRICA.COM — 30 August 2011 – The National Union of Metalworkers of South Africa (NUMSA) has confirmed that it has refused to sign a wage deal with South African national power utility Eskom Holdings.

Announcing this development here, NUMSA said that a strike by its members was not imminent, but added that “if it comes to the push, we will not hesitate to mobilise our members for an industrial action.” It said Eskom was offering a 7% wage increase while it was demanding 13% across the board.

Eskom, which supplies virtually all of the power to Africa’s largest economy, has also been locked in wage talks with the National Union of Mineworkers.
