S.Africa miners to begin Xstrata strike Sunday: union

JOHANNESBURG (Reuters) - South African miners will go on strike at Xstrata Plc <XTA.L> later on Sunday over an employee share ownership program, a union spokesman said.

"It begins at 1800 (British time) this evening," Lesiba Seshoka, a spokesman for the National Union of Mineworkers, said in a text message to Reuters.

The strike will affect all of the diversified miner's South African operations, Seshoka said. The Anglo-Swiss mining firm has both coal and alloy operations in South Africa.

More workers are likely to walk off the job at the start of Monday's morning shift.

No one was immediately available for comment at Xstrata.

The union wants employees to be compensated equally under the share ownership program, regardless of rank, while the company's plan compensates employees based on their level.

Companies with operations in South Africa set up employee share programs in a bid to increase worker ownership, and particularly black ownership.

South Africa's black economic empowerment drive is aimed at rectifying the ownership and income disparities of white apartheid rule.
