Coal supplies needed by Eskom for elec-tricity generation could come under threat. Solidarity members have instructed the trade union to serve strike notices on coal mines that negotiate under the banner of the Chamber of Mines. This means that workers will officially go on strike from midnight on Sunday at the country's largest coal mines, including Anglo Coal, Xstrata, Optimum Colliery and Exxaro. Solidarity is demanding a 15percent pay increase for its members. -Staff Reporter
