Striking workers at the South African mine where police shot dead 34 miners…face a deadline to go back to work or face dismissal…Lonmin said 3,000 workers were striking illegally and must report to work on Monday. The company delayed the deadline from Friday in light of the killings at the Marikana platinum mine…Some miners said the new ultimatum was an insult to their dead colleagues…The workers are those doing maintenance work to ensure areas are safe for work to resume, Lonmin spokeswoman Sue Vey [said]…About 3,000 rock-drill operators (RDOs) at the mine walked out…in support of demands for higher pay. The strike was declared illegal by owner Lonmin…"The final ultimatum provides RDOs with a last opportunity to return to work or face possible dismissal," Lonmin said…"The safety and security of our employees is paramount and nobody will be asked to report for duty if the police consider them in danger of reprisals," chief financial officer Simon Scott said.
