A French prosecutor has opened an inquiry into working conditions at Renault after the third suicide since October at one of the carmaker's state-of-the-art plants...Renault said in a statement that "there was no correlation for the time being between work conditions" and the three suicides. "We have impassioned engineers who conceive vehicles and it is very difficult to draw a link between the workload and the Renault contracts for 2009." A Renault spokeswoman said the company deeply regretted the incidents and extended its respect to the families. She said it was looking into how the suicides could have been prevented.
