Leigh Clifford is ex CEO of Rio Tinto, a company I worked for during most of the nineties. Rio Tinto does not take kindly to Prima Donna's, BS artists or fools. Unfortunately a large portion of QF management fit into one or more of these categories, and they tend to stifle those who show real promise as efficient managers.
When it comes to sorting out inefficient mine sites Rio Tinto like to do their culling from the top, and then work their way down to the shop floor. All Prima Donna's, BS artists and fools are systematically extracted and either outright sacked, or moved to positions which would cause lose of face and their resignation.
It is a very messy process with much nashing of teeth, but the outcome (as they say) justifies the means.
If this is the start of a culling op, then GD will be just the start.
