First a correction "talking about plant operators and there" I meant to say process operators sometimes referred to as fixed plant operators, process technicians, gold room operators or or gold room technicians.
Secondly I have just checked and yes you are right there are aprox that figure as of Jan 2013 employed directly in WA (including contractors) but that doesn't change my statement that 50,000 job losses have not occurred across the industry, as you originally posted. Process operators fall within directly employed and I know of 5 mining companies looking for process operators currently.
Boom / Bust statement of fact that is how the mining industry works it is cyclical in nature, due to commodity prices and commodity demand and economic conditions. While it has shown growth over the long term due to world population growth and hence commodity demand, it still maintains its cyclical nature due to economic cycles.
I have been through other busts and have received redundancies before and have been one of those kept on when cuts where made, I am currently a contractor so when a mine shuts down I will find my next drilling contract or live on my savings (a contractor who doesn't save isn't a contractor). So I'm quite aware and have been through and ridden these down times and anyone who doesn't think they can cope with that should consider an alternate career. The government, companies, recruiters that sought skilled workers did so to fulfil a need, should they have not recruited on the basis one day things would turn around? Ho Hum not my statement but yes I agree. We're all adults make our own choices and decisions in life and bear the consequences.
