By some we are of course talking less than 1% of the coal miner population with enough fundamentals to even have a chance at a quick re-training (a year or two), and the right desirers, personality, and intelligence.
And lets remember, these people ?picked? or at least have been doing for decades a physical trade. Going in and saying to them they all need to become intellectual desk jockeys not only won't work but is just cruel. If you are going to offer opportunities to coal miners, offer them trades retraining.
Governments and corporations might like to think of people as interchangeable cogs, but that is not the reality.
