The mines WILL put up with it because they have no choice.
Mr Minesite, "We're cancelling your contract because your pilots don't meet our minimum requirements."
Mr GA operator says, " No one can meet your requirements anymore either."
Mr Minesite says, "Sure mate, pilots are a dime a dozen. Everyone knows that..."
Mr NJS/Alliance/Skywest/pick one then says "spend 5 mil to upgrade your strip then we'll do you a great deal on a jet service."
Mr Minesite says,"But we only need to move 15 people 3 times a week...."
Mr Minesite says,"Mr Skippers, forget those requirements. We can't get truck drivers. Can't imagine how hard it is for you to get decent bus/plane drivers."
The industry wide skills shortage means that the minimum requirements for any position whether it be flying or cooking meals is going through the floor. There are many many examples of this.
The aviation industry is no different.
