Because type rating an employee should be part of the operating cost of the Company . It is due to your and your ilk why when you do finally break through the glass ceiling, all you find is splinters instead of crystal !! But you can't wait , so accept the crap that comes with it .
Pay for the rating , pay them for 500 hours in the right seat .Pay them for your upgrade . Hell , fly for free ! As long as you get to fly jets ...right ?
