If a company was paying for his training they would have cut him loose and stop throwing away money on him. P2F was notorious for a lot of deadly accidents in the 90s and early 2000s because any one who had the money to throw away could fly those airliners. The P2F companies kept allowing subpar pilots to fly because not only were they not spending money on their salaries but the sub par pilots were actually paying the airline to fly their passengers.
