If you want a forklift driver and you hire somebody that doesn't know how to then you're on the hook to train them. If you're worried they'll just turn around and quit either don't hire somebody without the training. If said forklift driver wants to go back to college and say learn electrical engineering I think the employeer could add stipulations on that.

Charging them for training you didn't actually provide is a bit ridiculous. Too bad the case only got dismissed and nothing punitive.
