Well if I'm not mistaken, 50 years ago the companies paid for all your training. From ppl to cpl and type.
I can sit still, and say "I'm not gonna pay for ****", and then 10 years down the line, I still don't have a job, while thousands of other people, who would have less qualms about it, would be flying.
It is still only training. And yes, in better times, airlines usually pay for it, but outside of the USA, this is becoming more and more a trend.
I draw the line at paying to work, your definition of p2f seems a bit more encompassing.
