I don't quite understand why politicians are so happy to turn a blind eye to these kind of practices.
I know of a number of politicians who are completely uninterested in their constituent's situation within the industry. Taking action and forcing change is a big challenge, but they were not even entertaining sympathy for the pilots in question.
It probably doesn't help that RYR is so actively anti-union.
Perhaps a Europe-wide multi-airline strike at all those airlines where there are contract/self-employed/non-airline-employee pilots would create enough attention for the issue to be properly looked at.
