One piece of advice, after reading your petition: You should get the facts straight, and point out why the general public need such a law. When it sounds like a frustrated aspiring pilot is venting his anger, that does no good to convince the public or politicians.
Especially this part is just not true, if you look at it from a global perspective:
In the meantime, thousands of qualified and unemployed European professional pilots are unable to find a job partly because, out of corporate greed, those airlines choose to use pilots who pay to work.
The fact is, the total number of pilot jobs is not altered by the existence of P2F. If at all, it will increase the number of jobs because flying becomes cheaper, so more passengers will choose the plane over other means of transport, thus creating more demand for pilots.
Another fact is, you cannot blame the passengers for choosing the lowest airfare, because even if an airline was charging higher prices, that would just increase their profit, they would not give the money to their pilots if they don't have to.
The only way this can be stopped is by labour laws, which are unfortunately not harmonized in the EU, but a matter of each national state. Thus enabling the airlines to do "forum shopping" for the lowest possible standards. The other way is by way of labour relations, i.e. existing pilots of an airline solidarising with their weakest colleagues, and taking action to create collective labour agreements which prohibit P2F.
