Quid pro quo
The language issue should be treated like some international agreements: bilateraly on a quid pro quo basis.
If in Germany they require german proficiency, in Spain we should require spanish proficiency... for german pilots (nothing personal!)
If in Holland they only require english, in Spain we should only require english for dutch pilots.
And so on...
Right now, there are more spanish pilots abroad than the opposite, so let's just keep things they way they are now...
How could we make spanish proficiency mandatory if many spanish people cannot have a career in Barcelona because they can't speak catalonian?? That is nonsense.
Let's focus on uniting and protecting ourselves because the management staff is growing smarter an smarter and we became dumber and dumber each day!
