CAT 1 reversion,
I don't know if your post was referred to me. What I mean by my previous post is that you British might not be on the no.1 list for hiring in say Finland because you don't speak Finnish. I agree all ATC communication and checklists etc. should be made in English which I'm sure happens all over EU (except certain French, Itallian & Spanish carriers

) but I do think it's okay for the airline to require you speak their national language if your employed there.
Look at KLM & Transavia they require too that you have to learn Dutch if you get a job with them.
I guess us foreigners are just really lucky in having to learn different languages early from school as we don't have an international language as our mother tongue
