First of all, as somebody has already pointed out, that is no discrimination, I need German to work in Germany just like you Brits. Time for you to learn a second language, just like everybody else in Europe.
Equal Opportunity in the UK?
easyJet perhaps. Do you really want to talk about Equal Opportunity in BA? Or even CityFlyer? Or Virgin? Equal Opportunity as long as you get a British passport.
Btw, in the ME they just need pilots, like easyJet and Ryanair in Europe. If they put Arabic among the requirements nobody would fly those aircrafts. They are not reasonable, they are forced to do so.
