Spain, like Greece, Portugal, Ireland etc is bust. As they've signed up to the euro
they can't devalue their currency, so instead have to have 'internal consolidation' as the economists call it, ie pay reductions.
No choice - they want a german currency they must show german productivity, or be ejected.
(Not particularly airline staff - all employees in the whole country. 'They are all in this together'.)
Tough on those who work hard and honestly - if they don't like the consequences, they should attack the eurocrats - the real villains!
