You are going into Willie O'Dea territory there. Just because Ryanair outsource some of their jobs to agencies, it doesn't mean the employees are not covered by employee legislation. To imply that Ryanair are operating some sort of sweat shop is ridiculous in the extreme.
So what? As long as they operate under employment law, I don't see the problem. I also can't remember the last time Ryanair went on strike, which isn't bad considering how ruthless & profit centered they are perceived to be.
Or possibly like this:
MC: Good morning, Christoph, Mary Coughlan here. What will it take for ye vacate Hangar Six?
CM: Sechs?
MC: Ah come on now Christoph, I'm very flattered but it's jobs we want, not knobs
CM: Knobs? I'm sorry. My English is not very good. We want Sechs.
MC: Christoph please. I never had this problem when Willie (Walsh) was in charge. I miss Willie.
CM: I'll be over on the next flight!
