It is apparent there are not very many (if any) 'real' Ryanair pilots discussing the demerits of working for said company which infers the vast majority are indeed satisfied in their work.
It infers nothing of the sort. Given the sticky at the top of the board states categorically that the site owners will NOT guarantee anonymity there's a very good chance that anyone with anything negative to say about their employer will be extremely careful in how they may go about it, up to and including silence!
What is a "real" Ryanair pilot anyway?
