Every single year we have gone without a payrise we assentially made a concession.
Every time you pay more for a staff ticket - you make a concession.
Every time you miss a family event because nobody in management can be bothered to get us a grown up rostering system - you make a concession.
Every time an FO or Captain gets hired above you and you don't get your bypass - you make a concession.
Need I go on?
Enough has been given.
