I would certainly hope that no one would volunteer to fly trips that were supposed to be flown by pilots on strike.
That would be performing struck work and whoever does so would be a scab in any book.
But it's not that simple, is it?
I'm on SBY over the Christmas period, I don't really hold Christmas as that important to me. However, I know that a lot of my colleagues do, they have children and families.
So would I volunteer knowing that I could potentially save someone from missing their Christmas? Of course I would.
