Err A Lurker - think you need to read your ballot script again.
Even the Union states on the ballot paperwork that "you may be in breach of your contract."
I do hope that when encouraging people to vote yes, you know your stuff. If people do get sacked, or do get given a new fleet contract to sign after striking - what compensation will you be able to offer them?
You can keep stating that BA can't do it. Fine. Go ahead - test them and put your own job at risk.
But to encourage other people to do so when you clearly have no idea what could happen next, seems pretty reckless to me.
