Alpha Leader and ironbutt, you guys are amusing. You are playing on semantics. AL has whittled the complexities of this dispute down to whether a person who defies the Ban should be described as a noun, or his actions as a verb. "He is scabbing", "Yes, but he is not a scab".
Go back and read your OWN definition of SCAB, the noun.
However, for your benefit, a person who is scabbing (v.), or who has scabbed(v.), is a SCAB.
Tin Ass, there ARE Ansett scabs from 1989 - you will find their names on a well-known website, or alternatively they are listed in a little black book with a yellow sp(l)ine.
The "Recruitment Ban" was published - full page - in Flight International and numerous daily tabloids.
"Continental and Eastern scabs are now union members" - but do you TRULY believe that their names and actions will EVER be forgotten, by those whom they dis-advantaged? Never!
C'mon IB, I'll bet even YOU can rattle off a couple of dozen of their names pretty effortlessly. Don't ever regret that you did NOT join them.
If either of you would care to name a dictionary that says to qualify as a SCAB, one has to cross a picket line, I'd be happy to hear from you.
