The official figures given by QF management is that the shutdown cost $190M plus $62M in legal costs - everyone suspects that these figures understate the costs significantly. As Joyce was given very little of what he asked for by FWA, I can't see him being stupid enough to go down that path again.
Common sense would suggest you are probably right. However Joyce was hailed by the Business Community and the Liberal Party as a hero and it certainly pushed up his social capital within those ranks despite it being an overwhelming loss for Joyce. The narrative was that he had courageously taken on the Unions and won. He also managed to gain the help of the Labor Party in doing so. Whether this perceived victory has embolden him to try it again we are yet to see, however I would agree that the smart money will be on never trying something so stupid ever again. However the real issue for the Pilots (Just like 1989) is that the shutdown was never about money.
