Then until this ruling is made by the courts BA pilots should not be asking other pilots to take indirect action by refusing to join OS etc. The recruitment ban should be suspended forthwith. I find it very distasteful that some BA pilots have threatened to label others as "scabs" etc when there is doubt over the legality of any action against OS.
The dispute is real enough the legal issue is BA trying to block the BACC's attempt at preventing BA driving a coach and horses through our Ts & Cs in the future. Why not undermine the BACC just like a certain UK airline did to the Australian pilots in their major dispute in the 80s? An airline whose CC was mentioned earlier as a shining example of how industrial relations should be conducted.
