Teresa - not sure which "Engineers Union" you are referring to. From your example, you appear to refer to LAMEs, however I believe their EBA bargaining is yet to commence. If you are referring to the Professional Engs, I have not seen any of their publicity referring directly/specifically to any of the recent "events".
Nevertheless, do not believe that QF, specifically QF mgmt, is innocent and helpless to prevent the brand damage you refer to. Their "style" of EBA "negotiation" with almost all unions typically leaves little other ultimate recourse for the union other than to turn to the media. Add some lingering and widespread "disengagement" issues throughout the rest of the staff, and you have the recipe for the
PR debacle we are currently witnessing.
