Whilst I support the sentiment of not turning up to the meeting, and I definitely wont be going, that will not achieve anything. I went to my first meeting last year (having been here quite some time) and noted that the audience is made up mostly of sycophants who get a huge amount of satisfaction by being told they are part of the greatest airline on earth, and spend most of the meeting applauding themselves. No one there is likely to, or will probably be allowed to ask any hard questions. And if not one pilot turned up, no one would even notice. The usual suspects from flight opmanagement will be there to high five each other and tell everyone how good they have done over the last year.
If you are unhappy the only real option is to leave. Not that it will have any impact on our management, nor will it change anything for those who stay, but at least you may be a bit happier.
