Heavy "we know who you are" type threats sound very ominous and much like the rustbucket industries in the 50s and 60s. Look where most of those are now. To strike or not to strike should always be an individual choice. So called majorities can get very ugly- and in these situations are very ugly. We should not be seeing these,- or attempts to suppress views in any way,- amongst professionals, especially when they have plenty of choice of alternative employers if this one really is so dire in the realistic context of the current aviation world. Courage means going somewhere else if not happy, not threatening people who hold different views. Who likes schoolyard bully tactics?
