So while we are using the throw-away line of flight safety; what about the consideration of Occupational Health and Safety of the flying public that had either booked or were depending upon booking flights. What about doing no harm to passengers through grounding every aircraft without reasonable notice. What about the medical personnel that had critical matters to attend to? What about families who were reasonably dependent upon some level of service continuing, any level of service continuing? What about secondary and tertiary effect upon other people, children, businesses? Isn't this all outside of the realm of 'do no harm'? Is this a breach of Occupational Health and Safety legislation that should protect the public that were depending upon a level of service not, NO level of service? What do the miscreants, including their supporters, say about this?
