I doubt if any aviation company in recent history has seen a more united workforce taking it to the CIA!
Symptomatic of the industry wide culture of treating staff like easily replaceable consumables and of management who, despite knowing exactly what immense value their staff bring to the organization, fail to acknowledge it. A culture driven by fear and the illusion of good, healthy HR practices. Why CASA isn't showing an interest in this is sinister at best. Any airline who purports to maintaining a safety first culture is perhaps dabbling in deception?
