Underpaidpilot your post made me sad because even though I am cabin crew it has become very apparent lately that, although most crew are amazing, there are a select few who you can not trust. I notice too you are from Oz. (I am too) Not sure what company you are from but I am guessing we are from different companies as mine is a larger one. Crew who back stab pilots/crew do it to get promotions. I hate this, good CRM is really important. I'm really sorry you got one of the bad eggs
(apparently its not just CC I have heard of a FO doing something similar)
