Neville Somebody:
When off duty you still represent Qantas
How does that work?? Is there any legal grounds for such a claim??
If your Facebook page tells the world you are a Qantas pilot and displays lovely photos of you in the cockpit, etc. etc.
Then you can expect trouble if you post anything derogatory or confidential.
You can also expect trouble if you join Facebook groups like :
"On a scale from Zero to Brendan Favola, how drunk are you?" or
"Society for the protection of Swedish lingerie models".
Of course if you can't be identified as an employee of Qantas, that's is, I think , a different matter, but why you would be telling an employer to their face that they are not your ideal is anyones guess.
