Qantas HR investigated the claims and cleared all of the accused parties of any wrongdoing and has cleared them to return to their duties.
Guaranteed if QF HR could find anything untoward it would have been pursued with great gusto in my opinion.
Some good people have had their reputations dragged through the mud and have been exonerated. Sadly, people allowed that to happen and the chief amongst them has lost any sliver of respect that may have been left.
The person who made the allegations is not back flying.
Draw your own conclusions.
