I don't think this applies to Emirates alone. It is quite clear the person concerned is out to put them-self in the limelight or gain an advantage in one way or another.
I experienced something similar although not in the aviation industry in fact it cost me my job.
Such things happen in every industry. You always will get one who wants to get the better of you.
Is this due to jealousy, an inferior complex or just plain bad character? It is beyond my comprehension!
