Well I don't think anyone actually thinks you might really lower your conditions (at airlines where hosty pay is ridiculously high, I know this isn't the case at all airlines). You've got it, you might as well hang onto it. And why not?
But in all honesty, how about YOU answer THIS question:
Taking into account qualifications, training and the ease of replacement of crew, do you really think the job demands the high salary?
Or look at it this way... if you were an impartial arbitrator in charge of dictating salary levels for a new airline, could you honestly look the staff in the eye and tell them you were going to pay the hosties more than the engineers?
Be honest.
If yes, I'd be interested to see the "justification" without resorting to slanging, threats of banning, coffee-tampering, etc.
