Cartexhange and Paxing,
Pull your head out of the airline environment for 5 min and broaden your understanding of the Australian Unions and you will QUICKLY discover that union fees based on pay scales are a common scheme within Australian Unions....
And furthermore, if you raise the argument of paying less for fees = less representation, then i will be just as childish as you and say if QCCA are paid less than QLH then QCCA should work less than QLH...
