Having previously worked in a company requiring taxi duties, I strongly wish this doesn't get implemented here. We were paid 15 minutes per taxi duty. Of course in the real word it took 45 or more. Pay is not the issue I have, though. It is the complete lack of support and communication that is required to make this go smoothly. In my experience there were rarely marshallers and wing walkers waiting for you. After the taxi operation, you could wait forever on a crew bus. Worst of all is that you will probably miss your commuting flight after arriving in Hong Kong. As the whole process takes an hour at best.
So it's kinda like the freighter operation.... you on your own.
Next it will be sign on for taxi duties when its quiet.. i.e. back of the clock, then no transport home or taxi allowance!
