Going back to ACMS's point,
you're absolutely correct - these economic principles apply to every industry at all levels - toilet cleaners to CEO.
Option A - you stay in your current position until your company realises that you really are Mr/Mrs Wonderful, or you have a reasonable gripe (currency exchange is a fact of life people!) and gives you a payrise.
Option B - you go and work for somebody else who pays more or has a more pleasing environment, coducive to your delicate nature.
Unless you live/work in a country where the union is taken more seriously like France, and most of the time the unions are demanding for something that the employer can be persuaded to agree is reasonable. Sadly, Hong Kong/Swire doesn't appear to run by those rules. Just look around at the caring-sharing society you are living in. My 2 penneth, take a reaslitic look around you.
