That was quite a mature and well balanced response Cyril. Good on you. To answer your question about A & B scales. A scale basically doesn't exist anymore and refers to the package that guys had almost a decade ago. B scales is what happened when CX management attacked the A scale package and is much reduced. Most guys are on B scales. C scale is basically B scale minus the expat housing allowance. It is what everyone is basically warning you about.
Good luck with whatever you do.
