Be Careful What You ask For
CILOC is good for most of us most of the time. It particularly protects us against facing exhorbitant charges dependent on our posting location. If it was replaced with a local rate then many of us, especially the lower paid, could suffer. (I accept that there would be some winners) And it also pays the local tax overseas IIRC. It certainly did in Germany.
This is a bit like the clamour for PAYD. Now we're getting it and I don't see that many happy faces.
Finally, how many times have adminers been slagged off on this forum? Well we've got our wish; they're going (not all I know) and we have JPA. Hurrah!
