Thanks for taking the time to explain that to me Gort, I appreciate it. I also appreciate the clarity. I have to admit to being confused about how it works in the US but I did remember that labor/labour contracts have a bit to do with it.

No-one has the perfect scheme and in truth no one scheme will work for every country/culture but it's good to compare and perhaps learn.
