No AB. I honestly don't understand your post. That may be me or it may be the way it is written but it seems to have no bearing on who you are referring to when you say
Will someone who has excused this deeply offensive remark
I just asked who had done that - nothing to do with earnings on a 40 hour week which does seem to be a reference to another thread; something GNHQ are getting fairly heated about elsewhere. Why bring that up? It is just confusing. Simple question. Who has, as you call it, 'excused' what?
Presumably, by "deeply offensive remark" you actually mean this simple, well known and often used cliché used in what you consider to be a deeply offensive way. Who did that? The remark, in and of itself, is not offensive in the least. As I have said, it is commonly used when entering a new job and I would certainly be happy for anyone who chooses to, to use it there. I imagine most people would be. That is unless half a dozen people are going to complain about it's use within a job hierarchy.
A cliché is a cliché, useful in some circumstances. Any remark can be used unpleasantly. It is its use that you should then condemn not this useful although limited cliché. To me, this all seems be a fuss over nothing unless you can point us to the person using it unpleasantly. Then we can tell you what we think of that usage.
