The subject of titles for "office professionals" is a perennial one.  I remember being asked about this very thing many years ago. 

There are many titles that one might use within the business environment to describe an office professional and they mean different things in different companies and this is possible because none of them are legally protected titles.  The title, ultimately, doesn't matter.  What is of significance is the way that post (not the post-holder, although there is an element of this) is perceived by the employing company.

I was happy with my last title, Executive Assistant to the CEO.  I'm even more pleased with my current title, Assistant Company Secretary.  I'm pretty fluent in most of my duties; the statutory ones I shall learn, and ICSA training begins a little later this year.  My post is currently ranked just a couple of grades below Director level, although they do earn a fair bit more.  As my nephew would say "What's not to like?"  As long as I measure up, I shall be content.  I have noticed, since I returned from Christmas vacation, that the way people react towards me, with my current job title, is subtly different.
