I have put "HR Analyst & Virtual Assistant". It is a bit long, but I have a long surname so it looks ok!

I have used this as I wanted to be more descriptive about what it is I actually do. Having said that, as we know, lots of people don't know what a VA does and similarly, there are not too many people who know what an HR Analyst does either! When I run my next batch of cards I am going to use the back of the card to put a description of the work I do.
