No, not rich, just feeling aggrieved.
I will look into a return grievance, as I think it probably fits my mindset at the moment. It's just someone who obviously doesn't like me, trying to get me into trouble for some reason. I don't have a great deal to do with the accuser - they work in a different department - so I can't see how I've upset them so, but I think that their behaviour should be marked as unacceptable.
Thanks for your comments, guys.
