Miakk whats you situation exactly? I've been there, done this, and have the t-shirt thankfully.UB have referred to it by that name several times in the course of recent phone conversations - I never heard the term until a couple of weeks ago, but I see it has been mentioned by other posters on the first page of this discussion.
I have the document here in front of me, it is a 2 page document that I signed in addition to the 1 page "Letter of Authority/Acknowledgement" . There is no title at all on it.
The greatest frustration is that I was advised that it was what was required to get my tracker back at the end of fixed term. But now, because of the wording in it, it's the very document that has been quoted to justify not doing so.
