Thanks for responding so soon.
I wrote that I'd like to give my notice that I no longer wish to work for the company on a work PC, printed it and gave it to him. He read it, asked why I'd like to leave. I explained it was for financial reasons and he said fine, and asked me to leave immediately (I work in sales where I believe this is common practice)
he was sitting with the Ops Director and I was alone so I have no witness so I now don't know to to prove he breached the contracted by not paying my months notice.
