I cant believe what Im hearing here !!
You must know whether you are self employed or not? Who paid NI contributions, who paid your tax etc.? Contract at all?
4 years ago I was offered a position on a self employed basis and when I pointed out that in that case I would consiously make myself available to work for other companies aswell, they decided to offer me a position as an employee!!
There should be no grey area here.
in my case it was justifiable revenge.
Ahhh, thats more like it - Revenge!!
