Hi Broken Arrow,
Sorry to hear of the circumstances you find yourself in.
I'd go visit the local Citizens Advice Bureau, and get advice and help from them. It's all free, which is a good enough excuse. However, you should also contact and make an initial one-hour enquiry with a relevant and reputable solicitors. The first hour is always free, as far as I know, and thereafter they do charge.
However, if you are out-of-work, they should be able to sort your case out for free, via Legal Aid. I should just point out, however, that not all solicitors and lawyers do Legal Aid work. So double-check!
Good Luck, and hope you find a new job soon. Plenty of high-street places are starting to advertise for Christmas work, which may tide-you-over financially for the time being, if you don't want the hassle of looking for something more long-term, until you are either more financially stable, or until matters have been dealt with, over your current (ex) employers!
