If you can prove what they are doing and why you can file a civil claim against them....
You need to get proof of why you got fired. Did you sign anything? Get a copy of the paperwork you filled out when you ended your employment.
If she is just flat out lieing and you have no proof, then there's nothing you can do, just stop using her as a reference. But if she is saying bad things about you, then you have a case. Employers are not allowed to say anything bad about your performance.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
