What she did was unethical and i think you would have a very hard time suing her, she would probably make things worse for you. It's a tough one because she was wrong how she handled the driving by her house on a public street, that to me can be worked out, yet she choose to terminate you. I don't think it would turn out good for you if you went ahead to sue. Maybe talk it over with your t if you feel comfortable doing so. Hugs
