I did tell her about that but she gave me the "attitude" and said "I don't care". Very disrespectful. I felt oppressed by her because of my deafness. And she told me to prove that it's illegal for her to do that.
That's the reason why I am here to find out if we have a law like that.
However, from now on I will use a seperate paper for my writing only, not on a supervisor's paper and make sure that he/she doesn't touch my note while reading it. I have had enough.
