I was required by my employer to provide medical documentation regarding my health, which identified I have breast cancer and the possible treatments depending on outcome of surgery. The day it was received, my employer indicated that it was time for my performance review & asked me to resign or he would fire me. He would not give me any specific reasons for this. I was given positive feedback until that day. I had never received any indication that I was not performing job to expectations or that there were any concerns regarding my job performance. (This issue is being handled legally due to his discrimination.) I am now unemployed. In an interview situation for a new job, how do I answer a question regarding why I left my most recent job without disclosing any of this information?
