> My previous boss had a personal vendetta against me and made my time working for her really difficult. Eventually, I was moved out from under her to a different team within the same department. So when asked, I simply told the HR person that my previous boss and I didn’t have a good relationship, and that I could not rely on her for a reference. IMO, I wouldn't consider this person "my previous boss" and just provide a reference from a previous employer. I wonder how long they worked together? Was it a few weeks, months, or years?
