Hi, need some advice desperately! As I was leaving work on Thursday my boss came into the office and said he was sorry but going to make my day worse as he "had to give me (one month) notice as things weren't working out". Shocked doesn't explain how I felt. He continued by telling me that he felt bad because he really liked me and thought I was really intelligent. He also said that I wasn't like his original EA- he's let go a few other EA's in between her and me. He said a client complained about me- when I asked who, the person he said is someone I have very little contact with other than confirming meetings? So it made no sense. He then said he'd provide me with a reference and he'd like me to leave on good terms. I have never received any warnings written or verbal. Is this right that he can just get rid of me for no specific reason and without warnings?
