New York. My employer knew I was intending to attend graduate school. I gave notice that I would resign in August--a written resignation that my supervisor accepted in the presence of myself and the HR manager. Two days later, my supervisor tried to force me to sign a form saying I had resigned as of that day. I refused to sign it. She said I had still resigned as of that moment. I told her no, she was terminating me. She said, no, I had just resigned. The next day, I showed up for work, and security escorted me off the grounds. Now my employer has denied me unemployment because they insist I resigned. Can I sue them for the money and benefits I would have had had they allowed me to resign on the date that they originally accepted?
