Michigan unemployment appellant. Can I subpoena witnesses from the job at the work address if I know they are still employed there?

I was terminated for misconduct (violent slur) but I had been threatened multiple times, reported it with nothing done. I know people that are enemies of mine are sources at every job I go to to sexually harass me and also aid in workplace harassment. They neglected my contract for benefits. They didn’t document my threats, someone put a noose in my locker etc. just a bunch of wrongs on me then I was the fall guy. If they wanted to fire me I understand I made a mistake. But I don’t think it’s two wrongs don’t make a right, I think it’s a ton of wrongs on them to my one retaliation. So I didn’t even apply for unemployment up front, but I couldn’t get a job and needed unemployment assistance. I don’t get how this is being denied. The group of guys abusing my life at my jobs also stalk and blackmail me outside of work to keep me from getting jobs. They also spread and exaggerate that I was fired and told people why. Also not legal.
