Has anyone here been fired (from a restaurant) to claim unemployment benefits?

I’m kinda over my job bartending/keys or “manager” at this restaurant. I’ve been there for 5 years and I’ve about had it with the owner and his lack of management. I’ve never gotten fired from a spot so idk what would allow me to collect unemployment. I have a seasonal side business that’s under the books so that’s why I’d like to wait before getting another job.
