Is it possible to prove that my dismissal was forced?

I worked at a small private enterprise for 5.5 years. All these years, I received my salary with delays. Initially, it was by 5-10 days, and in recent years, by a month or more. I repeatedly spoke with the owner, and twice wrote him letters. Bank statements are available. As a result, I resigned. Is it possible to prove that my resignation was forced? Is it possible to receive compensation?
