What you have here, in any state, is a dumb butt employer. Which is not terribly uncommon. What you also seem to have is the idea that "may have been fired for misconduct" is a bad thing in regard to unemployment insurance. Believe me, it ISN'T.
If you quit a job, in any state, since we don't know yours, we are speaking very generally here, some states are more or less "claimant friendly" or "employer friendly," but if you voluntarily quit your job, the burden of proof that you had a valid work related reason to quit the job is up to you. You will have to show that you had exhausted all reasonable alternatives to quitting before you quit, in other words, that you tried very hard to work the situation out and that your employer was not reasonable and was not open to working with you to keep you from quitting the job.
If you are fired from a job, the employer has the burden of proof that they had a valid MISCONDUCT reason to terminate you from your job. In other words, that they had warned you, had given you a chance to change the behavior they didn't like, and that you after being fully aware you were doing something displeasing to them, still elected not to change your behavior and keep your job. It needs to be shown with documented warnings and clear cut information provided to you by the employer regarding what you were doing that might get you fired. Else, it needs to be something that is called "gross misconduct." And that means doing something so bad that any reasonable person would've known that it was wrong for you to do it, even one time, without being warned about it. For example, punching your boss in the face, stealing from them, setting the building on fire, etc.
What your dumb boss did was give in to his sense of power and delight at being able, as the business owner, to say, "F___ you! You're a nobody! I'll do it my way! You hit the road!" While this is not illegal in any state but one, and even in that one is only slightly less legal, it is not a good way to terminate someone's employment if you do not want to have to pay unemployment insurance taxes at a much higher rate than before because this person has been approved to draw benefits.
However, I sincerely hope that you have, in any and all conversations with the unemployment office, stressed that you DID NOT quit your job, that you were told to leave, very forcibly, by your cursing swearing employer. And then you obliged him by leaving. In the meantime, your employer, as soon as he received the notice that you had filed your claim for benefits, has probably figured out that he screwed up. And he will probably change his story to how you voluntarily quit and walked off the job. He will and the other worker who want to stay on his good side will probably all swear that you said, "I quit!"
The thing is, in unemployment insurance, your word and what they say is weighed, and the decision is made based on which of the two parties are most believable of what very well be two liars both telling different stories. They don't care, they'll go with the one who is most believable.
You filed for unemployment benefits, you probably had monetary eligibility for them, and thus a decision is in the process. Hopefully, you are making the weekly or bi-weekly certifications for weeks that pass, even though you are not being paid right now. If you are approved for benefits, you will be back paid to the time you filed a claim( except for the first week, which is a waiting week, if you happen to be in a state with a waiting week) but ONLY if you have made the certifications for each week. Read the instructions carefully on how to do this, and make sure you're doing it.
When you talk to the unemployment office, do not come down over and over about how you weren't getting paid and how you used to be paid and you used to be allowed to make some commission at xxx number of dollars a so much, and yada yada.... The thing is, that's not the issue. The issue is that you were having a disagreement with your employer about how you were being paid, and how much you were being paid. You had discussed it with them, and you were doing that at the time of your termination. What they are really going to come down on is exactly what happened at the time of your termination. What were you told? What did you say or do? Did you say you quit? Did you threaten to quit? Don't even go there. You didn't intend to quit the job, you intended to try to fix the pay problem.
And don't try to even sort of hint you didn't get fired for misconduct. Embrace that! IT IS NOT BETTER TO QUIT THAN BE FIRED! That is a view pushed by employers who don't want to pay high unemployment taxes. Legally the employer can fire you for any reason under the sun. But if they cannot show they had that valid misconduct reason to fire you, then they probably will lose the case and you will be approved to receive benefits from their tax account while looking for another job.
Keep your story consistent, do not try to argue with the employer, no matter what sort of silly thing or wrong things they come up and accuse you off. They may say you were a lousy employee, that you three years ago, got written up for breaking a pipe wrench, or that your performance was poor overall, whatever they can throw in that they can think of that might show they had a valid misconduct reason to fire you. Do not try to rebut their arguments or disprove everything they say. Just tell the truth, "I never thought my job was in jeopardy. I did not quit my job." And your chances of being approved for benefits are fairly good, in my OPINION of course.
