Sane people: Can you give me some much needed advice about my work situation?

Ok, this is going to be a little bit long, and vague so to protect people and their interests…

Today I was at work when my boss came up to me and told me he wants me to give him money tomorrow, the money I collect for the business every day in “semi-illegal/unofficial” commissions.

Me and my boss have a terrible relationship, because he is pissed off that I’m making more money for my self than he expected I would, because of the few little tricks he told me about so I could earn extra cash.

My boss can’t fire me (if he is rational) because I have big secrets over him that would land him in “legal trouble” for a long time.

It is the 31’st, I have a feeling that if I give him the money tomorrow, he will fire me, he has become paranoid and greedy.

The way I see it I have 2 options, I can give him money tomorrow and cross my fingers that he does not try to fire me, or… I can tell him he is not having the money until the end of the year when I get my last paycheck. Call it an insurance deposit if you will, there is no proof the money actually exists, so if he tries to fire me, I keep it.

I have options regarding what I can say and do tomorrow, and depending how he reacts, I have more options regarding what I do.

After thinking about it carefully, I think the most logical thing to do would be to tell him im not giving him a penny until my last paycheck is safe in my hands, it is the option that best protects my interests I think. The problem is this will no doubt lead to an argument, where I would need to then start making threats about “telling on him” to keep my job.

It does not really matter what happens tomorrow, I have already made my money, we are only talking about 2 more paychecks, then the business closes for the year, and regardless of whatever happens, I won’t be there next year anyway.

I’m not too sure I am making the right decision or even thinking about it all that rationally, it is just 2 paychecks, but they are big ones. I’m not sure if greed could be getting at me, or if I’m just angry that someone so insignificant has a say in my life, or both.

I know the details are very vague, and “the rules” are different where most of you live, but I could still use some advice.

Should I give my boss the money and just cross my fingers he does not try anything stupid?

Should I push on him and tell him he cant have it until my pay is safe, and follow that up with more severe “threats” if he gets angry?

Should I carry out my threats (of reporting him) if he does fire me, for revenge and so on?

Thanks.
