Your rights as an employee without a written contract or union affiliation are very limited. You could tell you employer in writing and (politely) ask them to reconsider. There have no duty to move within 3 days time or any other delay, and you could, in an at will state like California, have been fired for no reason.
The above is general legal and business analysis. It is not "legal advice" but analysis, and different lawyers may analyse this matter differently, especially if there are additional facts not reflected in the question. I am not your attorney until retained by a written retainer agreement signed by both of us. I am only licensed in California.

California is an at-will state, meaning that your company can fire you for almost any reason. Unless you have a contract saying otherwise, you are most likely an at-will employee. Once your company decides to fire you, there isn't much you can do, especially if you have already tried explaining and they refuse to listen.

Unfortunately, employees and job applicants have very few employment rights, and employers have a lot of leeway in how they choose to run their businesses. In general, an employer can be unfair, obnoxious or bad at management. And an employer can make decisions based on faulty or inaccurate information. It’s not a level playing field. An employer hires employees to provide work for its benefit, not for the benefit of the employees. Don't expect the employer to take care of its employees; it doesn’t have to and it rarely does.
There are some limitations on what an employer can do, mostly in the areas of public policy (such as discrimination law or whistle blowing), contract law, union-employer labor relations, and constitutional due process for government employees. Please see my guide to at-will employment in California which should help you understand employment rights: http://www.avvo.com/legal-guides/ugc/an-overview-of-at-will-employment-all-states. After you take a look at the guide, you may be able to identify actions or behavior that fits one of the categories that allows for legal action. If so, an experienced plaintiffs employment attorney may be helpful.
Now with a better understanding of your limited legal rights, think about a strategic solution instead. Consider tackling this directly, professionally and respectfully. Understand the company may have misunderstood events or perhaps felt there was something wrong with your work but never told you. Ask to speak with HR. Ask if you’ve done something indicating you are a poor worker or if the employer thinks you were responsible for something that happened. Maybe something was misinterpreted, though probably not. But if so, you can explain your side. More likely you will never know what is really going on. However, a mature conversation may change the way the employer treats you and may cause a change in the decision.
Whatever you do, don't challenge the employer’s authority. Indicate you want to continue your working relationship and value your job. Explain you care about doing a good job. Mention your good work record if you have one. Explain you would never intentionally do anything against the company's or your boss' interest.
Do not blame anyone else even if you believe someone deserves it; this cannot help you. Only talk about yourself, that you want to do a good job, and you regret the situation. Ask what you can do to improve things for the future. Don't give anyone a reason to get angry.
The company may see you more favorably after this. Even if it doesn’t save your job, it may prevent a fight about unemployment and might get you a good job reference.
I know it's annoying to have to do this when you didn't do anything wrong, but remember, an employer doesn't need a reason to fire you. And as we all know, the current economy is tough and jobs are hard to come by.
Employment rights come from the state and federal legislatures. One of the best things people can do to improve their employment rights is vote for candidates with a good record on pro-employee, anti-corporate legislation. Another way to protect employment rights is to form or affiliate with a union, or participate in a union already in place.
I hope you can resolve your situation and wish you the best.
