We can't answer this accurately without details about the job. (For example, your prior work, hours, length of employment, etc.) You were wise to keep your question vague on a public board, but it makes it impossible to answer.
You should talk to a local employment attorney. Then you'll have the benefit of confidentiality and advice that is specific to your facts.
If your boss continues to refuse you work, and if that means you don't get paid, you may be able to collect unemployment. But that is VERY dependent on specifics.
Get an attorney, really.
