I was released from my hours at a local hospital through a staffing agency from what they are term ing as a hipaa violation, long story.

Unless you have a written employment contract, you can be let go for no reason at all, under the legal rule called "at will" employment.  There are a very small number of exceptions to that, illegal reasons for firing such as discrimination, or retaliation for exercising your right to file a workers compensation or wage and hour claim, to name a few.  So even if what you did really wasn't a HIPAA violation, or it wasn't your fault, that doesn't mean you can sue to get your job back.

However, sometimes a legal reason for firing is used to cover up an illegal reason, and if you think that might be the case, from the long story that you haven't talked about in your question, you should talk to a labor and employment lawyer in your area as soon as possible.  One place to find qualified attorneys is our website, http://attorneypages.com
