I would like to know if I have grounds for a lawsuit against Universal Marble & Granite the company I used to work for? I was fired on 09/19/2012 because my boss Sareb found out I was looking for another job. Is that legal??? Thank you and hope to hear from you soon.

Did you have a contract with your employer which stated the grounds for which you could be fired?  In some cases, such an agreement could be oral, or could be in the form of an employee manual.  However, in most jurisdictions, if you don't have such an agreement you are employed "at will", and can be fired for any reason except those that are prohibited by statute (e.g. discrimination on the basis of race, whistle blowing, etc.)
