For such things, I would advise that you consult a lawyer !!
As an aside, California (assuming based on your other topic) is probably the best place to have a legal fight -- if you have to have one, that is... That state seems to have the laws that mostly favor the worker over the company.
"Employment bond" is not really a term we use in the US, but as I understand it the term means "employment contract." The concept of employment contracts on principle are certainly legal, but individual contracts and or clauses may or may not be. It will vary by state and as Henry said you need to consult a lawyer.
