Just for clarification, Right to Work is the right to work without being forced to pay union dues. In other words, you can work in a company that is unionized, but do not have to pay union dues or join the union. I think what you meant to say is that OK is an "at will" state. This means that you can be fired for good cause, bad cause or no cause, just not an illegal cause (Title VII, ADA, etc. violations).
