A "right to work" state is still an "at will" state in that all employment is at will unless you have a written contract guarantying or protecting your job. ("Right to work" means you don't have to join a union or pay union dues to have a job--it does not actually give you a legal right to have a job or avoid termination.) Since for this purpose, if you don't have a written employment contract, you are an employee at will, the employer does not need to "justify" or "verify" the reason for the termination: they can terminate you for any reason at all, at any time, and do not have to provide an explanation. Therefore, you have no right to see the survey.
