I am working in a hostile environment due to retaliation for not complying to unethical requests from administrator and association with former admin.

In Tennessee, an unlawful hostile environment is one that is based on protected characteristics such as race, sex, religion disability, etc. If the hostile environment is not based on a protected characteristic, then it is simply not unlawu.  Retaliation is unlawful in Tennessee if the retaliation is based on the employee engaging in a "protected activity."  In general, refusal comply with an unethical request is not unlawful.  However, if could be unlawful if it was a request that you violate the law.
