Thank you for your question. I look forward to working with you to provide you the information you are seeking for educational purposes only.
Is any of this being done to you based only on your age/race/sex/disability/national origin, because legally as an at will
employee that is the only protection you have. Under the Texas law, an employee is protected from harassment or retaliation
only if it is based solely on their age/race/sex/disability/national origin or for reporting discrimination
based on one of those grounds. See: Oncale v. Sundowner Offshore Services, 523 U.S. 75 (1998).
If your grievances about your employer are not based only on one of those reasons above, legally there are no employer protections for the employer and as an at will employee they can terminate, hire, fire, promote or demote an employee for no reason or any reason not based on one of those illegally discriminatory reasons.
If they are falsely accusing you of discriminatory conduct and you prove the allegations false, then you can sue the employer and the parties who made the false allegations against you personally for defamation and you can seek money damages from them for any damage you suffered as a direct result of their known false allegations against you.
