Does an employee in Texas have any rights if another employee is trying to get them fired?

Question

I work in a dental office in Texas , the doctor does not own the practice, she is an employee just like the rest of us. She has a strong dislike for one of the assistants because this person will not kiss her ***. She has made bogus complaints about her and everyone in the office knows it is just out of spite. This assistant has done absolutely nothing wrong and even the office manager is appalled at the lengths, this doctor is going to in order to have this employee fired. The doctor went over the office manager's head and complained to the suits and the employee was put on 30 day's probation, she was given a substantial raise two days earlier for her performance. How can my coworker protect herself and what recourse does she have, we are all witnesses to this atrocity.

Answer 1

Dental assistants are in high demand, you are working for a self loathing Dentist, find one who OWNS their practice, or if you live near a millitary base, try there.
