In Texas, whistleblower claims only apply to governmental entities, including school districts.
If you, in good faith, report a violation of law, to what you believe to be an appropriate law enforcement authority you may be protected from retaliation. In whistleblower claims you must initiate your employer’s grievance procedure first, so you must act very quickly with these claims.
The Texas Health and Safety Code may apply to retaliation of violation of law made by non-government employees in the health industry. The hospital or treatment facility may not suspend, terminate, discipline or otherwise discriminate against an employee for reporting to the employer’s supervisor or an administrator of a facility, a state regulating agency, or what you held to be an appropriate law enforcement agency a violation of law.
