Texas is an at-will employment state, which means that in the absence of a written employment contract specifying otherwise, either the employer or the employee can end the employment relationship at any time and for any reason, as long as the reason is not illegal. At-will employment does not protect against wrongful termination claims based on discrimination, retaliation, or violation of a specific statute. A written employment contract can modify the at-will relationship by specifying the grounds and process for termination.
