If a recently unemployed person wishes to sue for wrongful termination in Texas, he must comply with state law. According to legal experts, it is difficult for plaintiffs to win such a case in Texas, since most employer-employee relationships are "at will." That is, an employee works for an employer at his will: the latter can lay off or fire the former at any time and for any reason, unless it is expressly prohibited by state or federal discrimination laws. According to federal law, a person may not be fired because of his race, gender, age, or religious beliefs. Therefore, it is extremely difficult to prove discrimination where the "at will" relationship is the most common type of employee-employer arrangement.
