I don't know anything about Texas, but in GA, if there was any question about the appropriateness of my UIB claim, it would be made through correspondence delivered through the postal service, not the phone. And certainly not from anyone out of state. In GA, there is a window during which either the applicant or the former employer can appeal an initial judgement for or against benefits. I've had that happen to me twice, both times the decision came down in my favor.

However, if the employee was fired for negligence in breaking a piece of equipment he was supposed to be trained to operate or manage, there may be a justification that they were fired for cause. The question then is whether there was some sort of appeal filed within the defined window.

I don't know who TWC is, if they are a legit organization, a representative of the government, or what. X may want to contact your state's department of labor directly to find out, and not saying anything further over the phone which they may be recording (for training purposes).
