Use legal language when developing your answer. Analyze this case and make a sound and valid argument, stating legal reasoning, along with a final decision.

Scenario Mark, an untenured Assistant Professor of Business Law at a public university, is fired from his job for supposedly misbehaving with students in class. Since the firing took place without any kind of hearing, Mark wants to challenge it on procedural due process grounds. Will Mark's claim succeed? Does Mark's situation require legal due process? Assume that the university did not publicize the reasons for Mark's discharge, and will not tell anyone why he was discharged.
