Just cause for dismissal; willful disobedience and serious misconduct practice question

Professor Linda Cruz was a full-time faculty member at a private university in Cebu. Her contract and the university's faculty manual both required her to obtain written permission before accepting teaching assignments at other schools, and stated that violation could result in suspension or dismissal. Despite this, Professor Cruz accepted part-time teaching jobs at two other schools for several semesters without notifying or seeking permission from the university. When confronted, she admitted her actions, explaining that she needed extra income to support her family and that her previous requests for permission had been denied. The university terminated her employment for willful disobedience of company policy. Professor Cruz challenged her dismissal, arguing that the penalty was too harsh given her good performance, lack of prior offenses, and her reasons for moonlighting. Should Professor Cruz's dismissal be upheld? Explain.
