I am a female postal supervisor. Our male union president filed false sexual harassment charges against me because he became angered about a management decision I made. The decision was based solely on the contract. A senior employee that he has a personal vendetta against won out over him for higher level pay based on that decision. He said to me as well as others he was was going to teach me a lesson, he was going to fix me etc. He wants management to respect their contract unless of course it negativity affects him. What legal recourse might I have?
