I have had to endure a hostile work environment the last 9 months and have kept a journal, emails, and texts from my GM. She has been here 10 months and I, 5 years as maintenance supervisor. She has written me up for insubordination several times (when I had none the previous 5 years) , accused me of wrong doing, and said my male testosterone is the reason for my insubordination. I am the only male manager out of 5. I have witnesses to dispute her accusations. She has called my regional a girl and that he acts like a woman in front of me. This started when HR sent a rep to talk with us managers about how she is doing so far. After that meeting she called me in her office to ask who said negative things about her. I have more but not enough space.
