A woman has been spreading rumors at work, which include saying I am having sexual relationships with different men. This has been going on for well over a year ever since she became infatuated with a male co-worker and was driving by his house repeatedly and saw my car there. She has repeatably also been trying to get me in trouble with management by going and complaining about my work habits. She has made and done different statements and actions that worry me about her mental stability. I have complained to management only a handful of times because I didn't want anyone to get in trouble. Yet it is not getting any better only worse. Management does not seem care or believe me... What can I do to insure that I won't lose my job because of this person?
