Help, I work with someone who lies about everything and everyone and gets away with it even when there is proof she is lying. This is because my boss backs her up every single time and accuses anyone who raises a complaint against her of displaying bullying and aggressive behaviour. A psychologist friend said she thought the colleague displayed covert narcissist behaviour but this was a diagnosis made over a glass of wine, so could be wildly inaccurate. Have you ever faced this situation? What the hell did you do? Unfortunately, I cant leave the job because I'm pregnant.
