I live in California. I quit a job three years ago because a fellow worker made my life at work a nightmare. This was not sexual in nature, just plain rudeness, mean-spirited, un-professional. She even clean out my desk one day because she decided she wanted to work there and basically shoved me out of the office. Our employer knew of this behavior and did nothing to stop it. She even agreed that I deserved an apology but would do nothing to help me. I did not document any instances frankly because I didn't think it would get so bad. Then when it did, it was too late. Do I now have any recourse legally? I also suspect that employer spoke ill of me when I used her name as a reference. Can you give me some advise?
