I am the only female on a team of 6. I have been at this job for 1.5 years. From the very beginning, a co-worker has called me ugly, said he hates my voice, spread rumors that he thinks I have aids, told my boss he thinks I am on drugs, tried to get me fired by lying to my boss and HR.He even told my boss all these things so he is well aware! I never complained. I just sat back and overheard my boss's boss defend me and say "it is because I am a woman". However, nothing was ever done about things. It got worse: my boss started conspiring with him against me to protect him! In fact, I complained to my boss and the result was I was demoted! So, I quit because the emotional toll was unbearable and I am happy at a new job. Can I still sue?
