Assuming that you can prove the hostile intent of the employees' conduct (and the apparent condonation by the employer), then you have an action for unlawful discrimination against the employer -- if for nothing else, then for emotional injury.
The problem with these lawsuits is that once you file, all of your coworkers who said they would testify in your behalf, suddenly have a case of "selective memory loss," because they are all terrified of losing their respective jobs.
So, your real case depends heavily on finding independent evidence of the bad acts of your coworker and supervisor.
Regardless, on the facts as you state them, you do have a claim.
You can file a charge directly with the Department of Fair Employment and Housing
, or you can hire an employment rights attorney
Hope this helps.
