Sorry for what you are going through but your preceptor and those like her/him want you to leave that's why they are making those comments. They are afraid of change. They fear what you represent. For you to leave without a fight means they have won. They hope you are weak and will just bow down and quit. Look at every civil rights movie/book made (ex. Selma, The Butler, The Help). These were based off true stories and if Black people didn't fight back we would still be in that position today. They went through the same thing you are going through now except worse because they didn't have laws protecting us like we have now. We (meaning Black, Latino, Asian,females and any other non white race) have to enforce those laws when injustices occur. Don't let them (the racists at your job) get away with it. That's exactly what they want you to do. Don't just do it for you, do it for others that come after you and the patients of color that go there for care and possibly get mistreated as a patient. Here is a website you can go to:Dealing with Discrimination: Tips for Employees - FindLaw. I would notify HR and the EEOC at the same time. HR took part in hiring you so they know the law and have to do something about it. I would also check in with a civil/equal rights attorney as well as they can guide you on what to do. Companies have been sued in the past for allowing discrimination for millions of dollars. One such case happened to a female doctor being sexually harassed by other doctors. She wound up quitting then suing the company and won. But like some of the other commenters wrote, you need to write down who said what and when and keep any evidence that they used to taunt you. I would do all of this while looking for another job. Don't let them know that you are looking though. Keep that a secret or they will just wait for you to leave and do nothing. I heard it was hard for nurses to get jobs now especially if you have no experience. So, don't let them kick you out before you at least get a year under your belt although 2 yrs is better but just explain to your next job about the discrimination and they would surely understand.
