My name isXXXXX a licensed attorney. Glad to try and help out.
Sure sorry for your circumstances, truly. My heart goes out to you.
I'm also a registered nurse, so I commend you being a conscientious professional.
Here's how this works, having read and carefully considered everything you're shared. You can (and certainly should) report your concerns, free of charge, to the U.S. Equal Employment Opportunity Commission (EEOC). Everything he needs is provided here (please just click the following link):
Filing A Charge
You deserve to be treated properly, and if you want to pursue the matter your next step is to file your complaint. This is an exclusive remedy, meaning you must follow this process first, rather than going directly to a lawsuit. You have more than enough solid reason to proceed here, in my estimation.
Now, here's why I say so. Your mention of being signaled out based on race brings up a serious legal issue called "disparate treatment". It's a form of unlawful discrimination, and the way it's remedied is by filing a charge as outlined above.
Now, if you do end up need to have your case screened on the merits by a plaintiffs' trial attorney, the good news is that process is also entirely free of charge to you. Should it come to that point, my very best recommendation would be to take advantage of the resources of the non-profit, American Bar Association accredited, National Board of Trial Advocacy Division of the National Board of Legal Specialty Certification. Here is a listing of all such Board Certified Civil Trial Advocates practicing in your jurisdiction (please just click the following link):
Please know that you deserve to be treated properly. I hope you see justice accomplished.
If you have a follow-up question or need clarification, please just say the word by using "reply" to reach me.
I truly hope all works out for you and that things look much brighter down the road.
