Do What You Gotta Do and Go Home!
I don't know why any person with free choice would choose to take a route through life, work, dating, etc. that would make their life more difficult and filled with more drama. Unless this person needs to be evaluated by a professional (read: psychiatrist), it just doesn't make sense to continually walk yourself into a bad place.
How many times does anyone need to be asked to do their job and to do it correctly? I've started asking associates the question, "How is what you're doing helping us meet our goals today?" And, nearly every time they look at me, blink a few times, and fail to answer. They will eventually say something like, "Wow, you really put me on the spot!" or "I guess I'm not doing anything," or "I don't know how to answer that."
That's the point!
If you have no justification for doing what you are doing, when it goes against what is expected of you at work, then you are providing both the ammunition and the gun to your supervisor and employer and you should not claim that you are a target of someone's personal vendetta.
Just do what you were hired to do and go home. If you are doing the right thing and someone comes after you, it's a whole lot easier to try to prove you've been wrongly targeted for racial or other reasons, then if you are a low performer still being targeted for those same reasons.
Don't give a racist in your workplace a legitimate reason to come after you. Keep some of your power and control what you can!
