If a person complains to HR about RXM, will it kill their career in a big private company?
My advice, if the situation is so unbearable that your next step would be to leave your job, or if something illegal is going on, then definitely go to HR, because you don't have much to lose. Otherwise, I would try to bear the situation and hope that you outlast your manager, or try to transfer to another store or hospital in the system.
Yeah, yeah, "good faith non retaliation policy" really doesn't mean anything. Whether it will kill your career depends, but there is certainly a good chance of it. Count on everything you say to HR being repeated back to your manager (even if they promise you they won't.) Of course, you could try registering an anonymous complaint, but depending on how specific the situation is, your manager may have a good idea that it is you.
