Telling off a Provider

Has anyone successfully told off an extremely rude, abusive provider and managed to keep their job? My preceptor’s provider is absolute evil and I have a feeling my mouth will get me fired because I refuse to allow people to treat me that way. I don’t prescribe to the “kissing a Dr’s ass” mindset, especially if respect isn’t reciprocated. So, am I an idiot thinking that SOMEONE needs to stand up to this Dr??
