In my experience the best way to deal with this is just to work very hard and suck it up, also to try and pick up on anything your senior is disapproving of and fix it.
The thing is, you will have to work with people in life that you don't like, and some who don't like you or the way you do things. You just have to try to get along with them regardless. I think it might help us (here on SDN) if we knew what behavior(s) you are experiencing that you feel are abusive. If it's someone screaming and swearing at you, then I agree, but if it's just someone being critical of the way you do things, you may just have to deal with it and move on. Try to pick out which thing(s) are valid and correct them, but don't obsess about one person "not liking" you. It's just something we all have to deal with at times in life.
If you get into a power struggle with someone above you, almost 100% of the time they will win. Interns and med students don't win in these types of conflicts. Residents don't win if they get into disputes with fellows or attendings. Forget about how "unfair" it is and just try to get through. Otherwise you might get your head served up to you on a platter like John the Baptist.
