Need advice, please.

I had a co-worker approach me and ask if I knew anyone that could apply for a position in their department. I said, I will have to check. I came back with a gal/long time friend that was interest. She applied and was hired, however, I feel sad and angry that I got her hired. The department and ladies in that department are nothing but barracudas! They are not nice to her, they are rude, condescending, disrespectful, they alienate her. She is the kind of lady that would give you her last dollar. She has been on the job for 15 days when the gal went on vacation. I will call my friend, Val, Val was left alone to handle a new job that she was not fully trained for, so much information, and it takes up to a year to learn this position. When the other gal returned from her vacation, Val, was met with anger, condescending tones, and was told that she messed things up, and now she (Karen) has to do her job and her own job too! And, maybe this job just isn't for her (Val. In the mean time, the front desk receptionist has treated Val with disrespect and blatant rudeness, no greeting, low tone of voice, no eye contact. If they cross each other, the receptionist will quickly turn her head and look the other way, or if Val is walking towards the receptionist, the receptionist will quickly turn her body and head. She will not say goodmorning, although, Val, does say good morning. When family member comes to see Val for a brief minute, the receptionist is not warm or welcoming, but disgusted and condescending. I feel terrible I put my friend Val, in this situation. She left a job she was at for 12 years to give this job a chance thinking it would be a better opportunity. But none the less, it's been nothing but trouble for her from the day she was hired. She is in her 90 day probationary period, giving her limited security for her position within the company. It is very unsettling and unnerving that we have ladies that cannot be professional, helpful, be a team member, and do what's best for the sake of the company and it's values. I am deeply sadden with all of this. I am the Executive Assistant, and as hard as this is, I need to remain neutral in such a negative environment and now that my friend is involved. I cannot become personally involved, but need to remain professional, on task, a teammember to support all within our company to and become the best of the best. The conflict has had a bearing weight on my shoulders and weighs heavy on my mind, especially since I helped get her hired here. I have considered talking with my reporting Vice President, but I don't want to come off as this being personal. I have encouraged her to speak with her Supervisor to relay her concerns and issues with her first, if she feels there is no resolve, then consider going to H/R to place a complaint. I feel this is really getting out of hand and needs to be addressed. If Val had made mistakes, I would have researched why, explained to her how she made them, and explained and showed her how to fix them so she understood going forward. I would not ever have given her the ultimatum that maybe this job isn't for her!! I also feel they are already trying to push her out already without giving her a full chance. The negative, back biting, gossiping, barracuda pit has been in existence here for many years, one would think that the stagnant kind of environment would come to an end at some point by growing up and becoming mature adult woman that will support one another to success. Not the case here!! What would you do?
