union nurse vs nonunion non-nurse

  1. Union RN's are working as data analyst/abstractors in a hospital setting. Hospital has hired a non-union non-medical person to work as data analyst/abstractor in the same area. What are the rights of the union nurses and can they refuse to train a non-medical non-union person? (the training would have to be intense). Will the new person be able to work on the same databases as the RN's? Thank you for any help on this subject.
