have 2 staff nurses who have poor behavior,shunning the charge nurse if things do not go their way. for a long time we had no admin. staff and this has been going on for 2 plus years. they do not go to the charge nurse with concerns but have mx. complaints behind her back. both have good clinical skills but see no other view points other than their own. i see very passive aggressive behavior. one issue has already been taken to human res. and she has been given a written warning. their culture is different and they are both very position and money oriented. one is a md's/officers wife. i am at a loss as to what to do? as the charge nurse/supervisor i could walk on water and it would not change their cruel behavior! any ideas would be most helpful.
