Hi from reading your word i understand that she is your senior , well me my self i've worked with such bad behavior people , my advice to you dont complain to the nurse manager youu only making the situation worse , be patient , try to understand their personalities , for the beginning follow her orders & then by the time when you understand & get familiar with basic routine , take a few steps ahead of her for example : chick your assignment , go to your assigned OR room chick & set up your room . believe me you'll get every one respect & support by the time . good luck .
