We had an MD who was famous for being nasty if you woke him up. As a night nurse, and a patient advocate, I had to call him many times. For a while I just ignored his attitude and called anyway (I've got teenagers, he didn't scare me). Finally, one night after placing a cervidil, he asked if I needed anything (other orders, etc), I replied that I would just call him, demonstrating by holding a phone receiver at arms length. He just looked at me, then profusely appologized if he ever came across as rude. I made a deal with him, I'd only call him if I needed him, and he'd sign any reasonable order that I wrote. We went over a few things, and have never had a problem since. The joke broke the ice far better than if I "bit back". Don't lower yourself to his standards, be professional, but stick up for yourself. You shouldn't have to work with anyone who can't be professional. Also, does your Manager back you up, can she advocate for you? Use your resources!
