I recently worked on a group project for our ICU to make staff aware of real life bully situations in the workplace. We found great resources on the AACN website to address cases like these. The best way to handle this situation is to pull the physician aside where you can address your concerns to him. If you are unable to speak with him one on one, then escalate it to your nursing leaders as appropriate. Bottom line, no one should have to deal with bullying at the workplace. Best of luck!
Here is the link of the resources we used from the AACN website.
