Bullying, harassment, and abuse are serious and far too common in the medical profession. Recognizing these behaviors—and knowing how to respond—is essential for protecting patients, supporting colleagues, and fostering a healthy workplace. This chapter defines bullying, harassment, and abuse, drawing on the official definitions from the U.S. Equal Employment Opportunity Commission. It offers practical advice on how to respond effectively when faced with these situations, whether you are the target, a bystander, or in a leadership role. By learning to identify and address these issues, you not only safeguard individual well-being but also strengthen teamwork, improve patient care, and contribute to a more respectful and supportive healthcare environment.
