I think everyone is generally stressed in a health care position. It's not an easy job either way. My best friend is an Occupational Therapist and LOVES her job. I've noticed the Physical Therapist and Occupational Therapist seem pretty happy with their jobs. It might be the autonomy of job. But to be honest, in my clinicals as a nursing student most of the nurses I worked with said they loved their job. Why do you pose such a question? Are you considering changing your career?
