"This is an unfortunate situation. Our code as medical professionals is to do no harm to those we treat. What we do is sensitive work, and physical abuse should not be tolerated. I believe that this goes both ways. Therapists should not be aggressive to patients, and patients should not be aggressive to therapists. There may be some trigger that causes the fellow OT to behave aggressively, but as the medical professional, they should have acted more professionally in the situation. I would document what I saw and report it to my supervisor so that the issue can be addressed. "
