I would be terrified of what they might say about me in the process, but I like to think I would. There is no other way to protect other people from harm. And surely, even if the t is not punished, someone keeps track of the fact that there was a complaint and notices if there are more than one.
I've been hurt by a t retiring, and by pdoc cancelling appointments bc his daughter was dying. But I don't think those qualify as unethical. But some of the stuff I have read on here, yeah. I think I would file.
