Hi tumbleweed. I am a psych RN and have worked on an inpatient unit with psych techs in the past, but currently work in an outpatient clinic. In my experience, duties of the psych tech, included a lot of the work out on the floor with the patients, although the nurses do have duties, i.e. groups, etc. but the ultimate responsibility for the entire unit lies with the RN. A lot of the psych techs I have worked with are also CNAs, some were not. I guess if I had to define what their duties are, I would compare it to that of a CNA on a medical unit, and I may risk getting bashed for saying that, I certainly don't intend to offend anyone, that's just my understanding of it. I assume the majority of psych techs have other specialized training in psychology, but honestly I don't know what the educational requirements for that position are.
Re your question about anomosity, no way could I answer that. But if I had more info re what you mean, I could perhaps speculate, but even that may not be fair.
I am curious about your questions, not knowing which side of the fence you're on. Although there really shouldn't be a fence.
Have I been vague enough?
