Well, out and out assaults, I have never seen(in 6 or so months). I work with some of the sicker people in the state and rarely hear of such happening. If you build their trust and listen to what they have to say, you should be ok. I have seen cases where a Patient has built up to going after a staff person. For instanse, one patient did not want to be discharged-refused to in fact-but the social workers kept working on finding a placement for this Patient. The patient mentioned several times of assualtive behaviors he was going to do if they kept working towards his D/c. And he did end up inadvertently hurting a tech. But the build up was long and drawn out. My point being, there is usually a way to intervene a problem before it happens. If for nothing else, your own sake.
Keep your eyes and ears open. You should do great. All in all, techs-whether degreed or not-learn 99.999% of the skills on-job.
Just curious, what type of facilitys have you interviewed at? Residential,Private hospital or a state run facility?
Best of luck. You will be building great skills for whatever field you decide to go into to. Feel free to PM me, if you want to talk further.
