I feel like the provider is creating a file against me. Since I was only hired to answer phones and book appointments, he doesn't provide much support or direction when he tells me to do other administrative tasks that I have not been trained to do, that his front office assistant does.

I feel like I'm being undermined and sabotaged by this guy. He wants me to do (A) but won't train me how to do (A), then expects me to just do it. And if I ask him to show me how to do (A) he undermines me by telling me that I should know how to do it, i.e. gaslight me. He also said he isn't going to be a reference for me since according to him, I'm making too many mistakes. He also spends a lot of his time on his cellphone. People like him, who don't communicate or train their staff, yet expect their staff to just do things (mindread) are immature and passive aggress.

Toxic boss? Yes, he definitely is. He doesn't want to train me how to do other things and then expects me to do them anyway, then may report to my recruiter that I didn't ask him for help and made a lot of mistakes. All I've tried to do is get away from the substitute teaching and contract temp work to a full-time job. Yet, no luck. And I've taken the steps: career center workshops, resume help, networking through social media and in person. I'm not making headway due to my resume content (relevant experience is older than ten years) and my age, and that is very frustrating.
