I kind of had this feeling too, and had several different case workers who seem positive at first, and nothing came my way. They did actually manage to find something part time that lasted a year, after years of nothing, but I spent the entirety of this year with nothing.
I think that what my current caseworker has said is maybe something. She said that a lot of more manual jobs and such can have them able to knock on the doors of places and ask if they have any openings, but in my case where I am more fit for an office job, having an accounting degree, it is much more difficult for them to be able to find openings. The only cases so far seemed to be a perfect case in a sense, that was just part time but a welcoming self owned bookkeeper, and a business that helped employing other people with disabilities but I refused to continue to wait on because incredibly unorganized and left me hanging for literal months that I could have put more work into.
I have no answers on my end, the closest being the one time I got an interview this year, and one over the phone. These only seemed to move forward because I thought that I was a good fit, and rather than rely on any of the templates approved by my employment agency, I wrote it entirely with the job in mind. But I also find that these methods can be incredibly emotionally draining as writing a tailor made cover letter/resume each time can be much more devastating in rejection than just using the template written already. Everyone wants experience, no one is willing to give it.
