They are working on it. I do have a kick-ass program because they are investigating this seriously. But I have become interested in the big picture and bringing light to this issue.
Currently, there is not a procedure for students to submit grievances or complaints about externship sites. Externships exist as a way for doctoral students to gain necessary hours for internship and additional clinical training. However, some practicum sites exploit this opportunity for unpaid skilled labor.
This site bound externs to a certain number of hours and they were not allowed to "resign" until they met this quota, a form of "indentured servitude". The number of hours had to be met even if the extern was mistreated, promised educational opportunities that did not materialize, or circumstances arose that made completing the full quota unreasonable. I had a verbally abusive supervisor who spoke negatively about other externs in my presence. I did report her to the site but she had left by that time. Even after she left, I was not given adequate supervision or the didactics promised. It was ultimately me, alone on an inpatient unit. My mentor thought about pulling me out but I loved the patients and I felt I could work things out and that it would get better.
Unfortunately, other graduate students were afraid to speak up, especially those from programs that did not have strong internship match rates (not me) as they might hope to match at the practicum site for internship. Other students notified their graduate programs but their concerns were brushed aside (not me) because the programs wish to maintain "cordial" relationships with the practicum site. Some may feel that because they had to serve as free labor for this "rite of passage", upcoming students should as well.
Recently, there has been a lot of press about unpaid internships in various fields:

This issue should have similar traction.
