YABU. If you banned unpaid internships a huge chunk of this country's MH services would collapse
That is training and quite different.
Not really. Clinical placements are usually organised by the student, not by the training institute. Most placements provide zero or very limited training as it is expected that volunteers are trainees at one institute or another. Some don't even provide supervision and expect the volunteer to pay for private supervision.
What volunteers are getting is on-the-job experience, unpaid. They need this in order to qualify - hundreds of hours of it, in fact, in order to gain accreditation. I don't really see what the difference is between this and an unpaid internship in, say, a bank, for the purposes of gaining work experience. If anything it's more exploitative because arguably you don't have to do an unpaid internship in a bank in order to get a job in one.
And the fact remains that without this unpaid labour - effectively internships - most poor people wouldn't be able to access counselling of any kind.
So again: if you want unpaid internships banned, you're also effectively arguing for the withdrawal of MH counselling services from people on low wages.
