In some states, including my home state, employers are allowed to pay sub-minimum wage for a training period only. When the training period ends, they often let the employee go. If they keep the employee on, they are required to pay normal wages.

I think it's a good compromise if the price is designed to offset the cost of the training and there's a good chance of a person getting a job outside. The one place I'm familiar with also expects most of the people working there receive disability benefits as well.

I have no idea how Indiana does things.
