The really awful thing from that story (Planet Money did a great recent episode on the ProPublica coverage) is that they are able to get away with this through Arbitration clauses. By way of their contracts, they strongarm their contractors into dealing with any "misclassification" issues (eg. exerting too much control over a contractor) individually, silently, and outside of court. Contractors have no ability to sue in a class action suit, and aren't even allowed to speak to fellow contractors if they go through arbitration. It's such a sneaky and frankly complicit way to enforce their business model. They know it's grey, and they put people in the corner so they can't call it grey with a loud enough voice for serious attention to be brought to the issue.

Thankfully some law firms have taken the approach to overwhelm Arise with individual arbitration claims. Arise likely calculated in to their model as a cost of business expense, so the best that can be done is to make that expense grow.
