They can still work for less as a contractor, if they want, right?
For example, if Subway determines how, where, and when I make the sandwiches, and provides all the equipment and materials, then I am a de facto employee. Even if both Subway and myself voluntarily agrees that I am a contractor for whatever reason (sidestepping minimum wage laws in this case), and signs a service contract to that effect, I am still treated as an employee under the Fair Labor Standards Act.
