I don't disagree. That's why I said you can file your taxes as an employee. Presumably, since he kept the position, he was paid a living wage in cash flow terms. Filing taxes as an employee forces the IRS to investigate, and expend their resources, rather than your own. If they do find misclassification, they will inflict punishment on the company and force them to reclassify any other contractors.

I'm not sure what else you can ask the state for without severely limiting the economy -- any investigation by the state is going to take time and there will be ambiguity. But, if your work was directed explicitly (such as being told you had to do it), you are pretty much guaranteed you are an employee. The IRS is really nice and they will act on your behalf.
