Sure, any organized group can hire a lawyer to defend it's members. We are basically saying the same thing. But that is not where the power of a Union comes from. If it were then any class action against a company by it's employees would be a "union". Unions have power because they can negotiate as a group. Those negotiations allow them to do things like get an employment contract for all their members in a company which then affords those members legal rights they would not have under regular employment. If your union doesn't have that legal contract and does not have a practical way to negotiate one then your union only has the power of a larger voice than a single individual and no more legal rights than a single individual at the company does.
