I think our are taking about a professional organization. Those do not perform the same function unions do. The point of unions is to gain bargaining power against massive corporations. If you are self employed, part of a small company or easily replaceable (which is the case for most lawyers), because your professional is only a tiny part of the company a union does nothing for you. Professional associations exist for different reasons and have different goals.
