It seems like you ignored my original post, which explained exactly why that idea doesn't work, and why your continued talk about "inefficiency" and ragging on tenure is ignorant. I'll restate. Labor has to be a single unit in order to negotiate on equal terms with capital. Since unions are formed in a given workplace or industry, it's not like a union or local can negotiate with multiple employers in order to gain leverage. That concept kind of exists in the form of consulting agencies, but they fill a much different niche. Unions optimize their power structure for continuity and cohesion - the efficiency of their employer is highly, highly secondary. This is a good thing, as stable unions means a stable middle class, and low social unrest. Minimizing the labor cost of American businesses is not the end-all, be-all of social KPI. Based on your comments, I'm guessing you have a specific political bent, but if you do the slightest bit of research, you'll find that people of all persuasions push their ideology via the School Board. Texas is a particularly famous example of right-wing ideologues re-writing history in their way. Unfortunately the humans seem to be the weak point of the system, so the only thing you can do is be involved and build a strong community.
