>> their influence should not exceed those individuals directly affected by the company or union.
Why not? And in any event, how would you measure it?
For example, my company each year makes an effort to give to the United Way. So we have a meeting, and they give us the nice pamphlets from United Way explaining what they do. But my company doesn't run commercials outside of the company prompting United Way. That is the limit I was thinking about.
To be honest, my thought is more idealistic than realistic, and I haven't thought about all of the unintended consequences yet.
