Perhaps I’m jaded by my experience working for employers that support change and transparency, but I, for one, would immediately pack up and leave if any part of my firm’s white collar workforce unionized. I have zero interest in participating in collective bargaining. I work hard to stand out, and I capitalize on that influence to negotiate raises and promote change on my own.

While I’m sure there are situations that merit such a decision, might I suggest that unionizing < finding another employer that meets your needs. The inability or lack of desire to do so indicates to me either fear of change or aversion to risk, both of which are unwarranted from anyone who is continually working to improve themself.
