I don't know about others, but what I dislike about unions in the general sense is the history of corruption and hard crime that went along with it in our past.

Who would want a group that bullies their members in order to present a "unified" position to the employer? Sometimes the bullying extended to criminal acts and even murder to protect the union bosses from being exposed.

Certainly unions have and continue to do good things for workers, but we've seen abuses, too.

Just thinking here... What about the limit being only 2 consecutive terms, but either no upper limit on number of terms or a high limit like 6 or 8 terms?

That might allow a chance to see something different, but allow the opportunity to bring back a good person if change didn't work out.
