So then change the 2/3s language
It could be possible to change the 2/3 language. Like, if less than 40% turnout, then over 60% to ratify would be much better.
Honestly, I think it should be just majority of voters rule. I understand the thinking of adding in the less than 50% turnout, but by not voting, they are choosing to give up their say. As it is now, buy not voting, they are making each yes vote worth twice as much as each no vote.
To change it you would need to get a proper proposal started a few months before January (like now). Have it checked with a lawyer so Hoffa can't veto it for language issues. Spread the word around. Then submit it to the union. It will be read at 3 union meetings, then put up for a vote.
We could also do the same thing about how their raises are calculated. As of now, it's based on inflation. It should be based on member's pay. For instance, take the full time inside/inside 22.3 job as the basis. Whatever it gets as a percentage increase in a year, that's what those who run the union get for a percentage increase per year.
