Would you like to pass the hat, and raise funds to charter a new organization? I would contribute. Who will herd these cats?
It's an unfortunate fact, but even with another organization, the same people will gravitate towards and be elected to the leadership positions by the same people who are regularly voting now in elections, regardless of what name you care to hang over the door of the union's/association's hall. These are the ones whose calling is in sales rather than union representation, and would better fit in with the cutthroat and egotistical management/office world.
As now, they will be those who expect something for nothing, who really don't care to work in their trade, take more pride in being "important" than doing their job well, and have no problem kissing the posterior of those who spend their lives looking for way to hose their friends, the rank and file, all for a few extra scraps than normally is allowed the peons and serfs. All this - virtue of willing to spend the required time under their boss's desk rather than take pride in themselves.
While there may be a very few well meaning individuals involved with the TWU, I believe the majority of the TWU "Importants" fall into this description.
We'll never be rid of that manner of people unless we first not allow them a place to take root as we collectively have by way of tolerating this bad joke we call a union and its unwillingness to function as it should, seeing to it for its membership's sake the company is bound by contract to do as it promises and making the company live up to those agreements.
Unfortunately, it's against the law to deal with this waste of humanity in a fitting and appropriate manner - ie, removing them from union membership and subsequently, their jobs and simple presence among those with even a small amount of honor.
