Capitol bracing for right-to-work vote protests; unions plan next moves | The Detroit News | detroitnews.com I called this a while ago, but it happened even faster than I thought. A lot of Teamster union dues will disappear if the next contract doesn't do more to help the part timers. 80% of the people on my preload are ready to withdraw already. Most common reasons stated, they don't feel they're being equally or adequately represented compared to the full timers. The other is that the part timers due to numbers pay the majority of the union dues to negotiate contracts that give the lion's share to the minority and leave them behind. Hard to argue. Union is going to have a tough sell, at least in my neck of the woods. They're going to have to show where the value is for the average part timer to become or remain a member.
