There is no such thing. A problem with a union is that everyone's going the same place, and you're not driving. Maybe that place is better than where you could get to on your own, or maybe not. But one thing that is definitely not true is that your union is going to do exactly what you want.

There really is! I've been in three unions, every place I worked. The first and third one existed beforehand, while I helped start the second.
A union is a group of people—and like any group, your influence is what you make it to be.
