I'll always remember my mom picketing and striking TWICE to extra a NICKLE from local management of an electrical sweat shop...she was UAW...

I remember my Mom picketing as a public school teacher. And I remember her cross the picket line when she concluded the union was asking for too much. And I remember the phone calls threatening her kids and the nails in our driveway.

I agree that unions did a world of good. But notice how all of your examples are from the past. It was because of their achievements that the became less necessary. The workplace improved vastly because of them, but they never changed. They never recalibrated. They never called off the dogs. And they paid the price.
