I was a Teamster, loading and unloading trucks on the freight docks in Dallas when I was an undergraduate. I didn't break legs, but I made good money. Apparently, Hoffa was corrupt, but as TB points out, he obtained some pretty good pay and benefits for working men. Unfortunately, he didn't know his limitations.

I was also a steel worker and a construction laborer both of which had unions I joined. At least in part because of unions, businesses learned to treat their employees better than they had. Will they continue to do so? If not, unions could make a comeback
