From an April 27 town hall meeting in Iowa:
[…] I’ve said this before publicly and I’ll say it again, I make no apologies for it. I am a pro-union guy.
Our unions helped build our middle class. We take for granted so much stuff — minimum wage laws, 40-hour work week, overtime, child labor laws. Those things wouldn’t have happened if it hadn’t been for unions fighting for those rights. So even if you’re not a member of a union, you’ve got to be appreciative of what unions have done.
