you sound like a republican? Actually I think the best two unions are Masters Mates & Pilots & EBEW Im not real high on teachers union, either is my wife as she taught for 40 years. She was pissed that many good young teachers that performed extremely well would get bumped for seniority regardless of performance. Plus to political.
I'm high on SPEEA where I was a member. I'm also high on the Baker's Union 114 where my wife was a member. I'm high on the bricklayer's union where my father was a member. And I'm high on the Portland Carpenters' Union where my friend's father was their secretary and near life long member. I'm also high on the Teachers' Union where another friend of mine was a member. I'm also high on the Coal Miners' Union because I've heard stories about what coal mining was like before unions when my grandfather was a coal miner in Alabama. I'm high on unions in general because I know throughout history what it was like before there were unions. Read The Jungle by Upton Sinclair.
Those are all good unions. Although I've never belonged to one I do appreciate what they do for the most part. My dad was in the Master Mates and Pilots my sons are in EBEW. Ive got relatives in teachers, painters, bakers, musicians, etc.
