I'm thinking that you should look in the mirror.
Like anything else, there are good and bad. I've been in a couple of unions and they were great. Not antagonistic. Labor & management worked together to create superior products in a timely & profitable manner.
As other's have stated reading is fundamental, and my point had nothing to do with unions.
So, since you're new you might want to try and understand the dynamics on this forum vs. jumping into something you don't understand,...yet.
