Early 20th century unionisation only happened in the US after pitched battles and gun fights, and when that didn't stop it it was bought off where possible.
A lot of that history seems to have been suppressed to the point that hardly anyone knows about it. It's certainly not something you'll see being mentioned on any mainstream media channel.
yes its disappointing, younger people don't realise how much blood, sweat and tears went into obtaining the working conditions they have now, and as you say, it's not taught much any more.
I remember going to a huge meeting and strike in the 80's, things were a lot more civilised then. I was a young apprentice, there was an older guy who was 'blackballed' - he had turned on a switch against the slowdown rules (a partial strike) - no other worker would talk to him. There were strike funds for people who couldn't afford it, it was a very exciting thing for a young kid, I don't know if it happens any more. People dying on the job so the owners can make more money is nothing new.
