Nah, I was raised by someone who worked for the UAW and I was on strike when I was 17 years old working at a local grocery store for a few weeks. My old man said the union was pretty much useless outside of him being able to retire a little early due to the Edison plant being shutdown.
The issue is that the vast majority of the time, the union is a self serving entity with ties to ideologies I don't particularly care for.
Demographically unions may have more influence due to a shortage of workers due to smaller cohorts and labor becomes harder to fill in certain positions. But to blindly put your faith into a union is downright stupid.
