because we old Boomers started to see long lines of people for a handful of jobs as a matter of course once Nixon got in and started screwing us over.
Birth control in the 40s, 50s, and early 60s sucked. Families were 3, 4, 5, 6 kids. Once the pill came in, families started to decrease in size. By the time my cohort hit breeding age, fertility dropped like a rock, most of my friends have 2 kids, maximum. That's why there aren't lines of people waiting for those half dozen shelf stocker jobs at Walmart. Boomers are aging out and trying to figure out how to live on Social Security checks or dying from the sheer futility of the effort.
I've been in serious union fights and employers always play dirty, the last thing they want to do is deal with workers who have a little power of their own. Most fights don't result in strikes, the worst that happens is arbitration.
There will be strikes now, employers have been in the catbird seat since the 70s, getting everything their way except conning us into showing up to work for the sheer pleasure of it, none of those nasty old paychecks to deal with.
Unions, it's the only way. I've had union and nonunion jubs and union jobs were better without exception, even the low paying, dead end jobs. We had that tool taken away from us because we were so numerous, we were disposable. You're not. Time to stand up for your rights as workers, citizens, and human beings: unionize that sucker.
