Reading the story about the founding of the union: https://www.nytimes.com/2021/01/04/technology/google-employe...
It sounds like the purpose of the union is to create a permanent activist-class of employees, who focus on promoting the union instead of doing their jobs, and are protected from termination by the union (or the NLRB). It’s a far cry from from miners who picketed because they were dying on the job.
I’m not going to cry about the mega-profitable Google having a few hundred less productive employees who spend their time on this, but it doesn’t exactly inspire me either.
