If unions are about collective and not selective workers rights, what types of workers rights are missing not only at Google, but FAANG? We hear lots about unions... or lack of them stifling access to opportunity or innovation, I’m curious to learn more about: - What a modernized or reimagined practice of a union could look like where it wasn’t anchored in the world changing slowly, instead of quickly? - How might a reimagined union focused on today’s issues with today’s approaches in the 21st century look and start much differently than one incarnated a few hundred years ago? Is there a step change possible or already occurred in some cases? - How can unions overcome the issues that other bureaucracies (enterprise, Govt, education, health, etc) experience, including in some cases inhibiting change at the goal of self preservation?
