I find this interesting because I don't fully understand how tech became so opposed to unions. Many in our industry are quite jaded about the poor behavior of large corporations. Perhaps there are also reasons to be distrustful of unions. But mostly we accept working with or doing business with the former, and entirely eschewing the latter. Why have we decided that untrustworthy, sometimes poorly managed organization…
Companies don't own the workers.
A steelworker can only do what they are skillfully specialized to do by using capital goods own by the company. Hence they can't negotiate with their feet (leaving) while a tech worker can.
Tech workers can work (remotely) for virtually any company in the world.
A farm worker can't.
All this may change in the future, but with some privileged tech workers (I'm not one of them) being able to retire in their 30s and 40s now I don't see why as a whole the industry is incentivized to unionize.
