I think a lot of the reasons unions in tech fail to materialize is that every employee sees themself as in the "top performer" group and therefore imagines his or her compensation decreasing in a union. Do a survey of a company's software engineers and ask them if they believe they are among the top 1% of performers in their company. I bet more than 15% say YES.

There are many more below-average comps in tech than above average, because the high end skews really high. So the majority of tech workers should actually see more compensation when negotiating collectively.
