I took a glance at the constitution of the Screen Actors Guild recently as part of a discussion on this topic elsewhere. It's interesting how it features very strong supermajority requirements for going on strike, for imposing a salary cap, and for amending the constitution to remove the supermajority condition.

I wouldn't be surprised to see similar clauses in other union constitutions for fields in which, like tech, there's a large and obvious talent dispersion. I think a majority-rule approach would inevitably lead to the anti-meritocratic policies you're imagining.
