Aren't unions overwhelmingly the driving force behind senority-based pay? Honest question. Like, I think teacher's unions are strongly against pay-for-performance.
If anything, the tech industry should be leading the world in new ideas and methods (and dare I say it...technology) to organize labor.
If I join a company and day one I’m the top performer I’d want to negotiate a better package for myself and I don’t want other people meddling in my negotiation unless I explicitly hire them to
I'm coming into it more from the other side, unionization as a way buffer against (and maybe negotiate something other than) sudden mass layoffs.
