> Steelworkers and teachers unions negotiated agreements that based pay on seniority - I can't imagine developers would do anything like that.

Why not? Unions and union members are extremely rational. Are you suggesting that developers would be less rational?

I'm reasonably anti-union but I'd vote for seniority as a union member. It elevates my salary at the expense of people who don't get a vote (new people). It lets me slack off. And, for folks in the bottom half, it's a salary increase.

That doesn't have anything to do with unions.
