After all, why would tech workers choose that pay scale when putting together the rules for their union?

(And, if they did choose that, whose place is it for anyone outside the union to tell them that's wrong?)

travis stated pay is based on seniority (implied most, not all). You claimed his sample was too small, then gave a small sample as counter-evidence. So now that I ask you if the majority of people in unions are paid based mostly on seniority you admit you don't even know? And thus claim it's irrelevant?

That's an odd way to demonstrate that your objection has merit.

You can look up the biggest unions in the US, and you will in fact see that a significant component of pay is seniority based for the majority of people in US unions.

If you're going to complain that someone is wrong, at least put in some legwork.

If tech workers unionize, they can decide whatever pay scale they want. Why do you think that is not so?

And if they choose a pay scale based on seniority, lines of code delivered, or the weather, what difference does it make to you, someone presumably not a member of their union?
