I don't think public pay means you can't negotiate your salary to get paid what you believe you deserve.
Did you ever wonder if maybe your negotiation skills aren't as good as you think? Public pay could be a way of finding out if you are selling yourself short.
It's easy to contact salary services to know what the market rate is for your position. If anything, people with better "negotiation skills" do this proactively, while other people wander and complain without realizing much of this information is already publicly available.
You mean like on levels.fyi? In my experience (as an employee and an employer), their data seems very well aligned to reality. Its main flaw is that itβs US-heavy.
