My salary is well-known. It's an equality thing to fix on a standard rate scheme. The rate is known, the stepping is known, and the steps are known. Anyone can figure it out.

And, if not, it's in a yearly report that needs to be released and contains all of that. I could find out how much my entire chain of command makes, at a glance, but I don't care.

Okay; from the daytime job, at least. The side gig is a little variable.
