Aw, that was one of the fun moments when getting my current job. I moved from private sector to public sector and they're like "You understand that the previous pay you listed is more than our boss's boss, the director of our entire org unit gets paid right?". Yes, yes I do. Which is why when you asked at interview "Why do you want this role?" I didn't say "Because I would like to get rich".
But overall this seems like a good idea. Pay transparency is a known good strategy. I remember years ago working for a huge international corporation I asked about pay transparency at one of those bogus "Ask us anything" board events and the CEO answered and he's like, "My pay is a matter of public record because that's the law here" and I'm like "Yes, and it's fine, you can see that now so why not the same for everybody else?" and of course he just deflected.
How "inability to give a straight answer on anything" and "refusal to make any meaningful decisions" came to be considered good leadership traits is a mystery to me, but I do know how much it pays so that's nice.
