Care to expand?
Even though it is illegal to fire someone for discussing salary, that and a nickel will buy me a piece of five cent candy.
If they make more than I do, what am I going to do with that piece of information? I can’t very well bring it up at salary negotiations.
Besides, I have been around long enough to know that the best way to “get a raise” is to change companies.
If a coworker told me their compensation, I would not reveal that in a discussion about my own pay. I hope that the reverse is also true. I think it's a mature and cool-headed position to have. Not everybody is mature and cool-headed though.
I have also heard the best way to get a raise is to move companies. I like my job though.
I work for a large company with a well defined level structure. When I need to, I’ll say around $XXX, where XXX is what Glassdoor / levels.fyi says. It’s pretty close to accurate, and it also rounded enough that coworkers can project whatever number makes them happy.
