When I worked as a stockbroker, everyone in the office knew exactly how much the other people (well, not management, or administrative, but all other salespeople) were making. It was a lot different than the typical office environment where nobody knows other people's compensation unless it's shared secretly. The concept of "open salaries" where compensation is known to everyone is an interesting and beneficial concept to create a more democratic organization.

The concept fits into the organizational management style referred to as "Teal Organizations"
