In the country I work it goes like this: the employers are members of an IT association, once a year each employer sends over the anonymous salaries for each job title. The associations aggregates them and sends back the distribution, which HR then uses as a reference. Similar result, but no direct collaboration between employers needed. You can even buy the report for each position as an employee for a fair price.

This sounds similar to what RealPage does in the U.S. with apartment rents: https://www.propublica.org/article/yieldstar-rent-increase-r.... After the Propublica story came out, the U.S. Department of Justice started investigating it as essentially collusion-via-3rd-party.

Seems an odd argument. Essentially information transparency is bad.
