The salary part is for HR department but there must be a clear mission on why you are making the salaries public.
Many tech workers, especially engineers, find salary negotiations stressful. In past start-ups, he had sometimes been desperate to get an app finished and paid way too much to get workers on board quickly. Salary transparency is the single best protection against gender bias, racial bias, or orientation bias». That is why some states now require that government contractors report gender gaps in how they pay their employees. Although many governments make workers’ salary information available, fully transparent private-sector companies still are rare enough to garner headlines.

In addition, pay transparency does not always give the whole story.
